A tornado watch remained in effect for much of the rest of northwestern Georgia, and a severe thunderstorm warning was in effect for several counties north and east of Cobb untiil 5:30 p.m. There were scattered reports of hail just before 5 p.m., including in southern Cherokee County.
The twister watch applies to 33 counties in the north and west portions of Georgia, including metro Atlanta. It applies to areas north of a line from LaGrange to Athens, and is in effect until 8 p.m.
A "watch" means conditions are conducive for the threatening weather; a "warning" means the weather may be imminent.
Storms capable of producing isolated tornadoes, damaging winds of 70 mph and hail were expected to move through the area between 4 p.m. and 7 p.m., Channel 2 Action News meteorologist David Chandley told the AJC Monday afternoon. He said as much as a half inch of rain could fall.
The National Weather Service placed areas south of that line under a slight risk for severe storms.
Tuesday's forecast is for a clear, sunny day with a high in the low 60s -- down from Monday's temperatures in the 70s.
The tornado watch comes one day before the official start of tornado season. The Georgia Emergency Management Agency noted the close timing in a statement Monday, advising people to read up on tornado preparedness at the agency's website. Their advice includes sheltering in an interior room away from windows, listening to NOAA Weather Radio and monitoring other media and watching for downed power lines in the aftermath of a storm.
