Forecasters warn of 'dangerous travel and infrastructure impacts' for days

A massive winter storm dumped sleet, freezing rain and snow across much of the U.S. on Sunday, bringing subzero temperatures and halting air and road traffic. Tree branches and power lines snapped under the weight of ice, and hundreds of thousands of homes and businesses in the Southeast were left without electricity.
The ice and snowfall were expected to continue into Monday followed by very low temperatures which could cause “dangerous travel and infrastructure impacts” for days, the National Weather Service said.
