Convection continued to develop near the center and became much more symmetrical. xmlns:xsl='http://www.w3.org/1999/XSL/Transform'">. [1] Early on October 24, Wilma re-gained major hurricane status while about 120 miles (195 km) west-southwest of Key West, Florida. The meteorological history of Hurricane Wilma, the strongest tropical cyclone known in the Western Hemisphere, began in the second week of October 2005.A big weather system formed across much of the Caribbean Sea and slowly organized to the southeast of Jamaica.By late on October 15, the system was became strong for the National Hurricane Center to name it Tropical Depression Twenty-Four. Environmental conditions remained favorable,[1] with the eye becoming more distinct early on October 21. Right after becoming a tropical storm, the National Hurricane Center predicted Wilma to track west-northwestward, reaching winds of 105 mph (170 km/h) before striking the northeastern portion of the Yucatán Peninsula. It was responsible for over $29 billion in damage. [27], A powerful eastward-moving mid-level trough across the central United States turned the hurricane northeastward and caused it to gradually speed up. Its first land fall was on October 21 in Cozumel. This page was last changed on 19 February 2020, at 02:09. [3], Later on October 14, the system became much better organized, with increasingly organized shower and thunderstorm activity, as conditions in the upper levels of the atmosphere became significantly more favorable. Early on October 19, Wilma attained major hurricane status while continuing to rapidly intensify, and by 0600 UTC, the storm's maximum sustained winds increased to 170 mph (275 km/h), making Wilma a dangerous Category 5 hurricane on the Saffir-Simpson Hurricane Scale. The meteorological history of Hurricane Wilma, the strongest tropical cyclone known in the Western Hemisphere, began in the second week of October 2005. [1] Operationally, the peak intensity was estimated at 175 mph (280 km/h). The pressure continued to fall as the Hurricane Hunters left the hurricane, and it is possible the pressure was a little bit lower. [1] Convection increased and became slightly better organized, though upper-level wind shear originally stopped development. [7] Although deep convection and banding features increased, mid-level dry air from the north prevented significant organization, and the convection was split into two primary areas.

Originally, the tropical depression was forecast to drift west-southwestward before turning to the north; within 120 hours of the forecast's issuance, the system was predicted to be about 80 miles (130 km) south of the Isle of Youth as a 105 mph (170 km/h) hurricane. [1] The eye continued to contract to a diameter of about 3 miles (5 km), the smallest known eye in an Atlantic hurricane, and at 1200 UTC on October 19, Wilma reached peak winds of 185 mph (300 km/h). It weakened a little bit as it continued northwestward, and struck the Mexican mainland near Puerto Morelos at 0330 UTC on October 22, with winds of 135 mph (215 km/h)[1] and gusts of up to 170 mph (270 km/h). [1] In the span of just 24 hours, Wilma had intensified from a 70-mph (110-km/h) tropical storm to a 175-mph (280-km/h) Category 5 hurricane, an event that has never happened before for an Atlantic hurricane. Computer models predicted steady strengthening as the depression moved westward before turning to the north. javascript is enabled. [1] During the time, the large circulation of Wilma absorbed smaller Tropical Depression Alpha over the Bahamas. [18] Early on October 20 the hurricane weakened to Category 4 status after the small, inner eye dissipated and the 45 mile wide outer eyewall became the new eye. At first, the depression moved erratically and slowly in the waters between Jamaica and Central America. A big weather system formed across much of the Caribbean Sea and slowly organized to the southeast of Jamaica. [31] By 1170 UTC on October 25, the center was to the northwest of the primary convection as cold air from the southwest disturbed the circulation. On October 26, it turned into an extratropical cyclone, and the next day, the remnants of Wilma were absorbed by another extratropical storm over Atlantic Canada. The initially ill-defined system organized into a tropical depression on 15 October. [14] It continued to strength, and at 1200 UTC on October 18, Wilma strengthened into a Category 1 hurricane while about 225 miles (360 km) south-southeast of Grand Cayman. [1] The overall cloud pattern began to be disorganized, with the eye becoming less visible and the convection less symmetric. Of the intensity models, the Geophysical Fluid Dynamics Laboratory predicted an intensity of 135 mph (215 km/h) within 36 hours, with other forecasts being more conservative in their predictions. [5] By late on October 15, the surface circulation became defined well-enough, with enough organized deep convection, for the National Hurricane Center to designate the system as Tropical Depression Twenty-Four while it was about 220 miles (345 km) east-southeast of Grand Cayman.

[29] Early on October 25, the hurricane reached a secondary peak intensity of 125 mph while about 340 miles (545 km) east of Jacksonville, Florida. [12] Late on October 17, a Hurricane Hunters flight into Wilma recorded winds of 50 mph (80 km/h), but an unusually low pressure of 989 mbar (29.21 inHg), which would be more typical of a minimal hurricane. Hurricane Wilma had a complex beginning, and would go on to inflict extensive damage.
