A winter storm is expected to sock the region Sunday with more than a quarter of an inch of ice.
The National Weather Service has issued a winter storm watch for Cook, Will, Lake, Porter, Newton, Jasper and Benton counties from Sunday morning through late Sunday night.
The storm is expected to begin as freezing rain mixed with sleet Sunday morning and change over to rain Sunday night from south to north across the region as temperatures gradually rise above freezing.
The National Weather Service forecasters warned that ice accumulating on tree limbs and power lines could weigh them down. Ice on power lines coupled with increasing wind speeds could result in power outages.
Pavement and soil temperatures are below freezing, meaning any liquid precipitation will likely freeze on contact and result in icy, dangerous travel conditions on untreated roadways, forecasters said. Sidewalks and walkways could become dangerous for pedestrians as well.
The storm is expected to begin later Sunday afternoon in LaPorte County.
