At 5 am, Irma is located 40 miles SSE of Key West. Maximum sustained winds are near 130 mph, which is a category 4 hurricane. We are not expecting anymore strengthening due to increasing shear and soon land interaction. A gradual weakening is expected, but will still be a major hurricane for the next 24 hours. Irma is moving northwest at 8 mph. The core of Irma will move across the Keys during the next few hours. DO NOT GO OUTSIDE IF YOU ARE STILL IN THE KEYS!! The following is expected storm surge…
Cape Sable to Captiva…10 to 15 ft
Captiva to Ana Maria Island…6 to 10 ft
Card Sound Bridge through Cape Sable, including the Florida Keys…
5 to 10 ft
Ana Maria Island to Clearwater Beach, including Tampa Bay…
5 to 8 ft
North Miami Beach to Card Sound Bridge, including Biscayne Bay…
3 to 5 ft
South Santee River to Fernandina Beach…4 to 6 ft
Clearwater Beach to Ochlockonee River…4 to 6 ft
Fernandina Beach to Jupiter Inlet…2 to 4 ft
North of North Miami Beach to Jupiter Inlet…1 to 2 ft
Rainfall amounts could reach 20 inches, especially where Irma makes landfall, general rainfall totals of 5 to 15 inches will be possible, with isolated areas of 25 inches possible.  Flash flooding will be possible.
Tornadoes will also be possible today, with an enhanced risk of severe storms for portions of the eastern Florida peninsula.
Now for the forecast track, once the core of Irma moves through the Keys, Irma is expected to move parallel to the west coast of Florida, this will make the exact landfall area difficult to pinpoint.  Once Irma do make landfall, it will continue to move north and northwest into east-central Alabama by early Tuesday morning as a tropical storm, then continue to weaken to a post-tropical system into the Tennessee and Ohio Valleys.  If you are in Florida today, remain indoors today, for the west coast of Florida, conditions will only worsen today!  Be safe and we will have another blog update between 11:30 and noon.
