| Brief Description: EVENT NARRATIVE: At 918 PM Saturday September 13th a tornado occurred in parts of Plymouth and Livonia in Wayne County. The Tornado path length was 2.6 miles and began just west of Starkweather Street near the railroad tracks in Plymouth and tracked eastward across the intersection of Interstates 96 and 275 and ended in Livonia at the intersection of Newburgh and Richfield Roads near Ladywood High School. The maximum path width of the tornado was roughly 200 yards in Plymouth and was 100 yards or less in most other locations along its path. Most of the damage along the path was to trees and was rated mostly at the EF0 level (less than 86 MPH). However, a short stretch of significant roof damage occurred in Plymouth to two apartment buildings in Lake Pointe Village and Brougham Manor. This damage was rated at the EF2 level, or roughly winds to 120 mph. EPISODE NARRATIVE: A warm front combined with tropical moisture to spawn a tornado in Plymouth. | |||||||||||

| Brief Description: EVENT NARRATIVE: This is the same tornado that began in Livingston County's Cohoctah Township. The tornado crossed into Genesee County approximately 3 miles west southwest of Fenton at 1649EST. The City of Fenton sustained the greatest amount of damage where the tornado path widened to approximately one-quarter mile, including the snapping and uprooting of hundreds of trees, de-roofing of both residential and municipal structures, and the partial collapse of a large retail structure near the intersection of Owen Road and U.S. 23. Of the approximately 250 homes/buildings damaged in Fenton, two were destroyed and five sustained major damage. The tornado was rated as EF2 in Fenton with wind speeds estimated at approximately 130 MPH. The average path width in Genesee County was 350 yards. One person in Fenton received minor injuries after being struck by flying glass. The tornado exited Genesee County one mile east of Fenton at 1700EST and then continued in Oakland County for another 5.5 miles. EPISODE NARRATIVE: Four tornadoes moved through portions of Southeast Michigan on August 24th, leading to an estimated $25M in total damages. One long-track tornado cut a path of EF0 to EF2 damage across Livingston, Geneseee, and Oakland Counties. Fenton was the hardest hit area, prompting the Governor of Michigan to declare a state of emergency there. Tornadoes also touched down in eastern Shiawassee County (rated as EF0), northwestern Washtenaw County (rated as EF0), and southwestern Lapeer County (rated as EF1). Thousands of trees were lost to the tornadoes. Although hundreds of homes and buildings were damaged, many destroyed, remarkably only one person was injured (minor cuts from flying glass) and there were no direct fatalities. One man died (indirect) of a heart attack during the cleanup process in Fenton. In addition to the tornadoes, there were widespread reports of severe thunderstorm wind gusts producing downed trees, limbs, and power lines. The hardest hit areas with respect to severe thunderstorm winds included areas around Flint, Lapeer, St. Clair, Chelsea, Monroe, and many locations in Livingston, Oakland, Macomb, Wayne and Lenawee Counties. | |||||||||||
