After strengthening into a hurricane shortly after noon Tuesday, Isaac has been lashing the Gulf Coast with unrelenting thunderstorms, damaging winds and storm surge flooding.

Isaac was downgraded to a tropical storm at 2:00 p.m. CDT Wednesday. However, the large circulation around the storm will continue to cause storm surge, flooding rainfall and damaging winds through at least early Thursday morning.
Hurricane Isaac officially made landfall in far southeastern Louisiana in Plaquemines Parish with maximum sustained winds of 80 mph at 6:45 p.m. CDT Tuesday. Isaac then moved out into West Bay becoming stationary for much of Tuesday night. Isaac has made a second landfall near Port Fourchon with winds of 80 mph around 4:00 a.m. CDT Wednesday.
Currently, blinding, wind-driven rains are lashing southern and central Mississippi, southwestern Alabama and southern and eastern Louisiana. More than a foot of rain has fallen in a few communities, including 17.0 inches at Audubon Park in New Orleans, La.
Storm surge flooding has been occurring along the Alabama, Mississippi and Louisiana coastlines since Tuesday afternoon with roads closed in multiple areas, including Mobile, Ala., and New Orleans.

Tornadoes have been reported in Gulfport and McHenry, Miss., and more tornadoes will be possible across southern and eastern Louisiana, Mississippi and southeastern Arkansas into Thursday. The main threat for tornadoes will lie the north and east of Isaac's center.

Rising storm waters prevented firefighters from responding to this fire in Bay St. Louis, Miss. so they used an airboat to make sure it didn't reach neighboring homes.
