ATLANTA (AP) -- A flood watch was posted for the northern half of Georgia through Tuesday night as the remnants of Fay soaked the state with driving rain.

The National Weather Service office at Peachtree City said no major flooding had been reported. The heavy rain caused pooling on roads, reduced visibility and slowed morning rush hour into downtown Atlanta.

Weather Service meteorologist Matt Sena said 3.67 inches of rain fell in Rome in northwest Georgia in the 24-hour period that ended at 8 a.m. Tuesday, with 2.63 inches in Columbus. He said unofficial reports show that 6 to 8 inches fell in the northeast Georgia mountains around Habersham County.

The southwestern corner of Georgia remained under a tornado watch, but no tornadoes had been reported. The Weather Service also issued a tornado warning early Tuesday for Cobb, DeKalb and Fulton counties, but it expired just before 9 a.m.

Tropical Depression Fay was centered near Tuscaloosa, Alabama, just before daybreak. It is expected to continue moving northeastward into Tennessee.
