The following is a post from the Mendocino National Forest’s Facebook page:

ROAD CONDITIONS UPDATE: Please wait until the weather clears and roads dry out before heading into the forest. We have received reports of vehicles stuck in freezing temperatures for several hours.
This week’s storms have brought snow, ice and downed trees. In some areas the snow level has reached down to 2,800 ft. Another winter storm is expected to arrive tomorrow, Saturday-Monday.
In addition to safety concerns, driving over excessively wet, muddy or frozen areas in the winter damages the road surface, and costs thousands of dollars per mile to resurface. One foot of snow is enough for a vehicle to get stuck.
Roads are not plowed or maintained through the winter and may be impassable in different locations. You can check our road conditions page for more info, but know that road conditions could change at any time: bit.ly/3izH25a
