NWS Weather Prediction Center College Park MD   AL092026

Key Messages:
 
1. Areas of heavy rainfall will continue across portions of the 
Central Appalachians and Mid-Atlantic today, with localized flash 
and urban flooding possible. River flooding continues in western 
North Carolina. 

2. Swells from Isaias will continue to affect much of the Gulf and
Southeastern Atlantic coasts of the United States today. These 
swells are likely to cause life-threatening surf and rip current 
conditions. Please consult products from your local weather office.
 
3. A couple of tornadoes are possible today across the Piedmont and
Coastal Plain of Virginia and North Carolina.
