A strong storm system was moving toward Alabama, bringing the potential for severe weather during the overnight hours, forecasters said. WBRC Fox 6 Chief Meteorologist JP Dice said the main threats are from damaging winds and tornadoes. The likely timeframe for central Alabama was 12 midnight until 5 a.m. Some school systems said they will open late Tuesday, as a precaution. The Jefferson County schools, Leeds city schools, Birmingham city schools, and St. Clair County schools, all announced a 2-hour delay.
