The National Oceanic and Atmospheric Administration, or NOAA, issued a “red flag” warning on Monday, which will stay in effect until 5 a.m. Wednesday morning.
According to the warning, which encompasses the North Bay mountains, East Bay Hills and the Diablo Range, northeast winds are expected to reach 10 to 25 mph, with some gusts reaching up to 35 mph.
The warning also states that the region is expected to experience high temperatures and low levels of humidity. Under these conditions, any fires that develop are likely to spread rapidly.
The warning is especially targeted at the North Bay mountains, as well as the peaks and ridges in Napa County since these regions are at the greatest risk.
