CHICAGO -- There are dangerous patches of ice everywhere you may be walking today -- on sidewalks, in alleys and in parking lots. It is slick.
After a two-day storm that left between 3 and 8 inches of snow across the area the temperatures have dropped today.
What was slush on roads last night, after being treated by city trucks is now ice.
The Department of Streets and Sanitation Commissioner said Sunday that ground temperatures were on his side. They were about 32 degrees, allowing the salt being spread to be really effective.
Those temperatures have gone down and those wet surfaces now have a frozen layer.
Many are having trouble navigating their way on foot outside their homes and apartment buildings and then to wherever they work.
Walk slowly, and be careful in parking lots where it can be really slick in the space between vehicles.
And the U.S. Postal Service is asking everyone not to forget their letter carriers when cleaning up all that snow and ice.
