what was the lowest barometric pressure for hurricane irma
914 mbar (hPa)
title: Meteorological history of Hurricane Irma text: (285 km/h) near 18:00 UTC on September 5 – although it was operationally assessed at 185 mph (295 km/h). Early on September 6, the storm reached its minimum barometric pressure of just before 06:00 UTC, an estimate based on a dropsonde surface pressure observation and measurements from Barbuda and Saint Barthélemy. This was the lowest barometric pressure in the Atlantic since Dean in 2007. Irma made landfall along the northern coast of Barbuda around 05:45 UTC at peak strength. After crossing the island of Barbuda, the hurricane, which maintained its intensity and impressive satellite appearance, struck Saint Martin at 11:15 title: Hurricane Irma text: storm's pressure bottomed out at – this was the lowest in the Atlantic since Dean in 2007. While maintaining its intensity, Irma made successive landfalls on September 6, at 11:15 UTC on Sint Maarten, and at 16:30 UTC on Virgin Gorda, in the British Virgin Islands, all while it was at peak intensity. As the hurricane moved away from the Virgin Islands late on September 6, observations from reconnaissance flights as well as Doppler radar in San Juan, Puerto Rico, indicated an elliptical eye and double eyewalls. Late on September 6, the cyclone passed about north of Puerto Rico. Moving title: Hurricane Irma text: the northern coast of Cuba, gradual weakening ensued due to land interaction, with the eye becoming cloud-filled and the intensity falling to a high-end Category 2 storm later on September 9. After slowing down late on September 9, the hurricane turned northwestward towards Florida around the southwestern edge of the subtropical high to its northeast and a low-pressure system that was located over the continental United States. Moving over the warm waters of the Straits of Florida, Irma quickly restrengthened to a Category 4 hurricane at 06:00 UTC on September 10, as deep convection improved and the eye becoming better title: Meteorological history of Hurricane Irma text: Meteorological history of Hurricane Irma Hurricane Irma was an extremely powerful Cape Verde hurricane that caused extensive damage in the Caribbean and Florida. Lasting from late August to mid-September 2017, the storm was the strongest open-Atlantic tropical cyclone on record and the first Category 5 hurricane to strike the Leeward Islands. Classified as the ninth named storm, fourth hurricane, and second major hurricane of the hyperactive 2017 Atlantic hurricane season, Irma developed from a tropical wave near the Cape Verde Islands on August 30. Favorable conditions allowed the cyclone to become a hurricane on the following day and then rapidly title: Hurricane Irma text: at 57.7°W, it became the easternmost Atlantic hurricane of this strength on record, surpassing Hurricane David of 1979. By 00:15 UTC on September 6, Irma reached peak intensity with () winds and a minimum pressure of . This ties it with Hurricane Mitch of 1998 and Hurricane Rita of 2005 as the fifth-strongest Atlantic hurricane by wind speed. Only four other Atlantic hurricanes have been recorded with wind speeds higher than Irma: Hurricane Allen of 1980, which had maximum sustained winds of 190 mph (305 km/h), and the 1935 Labor Day hurricane, Hurricane Gilbert of 1988, and Hurricane Wilma of
