Tropical Depression One
A tropical wave exited the west coast of Africa on May 23 and tracked westward across the Atlantic Ocean and the Caribbean Sea. The system had entered into the Gulf of Mexico on June 6. Another tropical wave merged with the system on June 7 and developed into a low pressure area in the Gulf of Mexico. Later that day, the National Hurricane Center began classifying the system as Tropical Depression One. Though the depression was predicted to intensify into a tropical storm, strong wind shear produced by an upper-anticyclone prevented significant strengthening. The depression tracked slowly and erratically through the Gulf of Mexico. By late on June 8, a reconnaissance plane flight indicated that the depression had degenerated into a low pressure area. The remnants of the depression produced gusty winds and light to moderate rainfall along the Gulf Coast of Mexico; some areas in the state of Tamaulipas reported precipitation amounts as high as 7.18 inches (182 mm). In addition, heavy precipitation was reported in south-central Texas.
Tropical Depression Two
A tropical wave emerged off the coast of Africa and quickly developed into Tropical Depression Two on June 23. Although it was well-organized, the National Hurricane Center did not initiate advisories on the depression until 1500 UTC on June 24, since it operationally appeared that a surface circulation did not existed until then. However, the depression was less organized after the National Hurricane Center began advisories. Having formed at 19.8°W, it was one of the easternmost developing tropical cyclones in the month of June, even further east than Tropical Storm Ana in 1979 and Tropical Depression Two in 2003. Though light wind shear and marginally warm sea surface temperatures (SST's) were in the path of the depression, no significant intensification occurred as it tracked generally westward. The depression began encountering a stable air mass, and degenerated back into a tropical wave on June 25.
Main Article: Hurricane Alberto (2000)
A well-developed tropical wave was observed in satellite imagery over central Africa on July 30. The system tracked westward and emerged into the Atlantic Ocean on August 3. After entering the Atlantic, the system rapidly organized, and developed into Tropical Depression Three at 1800 UTC that day. The depression moved west-northwestward at 17–23 mph (27–37 km/h) and strengthened into Tropical Storm Alberto early the next day. While briefly turning westward on August 6, Alberto had reached hurricane status. Alberto continued to track west-northwestward, and by early the following day, the storm reached an initial peak with winds of 90 mph (150 km/h). Shortly thereafter, Alberto re-curved northwestward. A strong upper-level low increased wind shear, which caused Alberto to weaken back to a tropical storm on August 9. However, it quickly re-strengthened, and early on August 10, Alberto was upgraded to a hurricane again. Due to a break in a subtropical ridge, Alberto gradually curved northward and north-northeastward between August 11 and August 12. While turning northeastward, Alberto further strengthened into a Category 3 hurricane, becoming the first major hurricane on the 2000 Atlantic hurricane season. By 1200 UTC on August 12, Alberto attained its peak intensity with winds of 125 mph (205 km/h). Increasing upper-level westerlies caused Alberto to weaken as it moved east-northeastward, with the cyclone losing most of its convection. Early on August 14, Alberto was downgraded to a tropical storm. A westerly trough that had been guiding Alberto outran the storm, and strong ridging developed to the north and west. As a result, Alberto turned southward on August 15, southwestward on August 16, and then to the west on August 17. While curving northwestward and then northward, Alberto began to re-strengthen, and was upgraded to a hurricane for the third occasion on August 18. Alberto reached a third peak intensity as a Category 2 hurricane with winds of 105 mph (205 km/h) on August 20. After weakening back to a Category 1 hurricane, Alberto had completed a cyclonic loop, which it had started on August 13. Due to decreasing SST's, Alberto was again downgraded to a tropical storm on August 23 as it accelerated northeastward. Six hours later, Alberto transitioned into an extratropical cyclone while centered about 780 miles (1,260 km) south-southwest of Reykjavík, Iceland.
Tropical Depression Four
An area of low pressure detached from a frontal zone on August 4 and moved southwestward. After developing a minimal amount of deep convection, an Air Force Reserve Command reconnaissance aircraft found a well-defined low level circulation on August 8. The depression then moved westward without intensifying for two days. On August 10, the depression was about 80 miles (130 km) east of Cape Canaveral, Florida when it abruptly turned northeastward in advance of a deep-layer trough over the eastern United States. After minimal strengthening, the depression dissipated to the north of the Bahamas on August 11. While a tropical cyclone, a reconnaissance flight reported winds of 56 mph (91 km/h) at 1,500 feet (460 m). However, it was not upgraded to a tropical storm since the aforementioned wind speed did not represent the intensity of the depression.
Tropical Storm Beryl
Main Article: Tropical Storm Beryl (2000)
A tropical wave emerged from the coast of Africa with a closed circulation on August 3. However, the system split, with the northern portion eventually becoming Hurricane Alberto, while the southern portion of the wave continued westward. Minimal deep convection developed until the tropical wave reached the Yucatán Peninsula on August 12. After emerging into the Gulf of Mexico on the following day, satellite imagery and Air Force Reserve reconnaissance aircraft indicated that the system developed into Tropical Depression Five at 1800 UTC. Early on the following day, the depression intensified into Tropical Storm Beryl. Despite predictions for Beryl to reach hurricane status, it remained disorganized and peaked as a 50 mph (85 km/h) tropical storm. By 0700 UTC on August 15, Beryl made landfall about 35 miles (56 km) north of La Pesca, Tamaulipas, Mexico with winds of 50 mph (85 km/h). Beryl quickly weakened inland, and was downgraded to a tropical depression five hours after moving inland. Shortly thereafter, Beryl dissipated while centered near Monterrey. In Mexico, Beryl dropped light to moderate rainfall, especially in the state of Tamaulipas, which peaked at 9.76 inches (248 mm). One person drowned due to flood waters in northeastern Mexico. Damage was light, totaling to $27,000 (2000 USD).
Tropical Storm Chris
A tropical wave exited the west coast of Africa on August 12. Although large amounts of deep convection accompanied the system, it was displaced from the poorly-defined center. Over the next few days, convection consolidated and by 1200 UTC on August 17, the system began as Tropical Depression Six, while centered about 690 miles (1,110 km) east of the Lesser Antilles. Outflow was initially limited due to light wind shear, though the depression was forecast to become a strong tropical storm by August 20. It was "highly surprising" to the National Hurricane Center that the depression did not immediately begin to intensity, despite warm sea surface temperatures and light wind shear. Because of a burst in deep convection, as well as satellite imagery estimating winds of 40 mph (65 km/h), the depression strengthened into Tropical Storm Chris at 1200 UTC on August 18. Upon becoming a tropical storm, Chris attained its peak intensity with winds of 40 mph (65 km/h) and a minimum barometric pressure of 1,008 mbar (29.8 inHg). Because wind shear was believed to be weak, further intensification seemed very likely. Unexpectedly, Chris weakened back to a tropical depression by 1800 UTC on August 18, after having been a tropical storm for only six hours. However, the National Hurricane Center operationally held Chris at tropical storm intensity until early on the following day. Convection was nearly non-existent early on August 19, though there were a few small bursts in convection. Later that day, a reconnaissance aircraft flight into the storm found no circulation, while a QuikSCAT pass indicated an open wave. As a result, Chris dissipated while east of the northernmost Leeward Islands at 1200 UTC on August 19.
Main Article: Hurricane Debby (2000)
A strong tropical wave exited the west coast of Africa and entered the Atlantic Ocean on August 16. No significant development occurred until August 19, which was when convection began consolidating around a well-defined low-level circulation. As a result, the system became Tropical Depression Seven at 1800 UTC on that same day, while located about 1,035 miles (1,666 km) east of the Windward Islands. Favorable conditions allowed the depression to become Tropical Storm Debby early on August 20 and further strengthening into a hurricane occurred 24 hours later. At 1200 UTC on August 21, sustained winds peaked at 85 mph (140 km/h). Debby made three landfalls on August 22, in Barbuda, Saint Barthélemy, and Virgin Gorda, before re-entering the Atlantic north of Puerto Rico. As Debby was beginning to parallel the north coast of Hispaniola late on August 23, it weakened back to a tropical storm. Unexpectedly, the storm continued westward and weakened further, instead of approaching Florida and strengthening into a major hurricane. While south of eastern Cuba on August 24, Debby was downgraded to a tropical depression, six hours becoming completely dissipating. Light rainfall and gusty winds caused minor damage in Barbuda, Saint Martin, and Trinidad and Tobago. Brief blackouts and damage reaching $200,000 (2000 USD) was reported in the United States Virgin Islands. Effects were most severe in Puerto Rico, where some areas experienced more than 12 inches (300 mm) of rainfall. Mudslides caused by flooding damaged roads, bridges, and houses. At 406 homes on the island were flooded, which five suffering at least moderate damage. In San Juan, slick roads caused several minor car accidents. One indirectly fatality was attributed to the storm after a man fell off his roof while attempting to remove a satellite dish. Damage on the island of Puerto Rico reached $501,000 (2000 USD). According to the Civil Defense Force of Dominican Republic, severe flooding in the northern portions of that country caused the evacuation of more than 700 people. In Haiti, squalls tore tin roofs off of numerous shanty homes and subsequently flooded a few. Rainfall in Cuba brought relief to an 8 month long drought in eastern Cuba.
Tropical Storm Ernesto
A tropical wave emerged into the Atlantic from the west coast of Africa on August 28. While tracking west-northwestward, satellite imagery indicated signs of a developing low-level circulation. Because the system formed significant deep convection and a low-level circulation, it was classified as Tropical Depression Eight at 1200 UTC on September 1. However, the National Hurricane Center did not initiate advisories until 15 hours later. Because of potentially unfavorable wind shear, only slight intensification was forecast. For much of its duration, the depression tracked west-northwestward at 14–17 mph (23–27 km/h) under the influence of a subtropical ridge to its north. Because of satellite intensity estimates of sustained winds of 40 mph (65 km/h), increased deep convection, and improvements in outflow, the depression became Tropical Storm Ernesto at 0600 UTC on September 2. As it strengthened into a tropical storm, Ernesto attained its peak intensity with winds of 40 mph (65 km/h) and a minimum pressure of 1,008 mbar (29.8 inHg). Because of vertical shear, the low-level circulation did not become well-defined. Because convection was being sheared away from the center, the National Hurricane Center noted the possibility of Ernesto weakening back to a tropical depression, though forecasts indicated otherwise. Later that day, no significant change in intensity was predicted, as persistent wind shear seemed to be weakening Ernesto, though the SHIPS and GFDL computer models called for significant strengthening. Although deep convection re-developed near the center early on September 3, no intensification occurred. At 1800 UTC on September 3, Ernesto weakened back to a tropical depression. Six hours later, Ernesto dissipated to the east-northeast of the Leeward Islands.
Tropical Depression Nine
A low-level trough and a cluster of convection associated with a tropical wave interacted in the Gulf of Mexico in early September 2000. A disorganized low-level center developed and thus, the system was classified as Tropical Depression Nine while located 185 miles (295 km) south of Lake Charles, Louisiana on September 7. Due to close proximity to land, the depression was unable to intensify into a tropical storm and attained a maximum wind speed of 35 mph (55 km/h). The depression weakened slightly before making landfall near Sabine Pass, Texas, with winds of 30 mph (45 km/h) on September 9. Eight hours later, the depression dissipated while barely inland. The depression brought light to moderate rainfall to Louisiana, Mississippi, Arkansas, Alabama, and Texas, though it was generally less than 3 inches (76 mm). A few areas in southern Louisiana, Mississippi, and Alabama reported precipitation in excess of 6 inches (150 mm); rainfall associated with the depression peaked at 6.70 inches (170 mm) in Buras-Triumph, Louisiana. However, the depression caused no damage or fatalities.
Main Article: Hurricane Florence (2000)
A cold front moved off the continent of North America in the first week of September 2000. It spawned a low pressure area that gradually developed into a subtropical depression at 1800 UTC on September 10, while located about 325 miles (525 km) west-southwest of Bermuda. It rapidly acquired tropical characteristics and became Tropical Depression Ten at 0600 UTC on September 11. Thereafter, the depression began to swiftly intensify, becoming Tropical Storm Florence at 1200 UTC on that day and reaching hurricane status only six hours later. Drier mid-tropospheric air weaken Florence back to a tropical storm, though it managed to re-strengthen into a hurricane later on September 12. Due to a combination of north-northwesterly shear and lower sea surface temperatures, it again weakened on September 13 and was downgraded back to a tropical storm. After moving erratically for almost five days, Florence accelerated east-northeastward in response to a short-wave trough on September 15. The storm soon began to re-intensify, becoming a hurricane early on September 16. Shortly thereafter, Florence curved northeastward and passed only 75 mph (121 km/h) west of Bermuda. However, colder sea surface temperatures weakened it back to a tropical storm September 17. Early on the following day, Florence was absorbed by an extratropical low near Newfoundland. Rip current along the East Coast of the United States caused three drowning fatalities in North Carolina. Tropical storm force winds were reported in Bermuda, though no damage occurred.
Main Article: Hurricane Gordon (2000)
A tropical wave existed the west coast of Africa on September 4 and tracked westward across the Atlantic Ocean with minimal organization for four days. After slowly developing convection between September 8 and September 14, an Air Force Reserve reconnaissance aircraft reported a closed circulation. As a result, the system was classified as Tropical Depression Eleven just offshore Quintana Roo. Shortly thereafter, the depression made landfall in Quintana Roo. On September 15, the system emerged into the Gulf of Mexico. Due to warm sea surface temperatures, the depression strengthened into Tropical Storm Gordon on the following day and further to hurricane intensity on September 17 while tracking northeastward. However, vertical wind shear and dry air entrainment weakened Gordon back to a tropical storm later that day. At 0300 UTC on September 18, Gordon made landfall near Cedar Key, Florida with winds of 65 mph (100 km/h). Gordon rapidly weakened inland and was only a tropical depression when it was absorbed by a frontal system over Georgia about 15 hours later. While passing through the Lesser Antilles, the precursor tropical wave caused locally heavy rainfall and wind gusts between 29 and 35 mph (47 and 56 km/h). Shortly before developing into a tropical cyclone, flooding in mountainous areas of Guatemala caused 23 fatalities. In its early stages, Gordon produced locally heavy rainfall in Cuba and the Yucatan Peninsula. The storm produced abnormally high tides along the west coast of Florida, which caused widespread, but minor coastal flooding. At least 65 homes and businesses were flooded, while numerous coastal roads, including Bayshore Boulevard and the Courtney Campbell Causeway, were closed due to water inundation. One fatality occurred near Pensacola, after a surfer drowned in rough seas. Strong winds in the state caused minor to moderate damage to houses, businesses, power lines, and trees. Two tornadoes in Southwest Florida extensively damaged 2 condominiums and at least 24 houses. A third tornado along the east coast of Central Florida caused minimal damage to trees and roofs. Minor flooding occurred in some areas due to rainfall reaching 9.48 inches (241 mm) in Mayo. In North Carolina, flooding caused two indirect fatalities when a car lost control and crashed into a tractor trailer. In other states, light rainfall caused mostly minor effects. Overall, Gordon was responsible for $10.8 million (2000 USD) in damage.
Tropical Storm Helene
Main Article: Tropical Storm Helene (2000)
A tropical wave emerged into the Atlantic from the west coast of Africa on September 10 and gradually developed into Tropical Depression Twelve on September 15, while located more than 600 miles (970 km) east of the Leeward Islands. It did not intensify further and instead degenerated back to a tropical wave on the following day. The remnants continued westward and crossed the Leeward Islands on September 17. Late on September 19, the remnants redeveloped into Tropical Depression Twelve near Grand Cayman. At around 1200 UTC on September 20, the depression crossed near the western tip of Cuba. Once in the Gulf of Mexico, the depression began strengthening, and became Tropical Storm Helene at early on September 21, while tracking northward. Later that day, Helene peaked with winds of 70 mph (110 km/h), though due to increasing wind shear, the storm soon began to weaken. At 1200 UTC on September 22, Helene made landfall near Fort Walton Beach, Florida with winds of 40 mph (65 km/h). Although the storm weakened slightly over land, it later began re-strengthening and became a tropical storm over North Carolina late on September 23. After re-emerging into the Atlantic Ocean, Helene once again re-intensified to near hurricane status, though the storm was absorbed by a cold front on September 26, while east-southeast of Newfoundland. The remnant tropical wave produced strong winds and flooding in the Lesser Antilles. Effects were the worst in Puerto Rico, where flash flooding and mudslides destroyed one houses and damaged at least 100 others. In addition, a bridge was also destroyed and many other roads were impassable due to flooding. Impact in Cuba, Jamaica, and Hispaniola is unknown. A combination of gusty winds, locally heavy rainfall, and a few tornadoes in the Florida Panhandle caused about 5,000 power outages, damaged more than 220 homes, and destroyed 2 houses and 4 mobile homes. Heavy rainfall caused the Sopchoppy River to exceed its banks, flooding nearby houses. Outside of Florida, effects were most severe in South Carolina, where rainfall in excess of 9 inches (230 mm) fell, and a tornado caused one fatality, six injuries, and damaged 12 houses. The other death in the state occurred when a car hydroplaned and crashed into a tree, which killed the driver. Throughout its path, Helene caused slightly more than $16 million (2000 USD) in damage.
Main Article: Hurricane Isaac (2000)
A rather well-defined tropical wave emerged into the Atlantic from the west coast of Africa on September 20. The cloud pattern quickly became better-defined, and developed into Tropical Depression Thirteen on September 21 while centered south of Cape Verde. The depression quickly intensified due to low wind shear and became Tropical Storm Isaac early on September 22 as it headed west-northwestward. Isaac continued to strengthen and was upgraded to a hurricane on September 23. Soon thereafter, Isaac rapidly intensified and reached a preliminary peak with winds of 120 mph (200 km/h). However, the structure of the storm became less organized, possibly due to slightly cooler SST's and increased wind shear. By 1200 UTC on September 26, Isaac ceased weakening after winds dropped to 85 mph (140 km/h). Later that day, the storm began to re-organize after wind shear decreased, and began to re-strengthen on September 27. On September 28, Isaac peaked as a low-end Category 4 hurricane with winds of 140 mph (220 km/h). Following its peak intensity, Isaac began to weaken immediately thereafter, while turning north-northwestward. Eventually, the storm turned northward before re-curving north-northeastward. Further weakening occurred after Isaac moved over decreasing SST's and dropped down to Category 1 intensity by September 30 while accelerating northeastward. On October 1, Isaac was downgraded to a tropical storm shortly before transitioning into extratropical later that same day. The extratropical remnants affected the British Isles between October 3 and October 4. Minimal impact was reported from Isaac. One fatality occurred when a passenger drowned after his boat capsized due to large waves produced by Isaac offshore Long Island, New York.
Main Article: Hurricane Joyce (2000)
A poorly organized tropical wave emerged into the Atlantic from the west coast of Africa on September 22. Over the next three days, the system tracked westward and slowly began to develop a closed circulation. By September 25, the National Hurricane Center initiated advisories. Convection became further organized, and the depression continued to intensity. Twelve hours after becoming a cyclone, the depression was upgraded to Tropical Storm Joyce early on September 26. Joyce continued to strengthen and was upgraded to a hurricane by September 27. On the following day, a pinhole eye appeared, and shortly thereafter, Joyce peaked as a strong Category 1 hurricane with winds of 90 mph (150 km/h) on September 28. However, wind shear and a possible intrusion of dry air caused Joyce to become disorganized and weaken. Late on September 29, Joyce was downgraded to a tropical storm while centered well east of the Lesser Antilles. Though it was always predicted to re-intensify, Joyce continued to weaken and became a tropical depression on October 1 while crossing through the southern Windward Islands. Early on the following day, Joyce unexpectedly degenerated back into an open tropical wave over the southeast Caribbean Sea. The remnants were monitored for regeneration, but never developed back into a tropical cyclone. Overall, impact from Joyce was minimal, limited to mainly rainfall and near-tropical storm force winds in Trinidad and Tobago and Barbados. The remnants of Joyce also caused similar effects on the ABC islands and Dominican Republic, which resulted in minor damage.
Main Article: Hurricane Keith
A tropical wave emerged off the west coast of Africa on September 16. The system uneventfully crossed the Atlantic and Caribbean, before developing into Tropical Depression Fifteen while near Honduras on September 28. The depression gradually strengthened, and became Tropical Storm Keith on the following day. As the storm tracked westward, it continued to intensify and was upgraded to a hurricane on September 30. Shortly thereafter, Keith began to rapidly deepen and peaked as a 140 mph (220 km/h) Category 4 hurricane less than 24 hours later. Keith then began to meander erratically offshore of Belize, which significantly weakened the storm due to land interaction. By late on October 2, Keith made landfall in Ambergris Caye, Belize as a minimal hurricane. It quickly weakened to a tropical storm, before another landfall occurred near Belize City early on the following day. While moving inland over the Yucatán Peninsula, Keith weakened further, and was downgraded to a tropical depression before emerging into the Gulf of Mexico on October 4. Once in the Gulf of Mexico, Keith began to re-strengthen and was upgraded to a tropical storm later that day, and a hurricane on the following day. By late on October 5, Keith made its third and final landfall near Tampico, Tamaulipas, Mexico as a moderately strong Category 1 hurricane. The storm quickly weakened inland and dissipated as a tropical cyclone by 24 hours after landfall. Keith brought heavy rainfall to several countries in Central America, which resulted in extensive flooding, especially in Belize and Mexico. In Guatemala, the storm flooded 10 towns, and caused one fatality. Similarly, one fatality also occurred in El Salvador, and at least 300 people were affected by flooding in that country. Thirteen communities in Nicaragua were completely isolated after Keith made roads impassable. Twelve deaths were reported in Nicaragua, all of which were flood-related. Five people were presumed dead in Honduras after an aircraft disappeared near Roatán; one other fatality occurred due to flooding. The storm brought torrential rainfall to Belize, with many areas reporting at least 10 inches (250 mm) of rain, while highest reported amount of precipitation was 32.67 inches (830 mm) in Belize City. In Belize, a village reported that only 12 houses remained, while elsewhere in the country, at least 60 homes were destroyed or damaged; several houses in Belize City suffered minor roof damage. At least 19 people were killed in Belize and damages totaled to $280 million (2000 USD). Heavy rainfall also occurred in Mexico, especially in the states of Nuevo León and Tamaulipas. Flooding by Keith caused several mudslides and a few rivers reached historic levels. Throughout Mexico, at least 460 houses were damage or destroyed and other losses in infrastructure occurred. In addition, one person drowned due to heavy rainfall. Damages incurred in associated with Keith in Mexico totaled approximately $365.9 million (2000 MXN, $38.7 million 2000 USD). Overall, Keith was responsible for 40 deaths and $319 million (2000 USD) in damage.
Tropical Storm Leslie
Main Article: Tropical Storm Leslie (2000)
A tropical wave, which likely spawned Hurricane Isaac, entered the eastern Caribbean Sea on September 27. The system slowly organized as it tracked westward and later moved to the north-northwest around Hurricane Keith. Eventually, it moved northward into the Gulf of Mexico and the Straits of Florida. The system interacted with a frontal boundary as it crossed Florida on October 3 and October 4, which caused torrential rainfall. While crossing the state, satellite imagery indicated that the system developed a circulation near Orlando. Because of its structure, the system was initially classified as a subtropical depression starting at 1200 UTC on October 4. About six hours later, the subtropical depression emerged into the Atlantic and low-level circulation gradually moved toward the deep convection while tracking just north of due east. By 1200 UTC on October 5, the subtropical depression was reclassified as Tropical Storm Leslie. While fully tropical, Leslie strengthened slightly and peaked with winds of 45 mph (75 km/h), though it soon began interacting with a cold front, and by late on October 7, it transitioned into an extratropical cyclone while located northwest of Bermuda. The system dropped heavy rainfall in Cuba, peaking at 8.25 inches (210 mm) in the Havana Province. While the precursor crossed Florida, it produced torrential rainfall across southern Florida, especially in the Miami metropolitan area. In Miami-Dade County alone, 1,005 houses were destroyed, 1,358 were severely damaged, and 3,443 had minor damage. Throughout the state, at least 93,000 homes were flooded. Electrical stations were also damaged by floods, leaving more than 27,000 people without power. Extensive agricultural damage occurred, with 40,000 acres (160 km²) of farmland inundated by water. Overall, the precursor system of Leslie resulted in about $950 million (2000 USD) in damage, slightly more than half of that figure was agriculture related. Additionally, three fatalities occurred, two of which due to drowning, while the third was a man that fell while attempting to unclog a roof drain. The remnants of Leslie caused near tropical storm force winds and waves up to 16 feet (4.9 m) in Newfoundland, though damage in the region was minimal.
Main Article: Hurricane Michael (2000)
A low pressure system developed after detaching from a cold front while between Florida and Bermuda. The low pressure area slowly formed a circulation and began to deepen on October 14 as it drifted north-northeastward. By October 15, the system developed into a subtropical depression while centered about midway between Florida and Bermuda. Later that day, satellite classifications using the Hebert-Poteat technique indicated that the subtropical depression had strengthened into a subtropical storm, and it was upgraded at 0000 UTC on October 16. Due to SST's in excess of 82 °F (28 °C), the subtropical storm developed persistent convection near the low-level center and it slowly acquired tropical characteristics. By 0000 UTC on October 17, the subtropical storm was re-classified as Tropical Storm Michael. Three hours later, the National Hurricane Center began advisories on Michael, though initially it was erroneously classified as Tropical Depression Seventeen. Although Michael was predicted intensify modestly, it rapidly strengthened, and became a hurricane later on October 17. Michael fluctuated slightly in intensity while tracking over an area of decreasing SST's. However, another brief period of rapid intensification occurred due to baroclinic effects, and Michael peaked as a minimal Category 2 hurricane. Shortly thereafter, Michael transitioned into an extratropical cyclone before making landfall near Harbour Breton, Newfoundland. Throughout Newfoundland, Michael and the remnant extratropical cyclone produced high winds, which tore off roofs, ripped off roof shingles, caused sporadic power outages, shattered windows, and uprooted trees in a few communities. Precipitation produced by the storm was light and peaked at 3.77 inches (96 mm) in North Mountain, Nova Scotia. Michael also produced rainfall in Maine and Bermuda. There were no damage figures available, though damage was considered to be relatively light.
Tropical Storm Nadine
In mid-October, a strong upper-level trough and a tropical wave interacted while located in the central Atlantic. The system moved slowly westward and convection began increasing. By October 19, the system became stationary and developed a surface circulation. Later that day, Tropical Depression Eighteen developed about 690 miles (1,110 km) southeast of Bermuda. Initially, the depression lacked a well-defined center, though a broad circulation was evident. The depression tracked slowly northward and then northeastward around a subtropical ridge and ahead of a cold front. As wind shear decreased, convective activity became better organized on October 20. By 1200 UTC on that day, the depression was upgraded to Tropical Storm Nadine. Although it was strengthening, QuikSCAT suggested that the low-level circulation was falling apart, as it appeared to be merging with the cold front. At 0000 UTC on October 21, Nadine attained its peak intensity with winds of 60 mph (95 km/h) and a minimum barometric pressure of 999 mbar (29.5 inHg). Around the time of peak intensity, a possible eye-like feature and an impressive outflow were observed on satellite imagery. As a result, the National Hurricane Center noted the possibility, but did not exclusively forecast Nadine to strengthen into a hurricane. However, shortly thereafter, wind shear increased and the storm resembled a frontal wave and appeared to possibly be interacting with the cold front. The cloud pattern then became ragged, while the low-level circulation moved toward the southern edge of the deep convection. By 0000 UTC on October 22, Nadine transitioned into an extratropical cyclone and merged with a frontal low about 18 hours later.
Unnamed Subtropical Storm
On October 25, an extratropical low pressure system formed to the east of the Turks and Caicos Islands. It moved northwestward and gradually intensified, and by 1800 UTC the system transitioned into a subtropical storm. It turned to the north and later to the northeast. A burst of convection near the center allowed the storm to attain peak winds of 65 mph (105 km/h); due to its forward motion, it is possible the surface winds reached as high as 85 mph (135 km/h). An approaching cold front caused the storm to become extratropical on October 29, and later that day a larger extratropical storm absorbed the previously subtropical storm near Nova Scotia. The Marine Prediction Center issued some marine gale and storm warnings offshore, while the National Weather Service issued gale warnings for coastal North Carolina. It was not designated as a subtropical cyclone operationally. The storm produced tropical storm force winds in portions of Atlantic Canada, although it was associated with the larger extratropical storm at the time. Several ships also recorded tropical storm force winds, one of which recorded peak winds of 53 mph (85 km/h).
The following names were used for system that attained at least tropical storm intensity within the Atlantic basin in the year 2000. Although this was the same list used for the 1994 Atlantic hurricane season, storms were named Joyce, Leslie, Michael, and Nadine for the first time in 2000 due to inactivity in the former seasons.
At their meeting in the spring of 2001, the World Meteorological Organization retired the name Keith from the list above due to its high impact and replaced it Kirk for use in the 2006 Atlantic hurricane season. The remaining storm names were re-listed for the 2006 season.
