A hotter finish to the weekend is in store with inland temps soaring into the 90s for Sunday. We ll also see a Spare the Air day with unhealthy ground level ozone levels in the East Bay valleys. By the evening out attention turns to increasing dry lightning potential which has activated a Red Flag Warning for higher elevations throughout…
A chance of dry lightning hitting the Bay Area today and Monday has prompted the National Weather Service to issue a red flag warning for fire danger, a forecaster said.
The low-pressure front moving into the region as early as this afternoon brings a chance of showers, isolated thunderstorms and dry lightning through Tuesday, National Weather Service forecaster Bob Benjamin said.
Lightning strikes combined with extremely dry conditions across inland hills and valleys could bring significant fire danger, prompting the red flag warning for counties in the North and East Bay across San Mateo County to the Santa Cruz Mountains, Benjamin said.
Though there is a 20 to 30 percent chance of rain accompanying the front, there is "little chance of rain ever hitting the surface," Benjamin said.
Cal Fire has said additional firefighters will be placed on duty during the heightened fire danger.
The red flag warning goes into effect at midnight tonight and will remain in effect until noon on Tuesday.
