Hurricane Sandy Kills At Least 31 in Caribbean

Headed slowly for the U.S. while merging with a nor'easter

Slow-moving Hurricane Sandy, a late season Atlantic storm unlike anything seen in more than two decades, slogged toward the U.S. East Coast on Friday after killing at least 31 people on a trail of destruction across the Caribbean.

Forecasters said the storm, with an expanding wind field already 550 miles wide, had begun merging with a polar air mass over the eastern United States, potentially spawning a "hybrid" super storm that could wreak havoc along the U.S. East Coast.
