Moderate HeatRisk - Interior Bay Area/North Bay

Gusty Wind Potential through Monday

A warming trend is anticipated toward the middle/end of next week. High temperatures are forecast to climb into the mid to upper 90s across interior portions of the Bay Area (East Bay and southern Santa Clara Valley). This level of heat affects most individuals sensitive to heat, especially those without effective cooling and/or adequate hydration. Impacts possible in some health systems and in heat-sensitive industries.

Northwest winds of 20-30 mph with gusts to 45 mph are forecast through Monday especially across coastal areas of North Bay, parts of the East Bay, gaps, passes, and valleys (i.e., San Bruno Gap, Altamont Pass, Salinas Valley). Be sure to secure loose outdoor objects, be alert when driving (especially high profile vehicles). Also beware of downed tree limbs or trees. Finally, the elevated winds could help fuel a grass/brush fire.
