Hurricane Sandy, Oct. 29, 2012

Richard Thomas walked through the flood waters in front of his home after assisting neighbors as Hurricane Sandy beared down on the East Coast today in Fenwick Island, Del. Forecasters warned that the New York City region could face the worst of Hurricane Sandy as it bore down on the U.S. East Coast's largest cities Monday, forcing the shutdown of financial markets and mass transit, sending coastal residents fleeing and threatening high winds, rain and a wall of water up to 11 feet tall. It could endanger up to 50 million people for days.
