Dry north to northeast winds will increase through the morning on Sunday. Critical fire weather conditions are expected as relative humidity values fall into the single digits. These northeast winds will become stronger Sunday night, with peak gusts up to 60 mph possible, primarily over the exposed ridgetops of Lake and eastern Mendocino counties. Poor to very poor overnight humidity recoveries coupled with these gusty north/northeast winds will result in critical fire weather conditions across much of Northwest California. Very low humidity, breezy east to northwest winds, and dry fuels will result in critical fire weather conditions Sunday through Monday afternoon.
