The National Weather Service says there were 24 tornadoes on Monday in the Chicagoland area, a record number of tornadoes in a single day in the forecast area.

The National Weather Service (NWS) said on Friday that they had identified at least 24 tornadoes so far that occurred during severe weather on Monday.

Those included 14 EF-0 tornadoes, nine EF-1 tornadoes and one EF-2 tornado.

The NWS said this is a new daily record in the NWS Chicago forecast region.

The previous record was 22 on June 30, 2014, and again on March 31, 2023.

The NWS also reported there were at least six tornadoes, five EF-0 and one EF-1, that occurred last Sunday.

During the 48-hour period, at least 30 tornadoes occurred within the northern Illinois and northwestern Indiana area.

None of the tornadoes during the severe weather last Sunday and on Monday occurred in Lake or McHenry counties but both counties were under tornado warnings on Monday.

The fire district asked motorists to avoid the area and said ComEd was working to resolve the situation.

The NWS said tree damage was also reported in an area north of Algonquin.

A large tree came down onto wires in Lindenhurst, the NWS said.

The Lake County Division of Transportation (LCDOT) said the heavy rainfall led to flood roadways in Lake County, resulting in several road closures.

“Remember, TURN AROUND, DON’T DROWN. Just 6 inches of moving water can knock you down, and 2 feet of water can sweep your vehicle away,” LCDOT said.

LCDOT said Tuesday morning that roads in the county were “looking good” for the most part considering the intense rainfall.

“There will still be areas with some water on the pavement, and there may be a few signal outages,” LCDOT said.

The City of Highland Park reported around 11:30 p.m. Monday that multiple roadways in the city were blocked off with barricades due to flooding.

Over 200,000 ComEd customers in 30 counties had lost power as of 6:30 a.m. Tuesday and ComEd worked throughout this week to restore power.
