...PATCHY DENSE FOG ACROSS THE PORTLAND/VANCOUVER METRO THIS
MORNING...

Patchy dense fog limiting visibility to one mile or less has
developed across western portions of the Portland/Vancouver metro
this morning. Eastern portions of the metro including Gresham,
Troutdale, Fairview, Camas, and Washougal are less likely to see
travel impacts from reduced visibility.

Fog may not be uniformly dense and commuters should expect rapid
changes in visibility on area roadways. Dense fog is most likely
to occur in areas sheltered from winds as well as areas near
waterways including lakes and rivers. Locales less sheltered from
winds may instead see low overcast skies where only hilltops
experience reduced visibility.

Drivers should slow down and leave plenty of following distance.
Pedestrians and cyclists should wear bright or reflective clothing
to increase the chances of being seen by others in poor visibility
conditions.
