Tornadoes in U.S. South Kill 48 in Rare Winter Strike (Update5)

By Demian McLean

Feb. 6 (Bloomberg) -- Tornadoes swept through the southern U.S. late yesterday, killing at least 48 people, sparking a pipeline explosion in Tennessee and ripping the roof off a building at FedEx Corp.'s main airport hub.

The ``extremely dangerous'' twisters, spawned by unseasonably warm temperatures, prompted the first high-risk weather alert issued in February in 10 years, AccuWeather.com said. Heavy rain, damaging winds and hail are possible from the Carolinas to southern New Jersey today, AccuWeather said.
