The combination of an unseasonably moist air mass, light winds and some decrease in cloud cover is resulting in areas of dense fog across northern Indiana. That has prompted the National Weather Service in Northern Indiana to issue a dense fog advisory for Kosciusko County.

The advisory is in effect now until 11 a.m. Monday.

With dense fog, visibility will be to one quarter of a mile or less. Fog should begin to dissipate by late morning.

Other counties with dense fog advisories are Marshall, Whitley, Elkhart and St. Joe.
