“Red flag fire warnings are in effect for large portions of the West on Sunday and Monday, the National Weather Service said.
Strong winds and low relative humidity will cause a high risk that any fires that develop will spread rapidly.
Parts of the Sacramento Valley are under red flag warnings from 2 p.m. Sunday through 8 p.m. Monday. Southeastern California, as well as most of the neighboring states of Nevada and Arizona, are also posted. Strong west-to-southwest winds are expected to peak on the Sierra slopes Sunday afternoon and evening, and to weaken but remain near critical levels in northwest Arizona on Monday.
Although the most recent U.S. Drought Monitor showed little change this week in much of the West, fuels are dry, and drought conditions remain widespread.”
