EF1 tornado in Otsego County, New York

A tornado touched down in woods near Route 51 between Mount Upton and Gilbertsville, producing EF0 damage until reaching Copes Corners Road where it strengthened to EF1, snapping and uprooting trees through a heavily wooded area. It moved up the hill and across the athletic fields of the Gilbertsville-Mount Upton Central School. Here, it threw metal bleachers several hundred yards to the north. It also tore a press box off steel beams, hurled a railroad tie used in a parking lot over a hundred feet into a fence, broke off metal poles used for hanging netting, and bent a soccer goal back in the southward direction. The field was littered with small tree missiles pointing in both directions with a southward direction on the left side of the path. A portable toilet was lifted and dropped about a half mile away and some other light material was found almost a mile away. The tornado continued to the northeast passing south of Gilbertsville, with damage primarily to trees. The path continued to narrow and weaken, ending a couple miles east of Gilbertsville.

A slow moving warm front pushed northward across central New York late in the afternoon on April 25th. A warm and relatively moist air mass covered the region, with showers and storms developing, especially in the unstable air south of the frontal boundary, where breaks in the cloud cover allowed temperatures to rise to near 70 degrees. Severe weather developed, and in addition to reports of severe wind damage and hail, plenty of wind shear in the vicinity of the warm front allowed for a few super-cell thunderstorms and tornadoes to develop. In addition, areas of heavy rain caused significant flash flooding in several locations of central New York.
