dense fog advisory
Thick mist alert
A dense fog advisory is a weather alert issued when fog reduces visibility to a quarter mile or less over a widespread area.
It warns drivers and pilots of hazardous conditions: The National Weather Service issued a dense fog advisory for the valley through mid-morning.
Unlike a fog warning, an advisory indicates conditions that are inconvenient and potentially dangerous but not extreme.
