DISCUSSION AND OUTLOOK ---------------------- At 400 AM CDT (0900 UTC), the center of Tropical Depression Sally was located near latitude 31.8 North, longitude 85.7 West. The depression is moving toward the northeast near 12 mph (19 km/h), and a northeastward to east-northeastward motion is expected into Friday. On the forecast track, the center of Sally will move across southeastern Alabama this morning, over central Georgia this afternoon and evening, and move over South Carolina late tonight into Friday. Maximum sustained winds have decreased to near 30 mph (45 km/h) with higher gusts. Additional weakening is forecast during the next couple of days, and Sally is expected to become a remnant low by tonight or Friday morning. The estimated minimum central pressure based on nearby surface observations is 1000 mb (29.53 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Sally can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT4 and WMO header WTNT44 KNHC, and on the web at www.hurricanes.gov/text/MIATCDAT4.shtml RAINFALL: Rainfall totals expected as Sally moves across the Southeast U.S. through Friday: Central Georgia: Sally will produce additional rainfall totals of 3 to 6 inches, with localized higher amounts, on top of 3 to 6 inches which has already fallen. Widespread flash flooding and minor to moderate river flooding is likely. Central to upstate South Carolina: 3 to 6 inches, with isolated amounts of 10 inches. Widespread flash flooding and minor to moderate river flooding is likely. Western to central North Carolina into south-central and southeast Virginia: 4 to 6 inches, isolated amounts up to 8 inches.

The threat of tornadoes will shift northeastward into eastern Georgia and much of the Carolinas today and tonight.

These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
