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: Sally has produced storm totals of 10 to 20 inches, with isolated amounts of 3035 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. Please consult products from your local weather office.

At 700 PM CDT (0000 UTC), the center of Tropical Storm Sally was located near latitude 31.5 North, longitude 86.5 West. Sally is moving toward the northeast near 7 mph (11 km/h), and a northeastward motion at a slightly faster forward speed is expected tonight through Thursday night. On the forecast track, the center of Sally will move across southeastern Alabama tonight, over central Georgia on Thursday, and move over South Carolina Thursday night.

Maximum sustained winds have decreased to near 45 mph (75 km/h) with higher gusts. Additional weakening is expected as the center moves farther inland tonight, and Sally is forecast to become a tropical depression tonight.

Tropicalstormforce winds extend outward up to 125 miles (205 km) from the center.

The estimated minimum central pressure is 994 mb (29.35 inches).

The center of Sally continued its slow trek inland across thefar western Florida Panhandle early this afternoon, and it isnow located over southeastern Alabama. The satellite and radar presentation of the storm has continued to degrade, and surface observations and Doppler radar data show that winds have continued to gradually decrease. The initial intensity has been reduced to 50 kt, and rapidly weakening should continue as the circulation moves farther inland. Sally is forecast to become a tropical depression tonight or early Thursday, and degenerate into a remnant low in 36-48 hours. The system is expected to be absorbed by a frontal boundary near the southeast U.S. coast on Friday.

Sally is moving north-northeastward at a slightly faster forwardspeed of 6 kt. The cyclone should turn northeastward and move at aslightly faster forward speed as it become embedded within thesouthern extent of the mid-latitude westerlies, and this generalmotion should continue until dissipation occurs. The dynamicalmodels are tightly clustered and the NHC track is near the centerof envelope.

Although the winds and storm surge from Sally are expected tocontinue to subside this evening, heavy rainfall and flooding willcontinue to spread inland over southeastern Alabama, centralGeorgia, and western South Carolina over the next day or so.
