Tornado in SENECA, NEW YORK
From 21-JUN-07 14:46:00 to 21-JUN-07 14:55:00 (EST-5)
Location: SHELDRAKE
Tornado F-scale: EF1
Property damage: 10.00K
Crop damage: 0.00K
Reported by: NWS Storm Survey

A National Weather Service storm survey team found a swath of wind damage in southeastern Seneca County, within the Sheldrake area of the town of Ovid. The pattern of damage was consistent with that of an EF-1 tornado on the Enhanced Fujita Scale. The degree of damage, which consisted mainly of snapped off and uprooted trees, indicated that maximum wind speeds were around 90 mph.
The tornado touched down in Sheldrake, near the northern end of Wyers Point Road, just east of State Route 89 and near the western shore of Cayuga Lake at about 3:46 pm EDT. The tornado then tracked southeast for about 1.5 miles, nearly parallel to both Wyers Point Road and the Cayuga Lake shoreline. The observed damage had a width of up to about 100 yards. Numerous trees sustained damage along this path length. Several very large trees were uprooted, and many more were snapped off. Utility poles in this same vicinity were either knocked down or sheared off. The orientation of the tree damage suggested a pattern of cyclonic rotation. Eyewitness accounts also detail both violently rotating debris just above ground level, and visual sighting of a funnel down to the surface near the shoreline. Any observed structural damage was relatively minor. A metal road sign was uprooted and blown across County Route 139, and a garage just off Wyers Point Road sustained roof damage from fallen trees. The tornado eventually crossed County Route 139 before emerging over the waters of Cayuga Lake between 3:50 and 3:55 pm EDT.
At that point, evidence suggests that the tornado lifted back toward the cloud base over the open waters of Cayuga Lake. One eyewitness account from the King's Ferry Fire Station, which was about 2 miles east of the storm at this time, sighted a funnel cloud over Cayuga Lake, with the funnel observed to be well above the surface of the water.
