Airlines cancel more than 280 flights at O’Hare

Airlines at O’Hare Airport Tuesday canceled more than 280 flights due to poor weather conditions on the East Coast, the Department of Aviation said.

About 45 flights have been canceled at Midway Airport, the department said.

Neither airport is experiencing delays.

The blizzard, expected for several states on the East Coast, is expected to drop anywhere from 18-24 inches of snow between Monday and Wednesday, the National Weather Service said.

Meanwhile, the city redeployed its full fleet of 280 plows to salt neighborhood streets early Tuesday ahead of the morning commute, which could be impacted by overnight freezing rain.

Switch problems caused delays on Metra’s Union Pacific/North Line Tuesday morning. Train No. 309, which was scheduled to arrive in Kenosha at 8:18 a.m., is running 18 to 23 minutes behind schedule because od switch problems at Lake Street, Metra said in a service alert on its website.

A freezing rain advisory was in effect for all Chicago-area counties in Illinois counties until 6 a.m., the National Weather Service office in Romeoville said.

Less than a tenth of an inch of ice was expected to accumulate overnight, but that’s still enough to leave untreated roads and walkways slippery, the weather service said.
