moderate river flooding is possible.
Western to central North Carolina and far southeast Virginia: 4 to 6
inches, isolated amounts up to 8 inches. Scattered flash flooding
and widespread minor river flooding is possible.
Sally has produced storm totals of 10 to 20 inches, with isolated
amounts of 30-35 inches, across the central Gulf Coast from the
Florida Panhandle west of Tallahassee to Mobile Bay, Alabama. Most
moderate to major river flooding will crest by the weekend, but
rivers will remain elevated.
STORM SURGE: Water levels remain elevated along the Florida
Panhandle coast but will continue to recede over the next several

southern Georgia and northern Florida. The threat of tornadoes will
shift northeastward into eastern Georgia and much of the Carolinas
SURF: Swells from Sally will continue to affect the Gulf Coast
from the Florida Big Bend westward to southeastern Louisiana during
the next day or so. These swells are likely to cause life-
threatening surf and rip current conditions. Please consult
products from your local weather office.
