The same storm that dropped record rainfall over South Texas will deliver the soaking rain to the Deep South today into Friday.
After spreading over New Orleans, the rain will reach Mobile and Tallahassee this afternoon. Montgomery, Albany, Atlanta, Augusta, Columbia, Charleston and Jacksonville will get soaked tonight into Friday.
The Deep South is highly susceptible to more flooding since this December has been extremely wet. New Orleans and Savannah have received 22.48 inches and 8.14 inches, respectively, of rain so far this month (through Wednesday).
Southeastern Louisiana to southeastern South Carolina will pick up 2 to 3 inches of rain through Friday. Residents should prepare for flash flooding to quickly ensue in urban and low-lying areas, as well as along small streams.
As the rain's runoff drains downstream, already swollen rivers will further rise and flood neighboring land, roads and communities through the weekend.
The rain threatens to cause flight delays. Motorists are urged to slow down on Interstates 10, 20, 65, 75 and 95 as the rain pours down. Fast-traveling vehicles could hydroplane as water ponds on these interstates and other highways.
The storm will also trigger potentially damaging thunderstorms across the Florida Peninsula on Friday. At the same time, snow and ice will begin to fall over the mountains and piedmont of the Carolinas.
