Algonquin Hits 'Major Flood' Stage; Multiple Rounds of Storms Coming

Algonquin Hits ‘Major Flood’ Stage; Multiple Rounds of Storms Coming

The Algonquin Tailwater has hit major flood stage, and there’s a possibility it could get worse, as multiple rounds of thunderstorms are possible later this week.

The National Weather Service Chicago on Tuesday reports that thunderstorms are possible over northern Illinois during mid and late week, with the return of a more
humid air mass providing potential for storms to produce heavy rainfall.

“While there is a high uncertainty in placement of storms within the region, there is some signal that along and north of Interstate 88 in northern Illinois and into Wisconsin may be the most favored,” the weather service says. “Given wet antecedent conditions over the Des Plaines, Fox River, and north branch of the Chicago River basins, this portion of far northeast Illinois is more susceptible to flooding than normal if multiple rounds of heavy rainfall were to pan out.”

Don Bryant, director of the Kane County Office of Emergency Management, said Tuesday that the Fox River remains closed to recreational watercraft.

Sandbag Supplies remain available to the public at the Kane County Transportation garage, 41W011 Burlington Road, St.Charles and at various municipal locations.
