Alberto downgraded to depression; flood threat, rains persist

MIAMI — Forecasters have downgraded Alberto to a subtropical depression but say a flood threat persists as the huge system continues to dump heavy rains.

The National Hurricane Center in Miami says Alberto, formerly a subtropical storm, weakened Monday evening just hours after making landfall in the Florida Panhandle. As of the 10 p.m. CDT advisory, Alberto was located about 50 miles (80 kilometers) west-northwest of Dothan, Alabama. Its top sustained winds are now down to about 35 mph (55 kph).

Forecasters say the center of the depression is moving to the north near 12 mph (19 kph). The storm is expected to pick up speed in coming hours and move over Alabama later in the night and early Tuesday as it spreads storms around the South.

Forecasters say rains from the farflung system could produce flash flooding in the hours ahead.
