EF1 tornado in Perry County, Pennsylvania

A NWS survey team confirmed a tornado which began in eastern Perry County, and crossed the Susquehanna River into western Dauphin County. The tornado touched down north of Route 850 in Perry County, between VFW Drive and Mountaindale Drive. The tornado tracked to the northeast, lifting occasionally as it moved across eastern Perry County and eventually to the Susquehanna River. The path indicated the tornado lifted and touched down several times. Damage was limited mainly to over 100 trees, which were snapped and uprooted. Photographic evidence helped in making the tornado declaration.

After crossing the Susquehanna River, the tornado touched down again in Dauphin Borough. Examination of the damage here indicated the tornado touched down again about one quarter mile east of Dauphin Borough on River Road. The tornado continued east about 1.5 miles...generally following Hillside Road...and dissipating as it began to climb Second Mountain. Six homes suffered moderate to major damage, and 150 trees were downed. Storm damage was consistent with maximum winds of around 90 mph. There were no injuries or fatalities.

In addition to the tornadic damage, downburst/straight line wind damage was noted at least 1.5 miles to the west of Dauphin Borough along the river, and in eastern Perry County, also near the Susquehanna River.
