The Chicago Tribune is reporting that over 1,000 Chicago-area flights have been cancelled. More than 850 flights out of Chicago O'Hare International have been cancelled and Midway Airport has cancelled at least 230 flights.
The cancellations come as a winter storm is beginning to drop snow on the city. The U.S. National Weather Service (NWS) is predicting up to 12 inches of snow could fall the Chicago area today.
The NWS has also issued a winter storm warning and a hazardous weather outlook for the greater Chicago area that lasts until midnight. From the NWS warning:
A WINTER STORM WARNING FOR HEAVY SNOW MEANS SEVERE WINTER WEATHER CONDITIONS ARE EXPECTED. SIGNIFICANT AMOUNTS OF SNOW ARE FORECAST THAT WILL MAKE TRAVEL DANGEROUS. CONSIDER ONLY TRAVELING IF IN AN EMERGENCY. IF YOU MUST TRAVEL...KEEP AN EXTRA FLASHLIGHT... FOOD...AND WATER IN YOUR VEHICLE IN CASE OF AN EMERGENCY.
Schools throughout Chicago were closed or closed early today. The Tribune report states that the Chicago Department of Streets and Sanitation has been salting the roads in and around the city since early this morning, and the Illinois Tollway has snowplows standing by.
