DISCUSSION AND OUTLOOK

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

At 1100 PM EDT (0300 UTC), the center of Tropical Depression Four

was located near latitude 21.4 North, longitude 79.7 West. The

depression is moving toward the west-northwest near 17 mph (28

km/h). A turn toward the northwest is forecast on Saturday,

followed by a slower motion toward the north and then the northeast

on Sunday and Monday. On the forecast track, the center of the

depression will move across Cuba overnight and on Saturday, and then

move generally northward over the eastern Gulf of Mexico Saturday

and Sunday, potentially reaching the Florida Gulf coast late Sunday

or Monday.

Maximum sustained winds are near 30 mph (45 km/h) with higher gusts.

Strengthening is forecast during the next several days, and the

depression is expected to become a tropical storm on Saturday and

continue strengthening over the eastern Gulf of Mexico through the

weekend.

The estimated minimum central pressure is 1010 mb (29.83 inches).

HAZARDS AFFECTING LAND

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

WINDS: Tropical storm conditions are expected in the warning area

late Saturday and Saturday night. Tropical storm conditions are

possible in the watch area in the Florida Keys and the southern

Florida peninsula by Saturday or Saturday night. Tropical storm

conditions are possible in the watch area along the Florida west

coast Saturday night and Sunday.

STORM SURGE: The combination of storm surge and tide will cause

normally dry areas near the coast to be flooded by rising waters

moving inland from the shoreline. The water could reach the

following heights above ground somewhere in the indicated areas if

the peak surge occurs at the time of high tide...

Bonita Beach, FL to Suwannee River, FL...2-4 ft

Tampa Bay...2-4 ft

Charlotte Harbor...2-4 ft

Card Sound Bridge, FL to Bonita Beach, FL...1-3 ft

Dry Tortugas...1-2 ft

RAINFALL: Tropical Depression Four is expected to produce rainfall

totals of 4 to 8 inches, with maximum rainfall totals up to 12

inches, across portions of Florida and along the Southeast U.S.

coast this weekend through Wednesday. This rainfall may result in

areas of locally considerable flash and urban flooding, with

isolated river flooding possible.

For Cuba, rainfall amounts of 1 to 2 inches, with localized higher

amounts, will be possible through Saturday. This may result in

isolated to scattered areas of flooding.

associated with Tropical Depression Four, please see the National

Weather Service Storm Total Rainfall Graphic, available at
