Dense Fog This Morning

The National Weather Service has issued a Dense Fog Advisory for the Northern San Joaquin Valley through 11 AM this morning.

Areas of dense fog with visibility less than one-quarter of a mile have formed in the Northern San Joaquin Valley. This includes the lower, western portions of Tuolumne and Calaveras Counties.

A Dense Fog Advisory means visibilities will frequently be reduced to less than one quarter mile. If driving in fog, slow down, use your headlights and leave plenty of distance ahead of you.

Additionally, a Winter Storm Watch has been issued for the Sierra Nevada above 5,000 feet, from Friday afternoon through late Sunday night.

Snow levels will start above 8,000 feet on Friday before dropping below 4,000 feet on Sunday.

Total snow accumulations above the 5,000 foot elevation will range from five inches to two feet.

Winds of twenty-five to thirty-five mph are expected with gusts up to seventy mph.

Snow and wind may cause falling tree branches or limbs. These are dangerous conditions for hikers and campers. Expect travel delays this weekend, especially over the Sierra passes. There will be travel hazards due to snow covered, slick roads and blowing and drifting snow.

The winter storm will move through in two waves. The first wave of the storm arrives in Northern California late tonight. It will be wet and warm. This will be followed by a second cooler wave on Saturday and Sunday.

There is the possibility of urban and small stream flooding as well as debris flow near recent burn scars.

A Winter Storm Watch means there is a potential for significant snow that may impact travel.
