AREAS OF DENSE FOG THIS MORNING... Patchy dense fog has developed across portions of the region this morning. Fog is reducing visibility to less than 1 mile in most places with a few locally dense spots. Motorists should use caution if out driving and be prepared for sudden changes in visibilities. Do not assume the road ahead is unobstructed. Use low beam headlights, and leave plenty of distance between your vehicle and others. Additionally, given the recent snowmelt and rainfall, be alert for high water in the typical low-lying trouble spots.
