Meanwhile, a Wind Advisory has been issued for the Mother Lode and the Northern San Joaquin Valley until noon today.
Winds of fifteen to thirty mph will continue with gusts ranging from forty to fifty mph.

Additionally, a Flash Flood Warning has been issued for southeastern Tuolumne County and central Mariposa County until 9:15 AM this morning.
There has been heavy rain at times over the burn scar area.
Excessive rainfall over the burn scar will cause mud slides near steep terrain. Flash flooding and debris flows are likely. The mud slide can consist of rock, mud, vegetation, and other loose materials.
An overall Flash Flood Watch remains in effect for Mariposa County through Friday morning.
The hazardous conditions could impact the morning or evening commute.
Instructions: Move away from recently burned areas. Life-threatening flooding of creeks and roads is likely. The heavy rain will likely trigger rockslides, mudslides and debris flows in steep terrain, especially in and around these areas. Move to higher ground now. Act quickly to protect your life.
A Flash Flood Watch means that conditions may develop that lead to flash flooding. Flash flooding is a VERY DANGEROUS SITUATION. You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued.
A Wind Advisory means that winds of 25 to 40 mph are expected. Winds this strong can make driving difficult, especially for high profile vehicles. Use extra caution.
