DUCK, N.C. (AP) — A year after being walloped by Hurricane Irene, residents rushed to put away boats, harvest crops and sandbag boardwalks Friday as the Eastern Seaboard braced for a rare megastorm that experts said would cause much greater havoc.

Hurricane Sandy, moving north from the Caribbean, was expected to make landfall Monday night near the Delaware coast, then hit two winter weather systems as it moves inland, creating a hybrid monster storm that could bring nearly a foot of rain, high winds and up to 2 feet of snow. Experts said the storm would be wider and stronger than last year’s Irene, which caused more than $15 billion in damage, and could rival the worst East Coast storm on record.

Officials did not mince words, telling people to be prepared for several days without electricity. Jersey Shore beach towns began issuing voluntary evacuations and protecting boardwalks. Atlantic Beach casinos made contingency plans to close.
