The National Weather Service has confirmed that three tornadoes hit upstate New York during severe storms on Tuesday.

The worst devastation was in the town of Smithfield, a rural area between Utica and Syracuse where four people were killed.

National Weather Service meteorologist Barbara Watson says Thursday the storms that hit both Deerfield, south of Utica, and Lowville, about 55 miles north of Utica, also spawned tornados. No one was injured in either place.

The Deerfield tornado was rated EF-1, with wind speeds of 65 to 110 mph and was 60 yards wide. The Lowville tornado traveled 10 miles and also was an EF-1, with wind speeds of 95 to 100 mph and 300 yards at its widest.

Investigators are still working to determine the strength of the Smithfield twister.
