Here are some of the other impacts seen around Chicagoland from the severe storms overnight:

Metra delays

Union Pacific Northwest inbound and outbound Metra trains were stopped between Jefferson Park to Cary due to high wind warnings from 4:45 p.m. until 5:45 p.m. Monday.

Ground stops at Chicago airports

The Federal Aviation Administration issued a ground stop for O’Hare International Airport just before 4 p.m. Monday, which lasted until 5:30 p.m.

Flights at Midway International Airport were grounded just after 4 p.m. Monday and also lasted until 5:30 p.m.

Overflow Action Day

The Metropolitan Water Reclamation District issued an Overflow Action Day during the storms, asking residents to minimize their water usage to help reduce flooding.

The MWRD asked residents to:

• Wait to wash clothes in the washing machine.
• Flush less.

These requests were made to ensure sewers don’t get backed and cause flooding into streets and basements.
