The central pressure rapidly dropped 54 mbar (1.65 inHg) from 0000 to 0600 UTC, and at 0800 UTC, a Hurricane Hunters flight recorded a minimum central pressure of 884 mbar (26.10 inHg) in a dropsonde near the center of the extremely small eye. Wilma’s deepening rate over the northwestern Caribbean Sea, from late on 18 October to early on 19 October, was incredible. showing daily rainfall from this cyclone as of 1200 UTC, or 8 a.m. EDT. [1] Early on October 24, Wilma attained major hurricane status while located about 120 miles (190 km) west-southwest of Key West, Florida. [32] By 1117 UTC on October 25, the center was located to the northwest of the primary convection as cold air from the southwest entrained the circulation. On the 20th, Wilma weakened slightly and turned northwest toward the northeast Yucatan peninsula. [30] Early on October 25, the hurricane reached a secondary peak intensity of 125 mph (201 km/h) while located about 340 miles (550 km) east of Jacksonville, Florida. estimated 882 mb...while its very small eye was centered about 365, southeast of Cozumel. By late on October 15, the system was sufficiently organized for the National Hurricane Center to designate it as Tropical Depression Twenty-Four. [1] At the time, the pressure measured 892 mbar (26.34 inHg), the second-lowest known pressure for a Category 4 hurricane (Super Typhoon Judy had an 887 mb pressure at peak intensity), and Wilma retained the large eyewall as it turned northwestward. At the time these images were taken, Wilma was drifting very slowly to the northwest towards Cozumel, Mexico. Hurricane Wilma formed in the Carribean as a tropical depression on October 15, 2005, becoming the 21st named storm of the 2005 hurricane season, the most active on record save for 1933, which also had 21 named storms. The path of Hurricane Wilma crossed through the ranges of many North American migratory birds, most notably the Chimney Swift (Chaetura pelagica) which annually migrates from as far north as Canadian Maritime provinces south to the Yucatan Peninsula. Environmental conditions remained favorable,[1] with the eye becoming more distinct early on October 21. Wilma was a classic October hurricane which struck South Florida as a Category 3 hurricane on October 24th, 2005. Initially, the center of circulation was broad without a defined inner core; forecaster Lixion Avila remarked, "The area of minimum pressure could [have been] anywhere within 60 miles (97 km) of its [initial advisory position]." Central America, Mexico, Texas. It was then that the National Hurricane Center first indicated that it was possible for a tropical depression to develop in the area. Uploaded originally because the file wouldn't play on my computer. National Hurricane Center forecaster James Franklin remarked, "Confidence at the later ranges [of the forecast track] was unusually low", due to wide divergences between computer models. At its peak intensity, the eye of Wilma was about 2.3 miles (3.7 km) in diameter, the smallest known eye in an Atlantic hurricane. [14] It continued to intensify, and at 1200 UTC on October 18, Wilma attained hurricane status while located about 225 miles (362 km) south-southeast of Grand Cayman. Less than a week after Wilma formed, Tropical Storm Alpha struck Hispaniola and caused additional deadly floods in Haiti. [16] It is estimated by Dr. Eric Uhlhorn of NOAA's Hurricane Research Division that the winds may have peaked at between 209 and 229 mph rounded to 210 and 230 mph respectively following that Hurricane Hunter mission. [18], Shortly after peaking in intensity, the coldest cloud tops surrounding the eye warmed slightly and an outer eyewall began to develop, signifying an eyewall replacement cycle was occurring. The storm was expected to enter the Gulf of Mexico as a weaker hurricane before making landfall along the west coast of Florida. A large area of disturbed weather developed across much of the Caribbean Sea and gradually organized to the southeast of Jamaica. [9], By early on October 17, the outer rainbands, which had previously dominated the structure of the cyclone, dissipated, while deep convection developed near and to the south of the center. [23] At about 2145 UTC on October 21, Wilma made landfall on the island of Cozumel with winds of 150 mph (240 km/h). The latest: Hurricane Laura has made landfall near Cameron, Louisiana, as a Category 4 storm. Description: This map created by FCIT shows the track of hurricane Wilma in 2005. After reaching tropical storm intensity on October 17 and then hurricane status on October 18, the system explosively deepened, peaking as the strongest tropical cyclone ever recorded in the Atlantic basin. [24], On October 22, the mid-level ridge to the north of Wilma essentially dissipated, leaving the hurricane drifting northward across the northeastern Yucatán Peninsula. Shortly after exiting the Florida coastline, Wilma began to re-intensify,[1] believed to be due to a reduction of friction of the eyewall and warm waters of the Gulf Stream. [8] Continued reconnaissance flights reported peak winds of about 30 mph (48 km/h). [11], The storm continued to the southwest while deep convection persisted near the center. This is the lowest pressure on record for a hurricane. Upon becoming a tropical storm, the National Hurricane Center predicted Wilma to track west-northwestward, reaching winds of 105 mph (169 km/h) before striking the northeastern portion of the Yucatán Peninsula. Hurricane Wilma was the most intense tropical cyclone in the Atlantic basin on record in terms of minimum barometric pressure, with an atmospheric pressure of 882 hPa (mbar, 26.05 inHg). Part of the 2018 Pacific hurricane season. [29] Despite wind shear values of about 30 mph (48 km/h), Wilma strengthened further to reach winds of 125 mph (201 km/h). WILMA IS A LARGE HURRICANE AND TROPICAL STORM FORCE WINDS WILL REACH THE FLORIDA PENINSULA WELL BEFORE THE EYE MAKES LANDFALL. Over the period from 2310 UTC to 0433 UTC, the central pressure fell from 954 mb to 901 mb, which is a deepening rate of 9.9 mb per hour. [19] Early on October 20 the hurricane weakened to Category 4 status after the small, inner eye dissipated and the 45-mile (72 km) wide outer eyewall became the dominant eye. Hurricane Wilma was the most intense tropical cyclone in the Atlantic basin on record in terms of minimum barometric pressure, with an atmospheric pressure of 882 hPa (mbar, 26.05 inHg). 2 months ago. [10] Deep convection continued to develop to the south of the center, and the depression intensified into Tropical Storm Wilma at 0600 UTC on October 17, while located about 200 miles (320 km) southeast of Grand Cayman. The storm cut communications between Les Cayes and Tiburon.

Wilma slowly weakened as it drifted over the northeast Yucatan. The system was enhanced by diffluence from an upper-level low across the southwestern Atlantic. Hurricane Wilma rapidly intensified in the Caribbean, growing from a tropical storm with winds of 69 mph on Oct. 18 to a Category 5 hurricane with winds of 172 mph on Oct. 19. This was due to the depression being located within an environment very conducive for development, specifically low amounts of wind shear and very warm water temperatures. For several days in its formative stages, Wilma's outer rainbands dropped heavy rainfall in Haiti and as far east as the Dominican Republic. [5] By late on October 15, the surface circulation became defined well enough, with sufficiently organized deep convection, for the National Hurricane Center to designate the system as Tropical Depression Twenty-Four while it was located about 220 miles (350 km) east-southeast of Grand Cayman. By October 26, it transitioned into an extratropical cyclone, and the next day, the remnants of Wilma were absorbed by another extratropical storm over Atlantic Canada. Wilma formed from a large area of distubed weather that stretched across, low pressure system gradually became defined, depression developed about 215 miles southeast of Grand Cayman, the 15th. [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. Wilma was able to retain its strength because large eyes in tropical cyclones are more stable and more resistant to vertical wind shear. [33] The remaining convection continued to diminish, and by late on October 25 Wilma transitioned into an extratropical cyclone while located about 230 miles (370 km) southeast of Halifax, Nova Scotia, and still at Category 1 intensity. Wilma developed in the Caribbean Sea just southwest of Jamaica on October 15 from a large area of disturbed weather. [1], Hurricane Wilma crossed the Florida peninsula in about 4.5 hours while continuing to accelerate northeastward, and emerged into the Atlantic Ocean as a weakened 110 mph (180 km/h) hurricane near Jupiter. [28], A powerful eastward-moving mid-level trough across the central United States turned the hurricane northeastward and caused it to gradually accelerate. Vertical wind shear increased as strong upper-level southwesterly flow increased, though in spite of the shear Wilma continued to intensify. Tropical Storm Irma formed in the far eastern Atlantic Ocean, just west of the Cape Verde Islands, on the morning of August 30 th.Over the following 30 hours Irma intensified into a major hurricane with highest sustained winds of 115 MPH, a category-3 storm on the Saffir-Simpson Hurricane Wind Scale. [1] Operationally, the peak intensity was estimated at 175 mph (282 km/h). [1] Convection increased and became slightly better organized, though upper-level wind shear initially prevented development. Initially, the tropical depression was forecast to drift west-southwestward before turning to the north; within five days of the forecast's issuance, the system was predicted to be located about 80 miles (130 km) south of the Isle of Youth as a 105 mph (169 km/h) hurricane. Wilma weakened over the Yucatán Peninsula, and reached the southern Gulf of Mexico before accelerating northeastward. From October 18, and through the following day, Wilma underwent explosive deepening over the open waters of the Caribbean; in a 30-hour period, the system's central atmospheric pressure dropped from 982 mbar (29.00 inHg) to the record-low value of 882 mbar (26.05 inHg), while the winds increased to 185 mph (298 km/h). Hurricane Wilma remained a powerful Category 4 storm when the Moderate Resolution Imaging Spectroradiometer on NASA’s Terra satellite took this image at 12:25 p.m. Eastern Daylight Time, on Friday, October 21, 2005.Two days earlier, Wilma had surged from tropical storm to Category 5 hurricane in record time. This small eye was surrounded by a ring of deep convection, with cloud-top temperatures of about â125 °F (â87 °C). The hurricane's path and size spread its effects across an enormous swath of the state, from floods in the Keys to tornadoes on Central Florida's Space Coast. Wilma's destructive journey began in the second week of October 2005. Early on Wednesday, Wilma became the most intense hurricane ever recorded in the Atlantic. About 75,000 people in northeastern Mexico evacuated the path of the storm. Hurricane Delta followed an eerily similar development path to Wilma in early October, rapidly intensifying in a 24-hour stretch only to eventually batter the Yucatan Peninsula. [15], 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 165 mph (266 km/h), making Wilma a dangerous Category 5 storm on the Saffir-Simpson Hurricane Scale. [17] At the time of its peak intensity, hurricane-force winds extended only 50 miles (80 km) from the small center of Wilma, with tropical storm force winds extending only about 160 miles (260 km). [1] As the hurricane moved further inland, the eye became cloud-filled as the deepest convection began to warm, and the winds gradually weakened during its passage over land. This was due to unusually low pressures across the region, which resulted in a lesser pressure gradient and thus lighter winds. [1], The depression tracked slowly westward, a motion due to weak steering currents caused by a high pressure area to its north across the Gulf of Mexico. Maps: Tracking Hurricane Irma’s Path Over Florida UPDATED 5:00 PM ET, SEPT. 11, 2017 Hurricane Irma lost strength as it swept across Florida, and was downgraded to … Hurricane Wilma affected parts of northeast Mexico that had been struck by Hurricane Stan just two weeks earlier, as well as Hurricane Emily in July. [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. Despite increasing amounts of vertical wind shear, the hurricane re-strengthened to hit Cape Romano, Florida, as a major hurricane. As the dropsonde did not reach the calm winds in the center, the pressure was estimated at 882 mbar (26.05 inHg), the lowest pressure in an Atlantic hurricane on record. [26] Upon reaching open waters, Reconnaissance Aircraft reported the remains of an inner eyewall and an outer eyewall oscillating between 70 and 90 miles (110 and 140 km) in diameter. A large area of disturbed weather developed across much of the Caribbean Sea and gradually organized to the southeast of Jamaica. Initially, development was slow due to its large size, though convection steadily organized. [1] The system continued to organize, with the National Hurricane Center remarking the system could ultimately become a hurricane. Hurricane Willa was a powerful tropical cyclone that brought torrential rains and destructive winds to southwestern Mexico, particularly the states of Sinaloa and Nayarit, during late-October 2018. ISS012-E-5235 (19 Oct. 2005) --- This image of Hurricane Wilma was taken at 8:22 a.m. CDT Wednesday, Oct. 19, by the crew aboard NASA's international space station as the complex flew 222 miles above the storm. It was the fastest rate of intensification in the Caribbean since Hurricane Wilma in 2005, when that storm went from 75 mph to 185 mph in just 24 hours time. The rains triggered river flooding and landslides in Haiti, killing 12 people, and forcing 300 residents into shelters. The center of Wilma then drifted over the far northeastern tip of the Yucatan Peninsula delivering torrential rains and strong winds. Weather Underground provides tracking maps, 5-day forecasts, computer models, satellite imagery and detailed storm statistics for tracking and forecasting Major Hurricane Wilma … Convection deepened around the eyewalls,[27] and the inner core of convection, which had previously become disrupted over land, became slightly better defined. Hurricane Wilma moved across the extreme southeastern Gulf of Mexico and southern Florida peninsula during the morning hours of Monday, 24 October 2005, bringing hurricane-force winds to … It weakened slightly as it approached Florida, and made landfall at Cape Romano with winds of 120 mph (190 km/h) at around 1030 UTC on October 24. [25] About 26 hours after making landfall on Cozumel, Wilma emerged into the southern Gulf of Mexico near Cabo Catoche with winds of about 100 mph (160 km/h). October 24, 2005: 11 Years since Hurricane Wilma … Hurricane Matthew Could Make a U-Turn and Hit Florida Twice.

[2][3], Later on October 14, the system became much better defined, with increasingly organized shower and thunderstorm activity, as conditions in the upper levels of the atmosphere became significantly more favorable. [1] By October 13, a broad area of low pressure developed and persisted about 150 miles (240 km) southeast of Jamaica,[2] possibly aided by the passage of tropical waves through the area at the time. The storm's 882 millibars of pressure broke the record low of 888 set by Hurricane … However, the National Hurricane Center noted in the first advisory on the depression that there were "all indications that there could a dangerous hurricane in the northwestern Caribbean Sea in 3 to 5 days." Convection continued to develop near the center and became much more symmetrical. The The TRMM satellite is one of many satellites monitoring hurricanes and typhoons. [1][20] Initially, the hurricane was forecast to re-intensify into a Category 5 hurricane,[21] with one forecast predicting it to make landfall on the Yucatán Peninsula with winds of 165 mph (266 km/h),[22] though Wilma remained a strong Category 4 hurricane as it tracked northwestward. Wilma became a hurricane and began a west-northwestward motion on the 18th. After the inner eye dissipated due to an eyewall replacement cycle, Hurricane Wilma weakened to Category 4 status, and on October 21, it made landfall on Cozumel and on the Mexican mainland with winds of about 150 mph (240 km/h). The hurricane again re-intensified before cold air and wind shear penetrated the inner core of convection. [4] Dvorak classifications were initiated on October 15. It gradually became better organized, with the large 50 miles (80 km) eye becoming very distinct on satellite and radar imagery. On October 18, 2005, Wilma went from tropical storm to hurricane status. [1] The overall cloud pattern began to deteriorate, with the eye becoming less distinct and the convection less symmetric. A vigorous cold front associated with the mid-level trough moved across the area to the west of Wilma, yet the cooler and drier air behind the front could not fully penetrate the inner core of the hurricane to weaken it. [1] The eye continued to contract to a diameter of about 2 nautical miles (3.7 km), the smallest known eye in an Atlantic hurricane, and at 1200 UTC on October 19, Wilma attained peak winds of 185 mph (298 km/h). During the second week of October, an unusually large, monsoon-like lower-level circulation and a broad area of disturbed weather developed over much of the Caribbean Sea. At the time, Wilma was the strongest Atlantic hurricane in history, with winds near 175 miles per hour. [1] In the span of just 24 hours, Wilma had intensified from a 70 mph (110 km/h) tropical storm to a 175 mph (282 km/h) Category 5 hurricane, an unprecedented event for an Atlantic hurricane. The weakening extratropical remnant turned to the east-northeast before being absorbed by another extratropical storm over Atlantic Canada on October 27. Ahead of Wilma's landfall, workers trimmed trees near power lines and placed notices on roads. Computer models predicted steady strengthening as the depression tracked westward before turning to the north. Wilma's destructive journey began in the second week of October 2005. It weakened slightly as it continued northwestward, and struck the Mexican mainland near Puerto Morelos, Quintana Roo, at 0330 UTC on October 22, with winds of 135 mph (217 km/h)[1] and gusts of up to 170 mph (270 km/h). On October 21, 2005, Wilma slowly crossed over Cozumel as a strong Category 4 hurricane with sustained winds reported at up to 230 kilometers per hour (144 miles per hour) by the National Hurricane Center (NHC). Wilma developed from a tropical depression near Jamaica, a typical source region for October tropical cyclones, on the afternoon of October 15, 2005. The depression drifted southwestward, and under favorable conditions, it strengthened into Tropical Storm Wilma on October 17. The tropical cyclone moved erratically southwestward for two. [1] Shortly after reaching hurricane strength, the hurricane began undergoing explosive deepening, after the development of a "pinhole" eye 9 miles (14 km) in diameter. Below is a calendar [1], Steering currents remained weak, though a series of troughs eroded the high pressure system across the Gulf of Mexico, resulting in a turn towards the north-northwest. Damage in the country totaled around $500,000 (2005 USD). [13], Tropical Storm Wilma began to turn to the west-northwest on October 18,[1] during which the storm developed a small, intermittent and ragged eye feature. Wilma weakened as it quickly crossed the state, and entered the Atlantic Ocean near Jupiter, Florida. [16] By late on October 19, the winds in Hurricane Wilma decreased to 160 mph (260 km/h) as the inner 5-mile (8 km) wide eye weakened and the wind field expanded. [31], Shortly after its secondary peak intensity, the wind shear, combined with its rapid forward motion of 50 mph (80 km/h), resulted in a steady weakening trend. Hurricane Wilma was the 25 th tropical cyclone and 12 th hurricane of the hyperactive 2005 season, and the fifth tropical cyclone in as many months to have a significant impact on the Florida Keys. Of the intensity models, the Geophysical Fluid Dynamics Laboratory predicted an intensity of 135 mph (217 km/h) within 36 hours, with other forecasts being more conservative in their predictions. ACCOMPANIED BY THE STRONGEST WINDS... WILL REACH THE SOUTHWESTERN COAST OF FLORIDA ABOUT 2 HOURS BEFORE THE CENTER OF THE … Read more about Hurricane Wilma in The Post’s 10th anniversary story about the unprecedented tropical cyclone here. Detailed Meteorological Write-up on Hurricane Irma. [1] During the time, the large circulation of Wilma absorbed the much smaller Tropical Depression Alpha over the Bahamas. Surface buoy reports indicated that, due to its large size, the system failed to strengthen beyond tropical depression status, even though it received tropical storm strength Dvorak classifications from The National Hurricane Center's Tropical Analysis and Forecast Branch and the National Oceanic and Atmospheric Administration's Satellite Analysis Branch. The pressure continued to fall as the Hurricane Hunters left the hurricane, and it is possible the pressure was slightly lower. On the 21st, the hurricane made landfall over Cozumel, and by early the 22nd it made landfall over the northeast Yucatan peninsula; both landfalls were at category 4 intensity. [6], As Tropical Depression Twenty-Four drifted southwestward, it steadily organized; by early on October 16, rainbands began to gradually consolidate with well-established outflow, and a large upper-level anticyclone developed over the depression. Wilma at landfall in southwestern Florida has been set at 105 kt. The legend shows the different categories of hurricanes as follows: Cat 5 (dark red), Cat 4 (red), Cat 3 (orange), Cat 2 (yellow), Cat 1 (green), tropical storm (teal), tropical depression (blue), and lower category (purple). By late on October 15, the system was sufficiently organized for the National Hurricane Centerto designate it as Tropical Depre… It has since weakened to a Category 2, with winds of 110 mph. Areas affected. The system drifted westward, and early on October 14 the convection became more concentrated and a little better organized as upper-level wind shear lessened slightly. Hurricane Wilma was the most intense tropical cyclone ever recorded in terms of pressure in the Atlantic Ocean.It destroyed parts of the Yucatán Peninsula and southern Florida during October in the 2005 Atlantic hurricane season.Wilma broke several records for both strength and seasonal activity.
