“Irma” made landfall as a category 4 hurricane at Cudjoe Key, Florida after devastating the U.S. Virgin Islands – St John and St Thomas – as a category 5 storm.

“The Florida Keys were heavily impacted, as 25% of buildings were destroyed while 65% were significantly damaged. Severe wind and storm surge damage also occurred along the coasts of Florida and South Carolina. Jacksonville, FL and Charleston, SC received near-historic levels of storm surge causing significant coastal flooding. Irma maintained a maximum sustained wind of 185 mph for 37 hours, the longest in the satellite era. Irma also was a category 5 storm for longer than all other Atlantic hurricanes except Ivan in 2004.” — NOAA: Billion-Dollar Weather and Climate Disasters
