Bay Area Faces a Weather ‘Quadfecta’: Heat, Fire Risk, Flooding and Powerful Waves

Key Points:

• Inland areas in the Bay Area will experience high temperatures ranging from the 80s to triple digits on Wednesday and soaring into the 90s or low 100s by Thursday, with rural Contra Costa County potentially reaching 105 degrees.
• A heat advisory is in effect from noon to 11 p.m. Thursday for multiple regions including the North Bay, Sonoma coastal range, East Bay, Santa Clara Valley, and San Francisco Bay shoreline, though the heat event is expected to last only about two days.
• A red flag warning is issued from 11 p.m. Wednesday to 9 a.m. Thursday for North and East Bay interior and mountain areas due to hot, dry, and windy conditions, with strong winds up to 60 mph at high elevations increasing fire risk.
• Coastal flood advisories are in place starting Wednesday evening for the North Bay and expanding Thursday for the rest of the Bay Area, as high astronomical tides combined with a half-foot surge could cause minor flooding, especially in Marin County.
• A beach hazards statement warns of increased risk of dangerous sneaker waves and rip currents along southwest-facing Pacific Coast beaches through early Thursday, urging beachgoers to remain vigilant due to the sudden and unpredictable nature of these waves.
