About 10 million people in Texas, Louisiana, Alabama, Mississippi, Georgia and the Florida Panhandle were under flash flood watches Friday.
The remnants of Tropical Storm Arthur continue to bring heavy rain and life-threatening flash flooding to the Southeast, including Louisiana and Mississippi.
Earlier this week, Louisiana residents reported downed trees, heavy rain and strong winds. NBC News’ on-the-ground reporting team witnessed knee-deep water, overturned trains and destroyed buildings.
Arthur is expected to appear in the Atlantic Ocean on Friday afternoon, with a 10% chance of regaining strength over the next few days. Even if it does, no further impacts are expected and it will likely move away from the coast.
On Friday, a slow-moving storm could produce 2 to 3 inches of rainfall per hour, potentially causing additional flash flooding. Cities at moderate risk of flooding include Hattiesburg and Biloxi in Mississippi and Mobile and Dothan in Alabama, where additional rainfall totals through Saturday could reach 4 to 6 inches.
The state record for 24-hour precipitation in Louisiana is 22 inches. Preliminary precipitation totals expected so far include 29 inches in Cottonport, 22 inches in Plaucheville and 17 inches in Simsport near the Atchafalaya River.
If preliminary readings are verified, Friday’s rainfall will set a new 24-hour record for the state.
Precipitation totals for other parts of the South include 1 foot of rain in Perkinston and Black Creek, Mississippi, and 11 inches of rain in Village Mills, Texas.
