Tropical Depression One was the first tropical cyclone to develop during the 1990 Atlantic hurricane season. Having formed on May 26, 1990 the storm was the first tropical cyclone in the Atlantic Ocean during the 1990s. Forming out of an area of low pressure in the Western Caribbean, the storm made landfall in Cuba bringing heavy rains and winds of 30 mph (45 km/h). After being absorbed by a frontal zone the remnants of the storm brought rain to a then drought stricken Florida.

Meteorological history

Tropical Depression One formed from an area of weak low pressure located west of Jamaica, half way between the island and mainland Mexico. The low had been causing cloudiness and scattered showers over most of Jamaica on May 23 and May 24.[1] On Thursday May 24, the low was officially upgraded to a Tropical depression about 275 miles (442 km) south of Havana, Cuba with maximum sustained winds of 30 mph (45 km/h).[1][2][3]

Tropical Depression One made landfall in Cuba on May 25th with 30 mph (45 km/h) winds and heavy convection located to the east of its poorly defined center.[2] The storm proceeded towards the Florida Straits but was absorbed by a frontal zone on May 26 over the Florida Keys and its remnants moved over Florida dumping heavy rain.[2]

Preparations and impact


Jamaica was one of the first places to experience the Tropical Depression in the form of heavy rain.[1] As the storm moved toward Cuba, meteorologists predicted the storm could dump as much as ten to 15 inches of rain over parts of the island nation.[4][5] Tropical Depression One made its only landfall in Cuba bringing with it winds of 30 mph (45 km/h) and gusts of 35 mph (55 km/h).[2]


Tropical Depression One was viewed as a welcomed form of rain in Florida, a state that had been suffering from a two year drought.[4] The depression and its remnants dropped as much as 6 inches of rain in some parts of Southern Florida with the highest rainfall being reported in the everglades and south of Miami.[6] During the storm the National Weather Service issued "urban flood statements" warning of flooded streets in mainly low lying areas, especially in Dade and Broward counties.[6] Standing water on many Florida expressways caused automobile accidents, especially in Dade County where 28 accidents were reported.[6]
