SHIP BOTTOM, N.J. —
Mandatory evacuations were under way in southern New Jersey's barrier islands, which people were ordered to leave by Sunday afternoon, and Christie ordered the evacuations of all Atlantic City casinos and said state parks would close.
"We should not underestimate the impact of this storm and not assume the predictions will be wrong," Christie said during a storm briefing Saturday in North Midletown, near the coast. "We have to be prepared for the worst."
In North Carolina's Outer Banks, light rain was falling Saturday and winds were building up to a predicted 30 to 50 mph. Gov. Beverly Purdue declared a state of emergency for some coastal areas, and a steady stream of campers and other vehicles hauling boats left the low-lying islands for the mainland. Residents feared a temporary bridge built after Irene last year poked a new inlet through the island could be washed out again, severing the only road off Hatteras Island.
In Ship Bottom, N.J., Russ Linke was taking no chances Saturday. He and his wife secured the patio furniture, packed the bicycles into the pickup truck and headed off the island.
"I've been here since 1997, and I never even put my barbecue grill away during a storm, but I am taking this one seriously," he said. "They say it might hit here; that's about as serious as it can get."
After Irene left millions without power, utilities were taking no chances and were lining up extra crews and tree-trimmers. Wind threatened to topple power lines, and trees that still have leaves could be weighed down by snow and fall over if the weight becomes too much.
New York City began precautions for an ominous but still uncertain forecast. No decision had been made on whether any of the city's public transportation outlets would be shut, despite predictions that a sudden shift of the storm's path could cause a storm surge of 3 to 6 feet and send water into the subway system.
