CHICAGO (CBS) — The National Weather Service has issued a Freezing Rain Advisory which expires at 9 p.m.

According to CBS 2’s Ed Curran, the storm will create freezing rain that will create a coating of ice that could amount to a one to two tenths of an inch. According to the NWS, pavement and soil temperatures are below freezing, so any rain will likely freeze on contact. The ground will warm up during the evening hours and freezing rain will become rain.

Curran warned of hazardous travel, tree limbs in danger and power lines.

Freezing rain can lead to power outages, and Comed Spokeswoman Arlana Johnson says Comed has been getting ready.

“We will have additional staffing at our operations facility, which is responsible for dispatching the crews to locations to address outages,” said Johnson. “In addition to that, we do have additional crews that are on standby today.”

Johnson says Comed is expecting about a quarter inch of ice accumulation, enough to disrupt power.
