La Crosse, Wisconsin – Drivers across northeast Iowa and southwest Wisconsin are waking up to hazardous travel Monday morning as dense fog sharply reduces visibility to a quarter-mile or less in many areas.
According to the National Weather Service in La Crosse, visibility has dropped rapidly due to patchy dense fog spreading across the region. The worst conditions are centered in northeast Iowa and southwest Wisconsin, with variable travel conditions expected to persist through 9 to 10 a.m.
Major roads like U.S. Route 52 and Wisconsin Highway 35 may see dangerously low visibility, especially in low-lying areas or near rivers. Motorists are urged to slow down, turn on low-beam headlights, and leave extra space between vehicles. Law enforcement and emergency officials report increased risk of collisions during fog events like this.
Travelers should prepare for delays and avoid sudden stops on highways. This morning’s fog follows a humid overnight period, and similar patterns could repeat this week if evening temperatures remain cool and moist.
Conditions are expected to improve mid-morning as the sun burns off the fog, but additional advisories may be issued if visibility does not improve as forecasted.
