Quad Cities, IA/IL – Drivers across eastern Iowa, west central Illinois, and parts of northeast Missouri should prepare for hazardous travel conditions tonight as dense fog blankets the region. The National Weather Service in the Quad Cities has issued a Dense Fog Advisory in effect from 9 p.m. Sunday through 9 a.m. Monday, warning of sharply reduced visibility in several areas.
According to the advisory, visibility could drop below one-quarter mile at times, especially south of a line from Independence, Iowa, to Galesburg, Illinois. The fog may persist through the early morning hours, potentially disrupting Monday’s commute across key travel corridors including I-80, I-74, and U.S. 34.
Meteorologists advise drivers to slow down, increase following distance, and use low-beam headlights when encountering fog. Using high beams can worsen glare and reduce visibility even further.
At 60 mph, drivers have just over one second to react when visibility drops to 100 feet, according to NOAA. Motorists are urged to remain cautious, especially in rural and low-lying areas where fog tends to form thickest.
The advisory comes as calm winds and overnight temperature drops create ideal conditions for fog development across the Mississippi River Valley. Conditions should gradually improve by mid-morning Monday as the fog lifts.
