Key Messages:
 
1. Heavy rainfall associated with post-tropical cyclone Isaias will 
continue across the Southern Appalachians and Southeast today. 
Considerable flash and urban flooding will be possible. Landslides 
are also possible across the Southern Appalachians.
 
2. Strong wind gusts continue to pose a threat across the 
southeastern United States today, including Georgia, the southern 
Appalachians, and extending west through much of central and 
northern Alabama, Mississippi, and Tennessee. Scattered power 
outages and downed trees and powerlines may occur, with the risk 
highest in elevated terrain.

3. Swells from Isaias will continue to affect much of the Gulf 
coasts of the United States, Mexico, and western Cuba this weekend. 
These swells are likely to cause life-threatening surf and rip 
current conditions. Please consult products from your local weather 
office.

4. A couple of tornadoes are possible today across eastern Georgia 
and the Carolinas.
