SEATTLE -- October is typically the foggiest month for the area, and today, "Fogtober" is living up to its name.

Visibility is less than a quarter-mile in some parts of Western Washington Monday morning as dense fog has settled in the region.

A dense fog advisory is in effect until 11 a.m. for parts of Western Washington.

Visibility at most airports in the Puget Sound region was at about a quarter mile, except for JBLM-Ft. Lewis, which was even less -- an eighth of a mile.
