The Des Moines offices of the National Weather Service (NWS) has issued a dense fog advisory until 10 a.m. Monday.
Visibility is expected to remain below one-half mile, with widespread one-quarter mile visibility through mid-morning. The NWS predicts visibility will begin to improve by mid- to late-morning.
Areas east of U.S. Interstate 35 and north of U.S. Highway 30 may see improvement shortly after sunrise, but commuters farther south and west will face lower visibility until mid- to late-morning.
Motorists are advised to slow down, use their headlights and leave plenty of distance ahead of their vehicles because low visibility in dense fog makes for limited sight distance and hazardous travel.
In addition, the NWS notes many locations are at or below freezing, and the dense fog may leave a layer of glaze on the untreated roadways. Roadways may be slick during the morning commute, and motorists are advised to drive carefully.
