Des Moines, IA – Dense fog is expected to blanket much of Iowa overnight, creating hazardous travel conditions through early Sunday morning as visibility drops below half a mile in several areas.
According to the National Weather Service in Des Moines, areas of dense fog will develop tonight and persist into Sunday morning, with visibilities falling to a half mile or less, especially before sunrise. Drivers across Polk, Story, Dallas, and surrounding counties are urged to use extreme caution if traveling overnight or early Sunday, as sudden drops in visibility could impact highways such as I-35 and I-80.
Local officials recommend delaying non-essential travel until after sunrise. If you must drive, slow down, use low-beam headlights, and leave extra distance between vehicles. Early morning commuters should be prepared for patchy, dense fog in both rural and urban areas, especially along rivers and low-lying valleys.
Fog is expected to steadily dissipate after sunrise as temperatures rise, with clearer conditions returning by late Sunday morning. Additional advisories may be issued if fog lingers or intensifies. Stay tuned for the latest updates from the National Weather Service.
