Fifty three million people across the United States were in harm’s way as a powerful storm raged across the Midwest on Sunday, spawning at least one deadly tornado that left a path of destruction in parts of Illinois, NBC News reported. Parts of the Great Lakes, Ohio Valley, lower-middle Mississippi Valley and Tennessee Valley are among the areas most at risk for widespread damaging winds and possible tornadoes, experts with the Weather Channel said. At least one person was confirmed killed in a storm-related incident, the Illinois Emergency Management Agency reported. National Weather Service said at least 10 tornadoes touched down in Illinois. At least 83,000 customers were without electrical power Sunday evening in central Illinois. Rescue teams are deploying to multiple areas across Illinois, focusing on the hard-hit Washington and Gifford areas, an emergency agency spokesman said. The Weather Channel predicts the storm will diminish as it moves east through Pennsylvania, Maryland and New Jersey, but high winds could reach as far as New York on Monday morning.
