Tropical Depression Sally Discussion Number  24
NWS National Hurricane Center Miami FL       AL192020
1000 PM CDT Wed Sep 16 2020

Although it remains a prodigious rain producer, surface 
observations indicate that Sally has weakened to a 30-kt depression 
over southeastern Alabama.  The cyclone will continue to gradually 
spin down over the southeastern United States, and is likely to 
become a remnant low pressure system before merging with 
a frontal zone near North Carolina on Friday.

The cyclone is moving northeastward near 8 kt. A northeastward to 
east-northeastward motion is expected over the next 36 hours or so 
as the system moves to the south of a broad trough over the 
northeastern United States.  The official track forecast is about 
in the middle of the model guidance.


KEY MESSAGES:
 
1. Significant and widespread flooding is expected across inland 
portions of Alabama, central Georgia and upstate South Carolina, and 
widespread flooding is possible across western/central North 
Carolina, and far southeast Virginia.  Most widespread moderate to 
major river flooding will crest by the weekend, but rivers will 
remain elevated across southern Alabama and the Florida Panhandle.
