Winter 'Bomb Cyclone' Pounds East Coast

A massive winter storm described as a violent "bomb cyclone" continued to move up the East Coast on Thursday, shutting schools, canceling flights, knocking out power and sparking fears of coastal flooding.

Winter weather watches and warnings remained in place along a 1,000-mile stretch from North Carolina to northern Maine. LaGuardia Airport in New York announced that more than 90% of its flights Thursday will be canceled due to the storm.

Overall, some 2,800 flights were cancelled as of early Thursday, CNN reported. Some 77,000 customers were without power in several states, CBS News said.
