ChicagoShovels.org, bookmarked, if only to see the radar map and weather forecast. There's also an improved map that will show the city snowplows' progress ("Plow Tracker").
The city has also sent out a reminder of landlords' obligation to keep tenants' units heated in the winter:
"The Chicago Heat Ordinance mandates that landlords supply heat to rental units during cold weather months. From September 15 to June 1, the temperature inside a rental residence must be at least 68 degrees during the day. During the evening, the temperatures must be at least 66 degrees. The Department of Buildings encourages residents to first contact their landlords when these temperatures are not maintained and to call 3-1-1 if no action is being taken. During extreme cold weather, however, the Building Department’s first priority is responding to heat complaints and it reassigns inspectors to handle the increased number of heat complaints."
Welcome to another exciting winter, folks.
