(AP) – Roads crusted with icy slush left over from as much as a foot of snow made travel dangerous across north Alabama early Thursday, but rising temperatures began melting away some of the problems.
The Alabama Department of Transportation plowed snow off major roads, and the sun peeked through at times to help. Still, dozens of drivers spent hours in vehicles stuck overnight on a slippery Interstate 65 north of Birmingham because of wrecks.
Power outages affected about 12,000 homes and businesses at daybreak, according to Alabama Power Co., but crews worked to restore electrical service.
Conditions were bad enough in the Tennessee Valley that the Huntsville City Council canceled a meeting set for Thursday night. Municipal court and trash pickup also was delayed.
High temperatures were expected to reach the upper 30s and low 40s. Forecasters said the weather should be warm enough to clear many roads, but lingering water could refreeze earlyFriday, with temperatures again predicted to fall below freezing.
