An extreme deluge nearly unprecedented in Detroit history brought the
Motor City to a virtual standstill during the evening rush hour on
Monday, with 4.57" of rain falling at the official measurement site at
Detroit Metro Airport. The only wetter day in Detroit history (4.75")
occurred on July 31 - August 1, 1925--over two years before the Ford
Model A went into production. A slow-moving low pressure system tracked
over Michigan on Monday, bringing thunderstorms that dumped 4 - 6" of rain--nearly
two months' worth--over Metro Detroit in just four hours. Many major
expressways in the city remain closed today due to floodwaters and flood
damage. The northern Detroit suburb of Warren, where 5" of rain fell,
has declared a state of emergency. Over 1,000 vehicles have been abandoned on major thoroughfares,
and many more in neighborhoods. One person died in the storm--a heart
attack victim found dead in her flooded car. All of Detroit's major
expressways were closed due to flooding during the deluge; in my 40
years living in the area, I've never seen a flood do that. Detroit radar
shows that a new round of showers is affecting the area this afternoon,
which will slow efforts to drain the water off of blocked roads.
