The last 7 weeks have been historically wet in Chicago

The Chicago area is making some soggy history.

The National Weather Service says more rain - 12.411 inches - has fallen in the city since May 1 than has ever fallen during the same period since records started being kept in 1871.

The weather service has warned of flooding in parts of the Fox, DuPage and Des Plaines rivers, with water levels remaining elevated in some areas for as long as a week.

The Fox River in Algonquin is expected to see the heaviest flooding. Officials predict the water there will rise as much as 2 feet, bringing it into "moderate" flood levels by Friday morning. Water levels along the Fox River near Aurora are expected to continue to rise through Friday, reaching a moderate flooding level of about 14 feet, officials said.

Flooding in both those areas is predicted to continue until as late as Saturday.

Officials said the Des Plaines River will also experience minor flooding starting early Friday morning and continuing through Tuesday. The DuPage River will see some brief minor flooding as well, with water levels peaking early Saturday and receding by Sunday, authorities said.

No-wake rules are in place on the Fox River and the Chain O' Lakes because of high water levels.

Anybody who's seen their kids' baseball games called off or their picnics scrapped knows that June also has been a wet month.

Through Wednesday, the city recorded 4.2 inches of rain for the month.

And the rain is expected to keep falling Friday. But the weekend should be mostly dry with highs in the 70s, according to AccuWeather.
