Nate weakens after second landfall on U.S. Gulf Coast

Staff Writers

Monday, October 9, 2017, 8:14 AM - Now downgraded to a tropical depression, then-category 1 Hurricane Nate made landfall near the mouth of the Mississippi River on Saturday, just days after slamming Central America and leaving some two dozen people dead.

Packing maximum sustained winds of 140 km/h, the storm came ashore once again near Biloxi, Miss., around 12:30 a.m. CDT Sunday, causing major flooding overnight for parts of the Gulf Coast, including in Biloxi and Mobile, Ala.

The storm rapidly weakened as it plowed through the Deep South; by 10 a.m. CDT, the National Hurricane Center had stopped issuing tropical statements on the system.

That said, the storm will still generate heavy rainfall as it tracks through the Tennessee Valley and central Appalachians through Monday. Flash flood and high wind watches are in place along its path, from southern Alabama stretching along the Appalachians into Virginia.

Nate has the potential to produce 75 to 150 mm  of rainfall, with isolated amounts of up to 250 mm possible for east of the Mississippi River from the central Gulf Coast into the Deep South, eastern Tennessee Valley, and southern Appalachians. The Ohio Valley into the central Appalachians could see upwards of 150 mm.

The hurricane is the third to hit the continental U.S. in six weeks. 

A state of emergency has been declared for all of Louisiana. CNN reports 1,300 National Guard troops have been mobilized ahead of the storm, with a mandatory evacuation in effect for Venetian Isles, Lake Catherine and Irish Bayou.

State of emergency declarations were made for Louisiana, Mississippi, and Alabama, as well as for parts of Florida ahead of the storm. More than 140,000 customers were reported to be without power along the Gulf Coast in the wake of the storm's landfall.

The storm has already claimed the lives of at least 25 people across Central America as floodwaters and mudslides caused widespread destruction.
