DISCUSSION AND OUTLOOK

----------------------

At 200 PM EDT , the center of Tropical Storm Sally was

located near latitude 25.6 North, longitude 81.6 West. The

depression is moving toward the west near 7 mph (11 km/h), and a

turn toward the west-northwest is expected later today or tonight. A

west-northwestward or northwestward motion is then expected during

the next couple of days. On the forecast track, the center is

forecast to move over the southeastern and eastern Gulf of Mexico

later today and Sunday, and then move over the north-central Gulf of

Mexico Sunday night and Monday.

Maximum sustained winds have increased near 40 mph (65 km/h) with

higher gusts. Additional strengthening is expected over the next

couple of days, and Sally is forecast to become a hurricane by late

Monday.

Tropical-storm-force winds extend outward up to 80 miles (130 km)

south and southeast of the center, just to the south of the Florida

Keys.

The estimated minimum central pressure is 1004 mb (29.65 inches).

HAZARDS AFFECTING LAND

----------------------

WIND: Wind gusts to tropical-storm force are possible across the

southern portion of the Florida peninsula today, especially over

the Florida Keys. Tropical storm conditions are possible in the

watch area in the Florida Panhandle by Sunday night.

RAINFALL: Sally is expected to produce total rainfall of 3 to 6

inches with isolated 8 inch amounts over the Florida Keys through

tonight with 2 to 4 inches and isolated maximum amounts of 6 inches

across southern Florida and the western Florida coast to the Tampa

Bay metro area. This rainfall will produce flash and urban flooding

across southern Florida and prolong high flows and ongoing minor

flooding on rivers across Central Florida.

Sally is expected to produce through Tuesday rainfall of 3 to 6

inches with localized amounts of 8 inches along the Gulf Coast from

the Florida Peninsula to southeast Louisiana and 2 to 4 inches

farther inland over far southern Alabama, Mississippi and southeast

Louisiana. This is expected to be a slow-moving system that will

likely continue to produce heavy rainfall and considerable flooding

near the central Gulf Coast through the middle of next week. Flash,

urban and rapid onset flooding along small streams and minor to

isolated moderate flooding on rivers is likely.

SURF: Swells are expected to spread northward along the

west-central coast of Florida and the Florida Panhandle during the

next couple of days. These swells are likely to cause

life-threatening surf and rip current conditions. Please consult

products from your local weather office.

TORNADOES: A tornado or two is possible today and tonight over

southern Florida.
