A Circa 1940 pole barn was destroyed and numerous trees were snapped or uprooted just over a half a mile west of Chicora north of 108th Avenue. Further down the tornado's path, garage doors were blown out and carried 300 yards while two boats were blown out of the garage. The house suffered 80% shingle loss with one 2-foot diameter hole in the roof on the home's west side. This was approximately 0.35 miles north of Chicora. The most extensive damage occurred approximately one mile northeast of Chicora along 42nd Street. A roof was partially torn off of a house. A barn was blown about 20-feet off of its foundation. There were several telephone poles snapped with wires wrapped around a tree. A roof was ripped off a small unoccupied house with one wall collapsed. Debris was lofted up to one-half mile across a field. More shingle loss was found on the west side of a home located two-miles northeast of Chicora. Nearly 80% shingle loss was witnessed. Several utility poles were snapped with widespread tree damage through the area. More damage to a home was observed about a quarter-mile west of Schermerhorn Lake. The damage happened when numerous falling trees crushed it. One-quarter mile of 39th street was blocked by fallen trees. The trees were piled up to 15-feet deep on the road. As the tornado was weakening, a 30-foot metal tower was bent over half way up. This was located near the intersection of 37th Street and 109th Avenue.

Brief Description: EVENT NARRATIVE: A survey of the area between Baroda and Stevensville indicated damage consistent with a tornado. The damage started on Marrs Road, just west of Stevensville-Baroda Road. and continued east-northeast. The damage started with a travel trailer being thrown and destroyed as well as some tree damage. The circulation tracked mainly over open fields until reaching an area of homes on Lincoln Ave where the entire roof was ripped off a home (DI: FR12, DOD: 6) and another home suffered slightly less roof damage. The circulation continued northeast, crossing Hollywood Road, north of Linco Road. Several one year old 24 inch diameter power poles were snapped (DI: ETL; DOD 4). In addition, a harrow and trailer were thrown from a barn roughly 150 to 200 yards into a field. The circulation appears to dissipate north of Linco Road, on Scottdale Road. The tornado was roughly 200 yards wide at its peak. Maximum winds are estimated at around 125 mph. EPISODE NARRATIVE: A warm front worked north towards lower Michigan during the evening hours of the 5th. Storms were initially slow to organize, but quickly intensified and became super cellular as they moved off Lake Michigan. A combination of tornadoes and micro bursts were found in surveys across Berrien, Cass and St. Joseph counties. | |||||||||||
