|Brief Description: Thunderstorms spawned a strong F3 tornado in southern Lebanon County during the afternoon of July 14. The tornado first touched down in far western Lebanon County at 3:05 pm EDT, about 1 mile west of the town of Campbelltown. The tornado traveled east, and struck a housing development about one quarter mile south of Route 322. A total of 32 homes were destroyed, with another 37 homes sustaining significant damage. An additional 50 homes and 9 farm buildings in the area were damaged by downburst winds associated with the thunderstorm which spawned the tornado. The tornado continued along a path to the east for seven and one half miles. The tornado crossed Route 322 west of Mount Pleasant, and continued east, mainly across fields, until it lifted up about 2 miles northwest of the town of Cornwall at 3:15 pm EDT. The width of the tornado was one quarter mile. Although the tornadic damage was confined to the path described, additional damage occurred outside this path, again associated with downburst winds from the parent thunderstorm. Winds were estimated between 175 and 200 MPH, making this a strong F3 tornado on the Fujita scale. The tornado injured 24 persons, one critically. There were no deaths. The American Red Cross opened a mass care center, where over 50 people required assistance with sheltering. Between 25,000 and 30,000 customers lost power in Lebanon and Berks Counties as a result of the storms.|
