(Salt Lake City-AP) -- A dense fog is blanketing most of Utah this morning.
The National Weather Service has issued a dense fog advisory for the Wasatch Front including Salt Lake and Tooele Valleys. There's also a dense fog advisory in the southeastern part of Utah for Grand Valley as well as west central Utah for Sanpete and Sevier Valleys.
The fog is making for very low visibility and motorists should leave more time in their morning commute.
Most of the fog should lift by late morning into the early afternoon, but the National Weather Service says the heavy fog could return tonight and again Friday morning.
