Alabama ? Severe weather howled through much of the nation Sunday, producing damaging tornadoes in the South that injured nearly 30 people and treating winter-weary parts of the Midwest to freezing rain, snow and flooding.

A tornado damaged or destroyed about 200 homes and businesses in Prattville, outside Montgomery, where Mayor Jim Byard said crews searched for people trapped in the wreckage.

No fatalities were immediately reported, but two people were critically injured, said Fire Department official Dallis Johnson. Twenty-seven people had minor injuries, officials said.

A tornado destroyed four homes in Escambia County, Fla. About 60 other homes, businesses and storage buildings were damaged to varying degrees, said county spokeswoman Sonya Daniel.

Freezing rain and snow fell across the southern two-thirds of Wisconsin, still weary from a major snowstorm that stranded hundreds of motorists and snarled travel for days.

Heavy snow and slush closed Kansas City International Airport for almost six hours, the longest closure in its 35-year history, authorities said. Dozens of flights were canceled.
