Chicago flood of August 1987

Dear Tom,
Please refresh our memories of the August 1987 flood.
Thanks, Larry
Dear Larry,
August 1987 had opened hot and dry in Chicago, and vegetation was stressed
from the lack of rain. With a front setting up west of the city on Aug. 13,
forecasters were hopeful for some much-needed rain. Well, the rains came,
but unfortunately they didn't stop. Torrential downpours descended upon the
Chicago region as repeat waves of thunderstorms "trained" over areas from
Rockford to Chicago's North Side. When the rains finally ended more than 17
hours later, 9.35 inches of rain had inundated the O'Hare area, making it an
inaccessible island for nearly 24 hours. Three people died and flood damage
exceeded $220 million. The wet weather continued, and by the end of the
month O'Hare had logged 17.10 inches of rain, making August 1987 the city's
wettest month on record.
