The take-home message: while it is too soon to rule out other possibilities, Irma has a good chance of moving northward close enough to the Florida peninsula for significant impacts to large parts of the state, potentially devastating in some areas. Irma may be moving at 10 mph for a day or more after it makes its northward turn, which will prolong the period of high winds and heavy rains within its circulation. Even if it moves along Florida’s west coast, residents on the East Coast could still receive hurricane-force winds, significant storm surge, and torrential rains of 10 - 15” or more. Depending on Irma’s track, some areas could experience 8 hours or more of hurricane-force wind and 24 hours or more of tropical-storm-force wind. The National Hurricane Center reminds us not to focus on the exact forecast track, though, especially at the longer ranges, since the average NHC track errors are about 175 and 225 miles at days 4 and 5, respectively.
