Damaging Winds Oneida County

The National Weather Service surveyed localized areas of wind damage that occurred with severe thunderstorms in Oneida County on Monday May 24, 2004. Scattered tree damage was found along a path from the eastern shore of Oneida Lake to the town of Remsen. The greatest amount of damage was found in the village of Westernville, and in a rural area about 5 miles northwest of Rome. In those two locations, it was determined that downburst winds, possibly reaching speeds of 100 mph, caused extensive damage to dozens of large trees.

In both cases, the damage swaths were approximately 30 yards wide and 80 yards long. The trees were snapped and knocked down in a straight-line to slightly divergent pattern in both locations, indicating that the damage was most likely done by downbursts of strong winds, but not by a tornado.

Several reports of funnel clouds were received in the area between 4:30 and 4:50 PM EDT. It is likely that the storms that produced these funnel clouds also produced the damaging straight line winds.

The two panel animation shows 0.5 Base Reflectivity on the left, and 0.5 Storm Relative Motion on the right. Both are from the National Weather Service radar in Binghamton, NY. The loop is from 04:22 PM to 05:31 PM EDT ( or 2022 to 2131 UTC) May 24, 2004. The loop shows a line of storms moving across the eastern part of the county producing wind damage.
