A freezing fog advisory remains in effect until 11 am MST this
Dense fog along Interstate 15 from Blackfoot to Pocatello and
Interstate 86 from Pocatello west towards Burley will continue
to reduce visibilities to one quarter mile or less in many areas.
With temperatures below freezing... slick spots are likely on area
roadways. The fog is expected to improve by lunch time.
A freezing fog advisory means visibilities will frequently be
reduced to less than one quarter mile. If driving... slow down...
use your headlights... and leave plenty of distance ahead of you.
Also... be alert for frost on bridge decks causing slippery roads.
