<P> Shortly before 06: 00 UTC on September 8, Irma made landfall on the Bahamian island Little Inagua . About three hours later, an eyewall replacement cycle caused Irma to weaken to a Category 4 hurricane, but the storm regained Category 5 status 18 hours later before making landfall in Cuba . After weakening to a Category 3 due to land interaction with Cuba, Irma reintensified into a Category 4 hurricane while crossing over the Straits of Florida . At 13: 10 UTC on September 10, Irma made landfall in Cudjoe Key, Florida with maximum sustained winds of 130 mph (215 km / h) and a central pressure of 929 hPa (27.4 inHg). Later that day, at 19: 35 UTC, Irma made landfall in Marco Island with maximum sustained winds of 115 mph (185 km / h) and a central pressure of 940 hPa (28 inHg); the Marco Island Police Department recorded a wind gust of 130 mph (215 km / h). The Naples, FL Municipal Airport measured wind gusts up to 142 mph (229 km / h). About a half an hour later, Irma made landfall in Naples at the same intensity . Irma weakened into a Category 2 storm once inland, and below hurricane intensity at 12: 00 UTC on September 11 . At 03: 00 UTC on September 12, Irma weakened to a tropical depression over the Georgia - Alabama border, and degenerated into a post-tropical low about 24 hours later north of Tupelo, Mississippi . Irma's remnants continued moving towards the northwest over the next day, before turning northward and then accelerating to the northeast on September 14 . Early on September 15, Irma's remnants began moving off the New England coastline, becoming increasingly disorganized while continuing to weaken . Later on the same day, Irma's remnants began interacting with a cold front stretching over Newfoundland . On September 16, Irma's remnant circulation collapsed, and the majority of Irma's remnant moisture was absorbed into Hurricane Jose later that day . </P> <P> Data collected by NASA showed that ocean surface temperatures in the path of Irma were above 30 ° C (86 ° F) at the time, more than enough to sustain a Category 5 hurricane . Additionally, ocean surface temperatures in areas along the Strait of Florida extended to 32 ° C (90 ° F), which could support a maximum potential intensity of 200 miles per hour (320 km / h), if ideal conditions had been met . </P> <P> Given that Irma's forecast track was along much of the Caribbean island chain, hurricane warnings were issued for the northern Leeward Islands, Puerto Rico and parts of Hispaniola on September 5 . </P> <P> On September 4, Puerto Rico declared a state of emergency . By September 6, the U.S. Federal Emergency Management Agency had deployed response teams in Puerto Rico and the United States Virgin Islands . Supplies, including food rations, medical supplies, and blankets, were pre-staged in strategic locations on the islands for distribution . </P>
