The National Weather Service has confirmed that a tornado destroyed the homes in upstate New York where four people were killed.
Barbara Watson, the meteorologist leading the agency's survey team says that the violent winds Tuesday were at least 100 mph and reached undetermined higher speeds to cause the damage they're seeing in the Madison County town of Smithfield, between Syracuse and Utica.
She says Wednesday that one two-story home is gone, the structure blown away and leaving only the foundation.
Authorities are scheduled to release more details later Wednesday.
Severe thunderstorms packing strong winds swept through a number of Eastern states on Tuesday, killing five people, destroying or damaging numerous houses and leaving nearly 200,000 without power Wednesday.
