| episode_narrative | A warm and muggy airmass persisted over southeast Michigan. A complex of thunderstorms moved east across northern Michigan in the early morning hours. Outflow from this thunderstorm complex moved south into southeast Michigan as a miniature cold front, and thunderstorms redeveloped along the leading edge of this outflow in the afternoon. Meanwhile, thunderstorms also developed in northeast Indiana, along the edge of a deck of low clouds. These separate areas of thunderstorms would merge over Metro Detroit in the late afternoon and early evening, producing tremendous amounts of rain. Many places had seen heavy rain the day before, and thus the area was quite vulnerable to flooding.At Detroit Metro Airport, 3.71 inches of rain fell on the 11th. This was the wettest September day ever in Detroit, and the 5th wettest day of all time. This was on top of the 1.65 inches that fell the day before. National Weather Service radar estimated around 5 inches of rain fell on the 11th in a swath from Brownstown Township to Allen Park in Wayne County. In Washtenaw County, 2.26 inches of rain fell in Ann Arbor, after 1.32 inches the previous day.The storms had a broad impact. Over 30,000 households were affected by power outages. About one hundred flights out of Detroit Metro Airport were cancelled, and numerous people were stranded at the airport overnight due to the multitude of flooded roads in the area. A collision on Interstate 94 in Harrison Township (Macomb County) during a downpour closed the highway for two hours. Sewage overflows were common in Wayne County, as the water treatment system was quickly overwhelmed; the failure of some pumping operations due to power outages contributed to the sewer backup. Several lawsuits were filed in connection with damage caused by raw sewage. |
