PHOTOS: Irma tracks through southeastern U.S.

Tuesday, September 12, 2017, 7:57 AM - After making two landfalls in Florida, former Hurricane Irma is now a post-tropical cyclone as it moves towards the Tennessee and Ohio Valleys.

At 9 a.m. Sunday, Irma was a Category 4 hurricane as it touched down in Cudjoe Key, Fla. At 3:35 pm, the storm made its second landfall on the west-coast Marco Island as a Category 3 hurricane.

The storm left Florida Monday by 5 p.m. It continues to weaken as it tracks across the southeastern U.S. However, it continues to bring moderate rainfall, with flash flood watches in effect for portions of the southern Appalachians.

Barbuda, part of the island nation of Antigua and Barbuda, took a direct hit from the storm early Wednesday, and although only one person was reported killed there, its Prime Minister told media the island is largely uninhabitable, with more than 90 per cent of structures destroyed.

Elsewhere in the region, authorities in St. Maarten say it could take months to recover from the damage left behind by the storm's impact on the region, and BBC reports troops will be deployed to deter looting.
