Tropical Depression Sally Discussion Number 24

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.
