Red Flag Warning for the North and East Bay Hills, as well as the East Bay Interior Valleys, through 6 pm Tuesday for offshore winds and low humidity.

The Red Flag Warning has been extended through Tuesday afternoon. Conditions have briefly moderated but offshore winds will gradually increase again Sunday night into Monday morning across the North and East Bay hills. 

The latest forecasts now suggest conditions will worsen Monday night into Tuesday morning as another burst of strong offshore winds develops in the hills. This will occur with very low humidity values and drought stressed fuels. Winds will ease through the day Tuesday but warm and dry weather will persist through the Tuesday afternoon burn period.
