Rainless thunderstorms could sweep through the Bay Area today and tomorrow, prompting local firefighters to issue a "red flag warning" for fires.
Despite the morning sunshine and blue skies (in Oakland at least), the weather forecast is claiming there could indeed be some thunderstorms over the next couple of days, especially in the north, east, and south bays. And although these storms aren't expected to produce rain, you could see some lightning -- and that doesn't mix well with dry conditions.
Thus, the red flag warning.
Here's the National Weather Service's all-cap warning:
GUSTY WINDS AND LIGHTNING ARE POSSIBLE THROUGH THE PERIOD. THUNDERSTORMS MAY INITIALLY BE DRY BUT SHOULD BECOME WETTER WITH TIME. STRONGER STORMS MAY PRODUCE ABUNDANT LIGHTNING AND SMALL HAIL. OUTFLOW WINDS: SPEEDS TO 25 MPH ARE POSSIBLE NEAR THUNDERSTORMS. DRY FUELS ALONG WITH THE POTENTIAL FOR ABUNDANT LIGHTNING MAY RESULT IN NEW FIRE STARTS EVEN WITH STORMS THAT ARE WET. A RED FLAG WARNING MEANS THAT CRITICAL FIRE WEATHER CONDITIONS
ARE EITHER OCCURRING NOW...OR WILL SHORTLY. A COMBINATION OF DRY
FUELS AND LIGHTNING STRIKES COULD RESULT IN NUMEROUS FIRE STARTS
ABC News reports that fire officials are prepping to haul in additional resources in the event that lightning causes some fires. The red flag warning went into effect Sunday and will remain until Wednesday.
