The National Weather Service says investigators will examine storm damage in upstate New York to determine if it was caused by a tornado or straight-line winds.
The weather service reports that trees and power lines were knocked down, several homes were damaged and a barn collapsed as strong storms moved through rural Schenectady and Albany counties between 3:30 and 4:30 Thursday afternoon. A tornado warning was in effect at the time, based on radar images.
Meteorologist John Quinlan at the National Weather Service in Albany said investigators will survey damage in the Schenectady County town of Delanson on Friday to determine if it was caused by a tornado.
The storm system weakened as it moved eastward across the Hudson Valley.
