ATLANTIC CITY, N.J. (AP) — Forecasters say Hurricane Sandy is continuing to move quickly and should make landfall by early Monday evening in southern New Jersey or Delaware.

The National Hurricane Center said the storm's top sustained winds are holding at about 90 mph (150 kph) with higher gusts. At 4 p.m. EDT, Sandy's center was about 55 miles (150 kms) east-southeast of Cape May, N.J. It was headed west-northwest at 28 miles per hour (44 kph).

Forecasters say Sandy should reach the coast within three to five hours.

Sandy was set to collide with a wintry storm from the west and cold air streaming down from the Arctic. The combination superstorm could menace some 50 million people in the most heavily populated corridor in the nation, from the East Coast to the Great Lakes.
