Dense Fog Advisory Issued for Central Ohio River Valleys This Morning
Patchy dense fog in Ohio river valleys creates hazardous driving conditions with rapidly changing visibility, weather service warns.

COLUMBUS, OHIO β Dense patches of fog covered central Ohio river valleys early this morning, leading the National Weather Service to issue a special weather statement warning drivers of rapidly changing visibility conditions.
The National Weather Service office in Wilmington issued the alert at 6:21 a.m. EDT on June 13, highlighting hazardous driving conditions in low-lying areas along rivers and streams throughout the region.
Driving Conditions Affected
The weather service specifically warned motorists to “remain alert for rapid changes in visibility” while driving this morning. The patchy nature of the fog means drivers could encounter sudden drops in visibility as they travel through affected areas.
River valley locations experienced significant fog development, with the weather phenomenon forming overnight as cool air settled into these lower elevations. The temperature differential between the warmer water surfaces and cooler air masses created ideal conditions for fog formation.
Safety Recommendations
Weather officials recommend drivers reduce speed and increase following distances when encountering foggy conditions. The patchy distribution means visibility can change dramatically within short distances, particularly as motorists transition between elevated roadways and river valley routes.
Morning commuters traveling along major highways that cross or parallel river systems should exercise extra caution during their journeys. The fog is expected to lift as temperatures warm throughout the morning hours.
The National Weather Service continues monitoring atmospheric conditions and will provide updates if the fog situation changes or expands to additional areas of central Ohio.
