As of 11 p.m. Tuesday, temperatures hovered around 32 degrees. Freezing rain was collecting on trees and bushes, as well as forming a layer of glaze on untreated surfaces such as streets, sidewalks, driveways, parking lots and vehicles. Treated roads and highways can also have slick spots. Travel or outdoor activities will continue to be very hazardous. The last time there was an Ice Storm Warning in the Chicago area was December 2009. Roadways were iced over, making for dangerous road conditions. Power lines were pulled down, as ice accumulations can increase the overall weight held up by the lines by up to 500 pounds. Just a quarter of an inch of ice can increase the weight of a tree branch by up to 30 times. “It’s been a long time so people, their guards down, they haven’t experienced it,” said Joe Lomanto, the owner of Lakeview Ace Hardware. “So really hold on to railings, know where you’re going, you may once again not see it, and with black ice you could really go down quickly.” By 11 p.m., the heaviest rains and embedded thunder had mostly moved east or were in the process of moving east into northwest Indiana. Light freezing rain and drizzle will likely continue for several hours. Ice accumulations of a quarter-inch or more will be widespread. The highest ice accumulations will be north and west of a line from near Mendota to Oswego. If you need to drive, be cautious into the morning hours. The morning commute will likely impacted. Drive slowly and be alert for others not being able to stop or retain footing.
