The National Weather Service says at least four tornadoes touched down in Alabama during this week's storms, including an EF-2 tornado that flung a semitrailer onto the roof of an industrial plant in the Fort Payne area. The Fort Payne-area twister was brief but powerful, with estimated winds up to 125 mph. Survey crews from the weather service say it flipped three large semitrailers, vaulting one into the air and onto the factory's roof around 12:30 a.m. Friday. Another EF-1 tornado touched down at a marina on the Tennessee River in Limestone County, then damaged some nearby condos and homes Thursday night. Two other Thursday night twisters snapped and uprooted trees and damaged some homes in the Cartwright community in northern Alabama and in the Anderson area of Lauderdale County.
