HAZARDS AFFECTING LAND
———————-
RAINFALL: 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. Historic and catastrophic flooding, including widespread moderate to major river flooding, will continue across this region. Additional rainfall of 1 to 4 inches is possible across the Florida Panhandle from Tallahassee to the Apalachicola River.

Rainfall totals expected as Sally tracks across the Southeast through Friday:

Southern Alabama and central Georgia: 4 to 8 inches with isolated amounts of 12 inches, resulting in significant flash flooding and widespread minor to moderate and isolated major river flooding.

Central to upstate South Carolina: 4 to 7 inches, with isolated amounts of 10 inches. Widespread flash flooding and minor to 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.

STORM SURGE: Water levels remain elevated along the Florida Panhandle coast but will continue to recede over the next several hours.

WIND: Tropical storm conditions will continue in portions of the warning area this evening.

TORNADOES: A few tornadoes may occur tonight across portions of northern Florida and southern Georgia. The threat of tornadoes will shift northeastward into parts of eastern Georgia and much of the Carolinas on Thursday.

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.
