…THE FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 745 AM CDT FOR
NORTH CENTRAL COOK COUNTY…
At 556 AM CDT, Doppler radar continued to indicate showers and
isolated thunderstorms across the warned area. The heaviest rainfall
has ended, but runoff and flash flooding will continue from the very
heavy rain that fell overnight. Doppler radar and rainfall
measurements suggest many areas picked up between 2 to locally over
3.5 inches of rain in just a couple hours overnight.
Law enforcement officials report flooding on many roads and some
roads are closed and impassable. Do not drive around barricades and
don`t drive into areas where water covers the roads.
Some locations that will experience flooding include…
Arlington Heights, Des Plaines, Mount Prospect, Glenview, Buffalo
Grove, Wheeling, Park Ridge, Northbrook, Wilmette, Morton Grove,
Winnetka, Glencoe, Rosemont, Niles, Prospect Heights, Northfield and
Golf.
PRECAUTIONARY/PREPAREDNESS ACTIONS…
Be especially cautious at night when it is harder to recognize the
dangers of flooding.
