Residents of Wisconsin are advised to prepare for hazardous weather conditions as multiple winter storm watches are in effect across the state. Visibility may be severely reduced due to dense fog in the north central and central regions, potentially freezing on roads and creating slippery conditions. A potent winter storm is expected to hit the state, bringing heavy snowfall—with accumulations of up to 13 inches in some areas—and strong winds gusting up to 50 mph, leading to considerable blowing and drifting snow. Affected areas include, but are not limited to, Barron, Polk, Rusk, Manitowoc, Door, Kewaunee, Marathon, Portage, Wood, Langlade, Waushara, Menominee, Shawano, Waupaca, Calumet, Winnebago, Brown, Outagamie, Lincoln, Vilas, and Oneida counties. Travel is anticipated to be very difficult or impossible, especially during the Monday morning commute, with potential tree damage and power outages. Residents should stay informed, prepare to alter travel plans, and exercise extreme caution during this time.
