Tampa may shut down airport
In Tampa, where residents are bracing for 10 feet of dangerous storm surge, the Tampa International Airport may shut down parts of its airfield and facilities over the next day or two, airport officials announced.
The airport is in an evacuation zone, but because it’s critical infrastructure, it’s “exempt from the storm evacuation order and will stay open until a closure is necessary,” airport officials said in a statement.
It’s been 101 years since Tampa last had a direct hit from a major hurricane.

Ian weakens slightly but will regain strength overnight
Tropical Storm Ian has weakened slightly, but it is expected to not only strengthen but rapidly intensify overnight as it travels over warm waters in the Caribbean.
As of 5 p.m. ET, the storm system had maximum sustained winds of 45 mph and was moving west-northwest at 12 mph, with the center located about 220 miles away from Grand Cayman.
Dry air ahead of the storm has delayed the strengthening trend so far. But the rapid intensification is expected to occur Monday into Tuesday as the system continues across the northwestern Caribbean and closes in on western Cuba.
Over the next 24 hours, the outer bands will impact Jamaica and the Cayman Islands, bringing rounds of heavy rain, possible flash flooding and storm surge. Later Monday and into Monday night, Ian will be closing in on western Cuba and will likely bring significant wind and storm surge impacts to the region.
A hurricane warning is in effect for Grand Cayman and portions of western Cuba. A tropical storm watch has been issued for portions of western Cuba, as well as the lower Florida Keys, including Key West.
As of 5 p.m., the forecast track was nudged slightly eastward. Overall, the forecast guidance variability and uncertainty will remain high, and the track for where the storm will be from the middle to the end of the week will continue to shift over the next 24 to 48 hours.
