Dense fog could create hazardous driving conditions in some parts of the Ann Arbor area this morning, the National Weather Service warns.

The weather service has issued a dense fog advisory in effect until 11 a.m. Monday. Fog could reduce visibility to a quarter mile or less, the weather service said.

Drivers are advised to slow down, use headlights and leave plenty of distance between vehicles.

Once the fog clears, another unseasonably warm day is in store with partly sunny skies and a high near 80 degrees.
