Storm hits Louisiana, Mississippi
Hurricane Nate made U.S. landfall Oct. 7 in southeast Louisiana then again Oct. 8 near Biloxi, Miss. The storm first hit the U.S. as a Category 1 hurricane with winds of 85 mph, but it downgraded to a tropical depression Oct. 8 as it moved inland. It was the first hurricane to make landfall in Mississippi since Hurricane Katrina in 2005.
Many coastal areas experienced a hurricane warning, and made storm preparations. Mississippi Gov. Phil Bryan declared states of emergency in six counties. By the end of the day Oct. 8, Nate was drenching the Deep South, Tennessee Valley and central Appalachian Mountains with heavy rains. The storm’s winds have left 100,000 customers in Mississippi and Alabama without power, but the storm's receding floodwaters reportedly did not leave signs of widespread damage in the city Katrina affected. No storm-related deaths or injuries were immediately reported.
