Residents in Minneapolis faced reduced visibility today, as a dense fog advisory remained in effect until noon, as per the National Weather Service Twin Cities/Chanhassen MN. Travelers were advised to exercise caution due to visibility dropping to a quarter mile or less in some areas. Conditions were exacerbated wherever temperatures fell below freezing, leading to a deposition of freezing fog that created slippery spots on roads, “especially bridges and overpasses,” according to the Hazardous Weather Conditions forecast.
