Tropical Storm Sebastien was the twentieth cyclone of the active 1995 Atlantic hurricane season. Sebastien originated from a tropical wave that near the coast of Africa on October 13 and moved westward toward the Caribbean Sea. The wave increased in convection and became Tropical Depression Twenty on October 20, strengthening into a tropical storm within 12 hours of formation. Sebastien encountered a tropical low off of Puerto Rico and entered some southwesterly wind shear, which stopped strengthening at Template:Convert/mph on October 23. The now-depression Sebastien made landfall in Anguilla on the morning of October 24. Sebastien soon entered a low-level flow and encountered wind shear, becoming a remnant low on October 25 near the Virgin Islands and Puerto Rico. While over that area, it produced moderate rain, but damage was minimal, and no deaths were reported.

Meteorological history

A tropical wave exited the west coast of Africa on October 13 and moved westward across the Atlantic. On October 20, shower activity increased, and it was declared a depression that day. Twelve hours after forming, the depression became Tropical Storm Sebastien.[1] It became better organized and developed good outflow.[2] Although wind shear was expected to limit intensification.[3] the storm instead intensified to a peak of 65 mph (100 km/h) late on October 22, based on a ship report.[1] Operationally, it was originally believed to be weaker.[4] At the time, most of the convection was sheared away from the center, and the storm was interacting with a low pressure area near Puerto Rico.[1] The storm was located to the northeast of the northern Leeward Islands, although it turned to the southwest along the low-level flow and into an area of increasing shear. On October 24, Sebastien weakened into a tropical depression, at which intensity it made landfall on Anguilla. The next day, the system dissipated near the U.S. Virgin Islands, although the remnants continued westward.[1]

Preparations and impact

As Tropical Storm Sebastien turned towards the Caribbean Sea on October 23, the National Hurricane Center issued a tropical storm watch for the United States Virgin Islands and the British Virgin Islands.[1] Other islands were on alert as the NHC stated that the watch area may need to be expanded.[5] Still recovering from Hurricane Marilyn less than a month ago, residents living in damaged homes reportedly evacuated their homes.[6] However, the watch was discontinued 24 hours later after the storm weakened to a tropical depression.[1] The remnants of Sebastien produced moderate rainfall across parts of Puerto Rico, peaking at Template:Convert/in in Quebradillas.[7] There was no damage in the Leeward Islands.[1]
