Red Flag Warning in the Bay Area on August 15, 2020.
The entire San Francisco Bay Area and surrounding regions will be under a red flag warning issued by the National Weather Service due to the current heat wave and the potential for dry lightning.
The red flag warning starts at 4 p.m. in Monterey and San Benito counties, and at 11 p.m. in all other counties. It is slated to expire everywhere at 11 a.m. Sunday.
"Moist unstable air will bring a slight chance for fast moving high based storms with little to no accompanying wetting rains," the National Weather Service warns. "This air mass will move roughly from south to north beginning in the Central Coast this afternoon/evening before transitioning into the Bay Area overnight into early Sunday. Given dry fuels and hot dry conditions near the surface, dry lightning can directly lead to wildfire starts."
In addition, the NWS warned that, "Onshore winds near the coast late Saturday may lead to additional complications for any fire starts in proximity to the sea breeze."
The region was originally under a fire weather watch, but it was upgraded to a red flag warning at 11 a.m. Three hours earlier, the NWS shared that lightning was already developing over Santa Barbara and San Luis Obispo counties.
The Bay Area saw triple-digit temperatures in many places on Friday, and temperatures will remain high on Saturday, with a large portion of the Bay Area under an excessive heat warning.
Heat hazards for Saturday, August 15, 2020.
On Friday, climate scientist Daniel Swain of Weather Watch warned that California's heat wave "will be more intense, prolonged, and dangerous than previously anticipated."
"A very intense and prolonged heat wave now appears likely for a large portion of California over the next 7-10 days, and this event will likely have wide-ranging impacts from human health, wildfire, and electricity demand perspectives," he wrote. "I suspect this event will probably end up being one of the most significant widespread California extreme heat events in the past decade, if not longer."
The heat wave has strained California's electrical system, with the The California Independent System Operator (California ISO), directing utilities around the state to implement rolling power outages.
