Warm weather will gradually build across the Bay Area this week, with inland communities facing increasing heat and elevated fire weather concerns, and dangerous beach conditions even as cooler temperatures persist near the coast. Moderate HeatRisk is expected to develop across many interior locations beginning Thursday and continue into the weekend. Forecasters said the hottest days are expected on Saturday and Sunday, when interior parts of the North Bay, East Bay and South Bay could see highs in the upper 80s to near 100 degrees. AdvertisementFire danger will also remain elevated through midweek across the Diablo Range, Santa Lucia Range and other inland areas because of hot temps, low daytime humidity, breezy afternoon winds and only limited overnight moisture recovery. Along California’s Pacific coast, hazardous beach conditions are expected to continue through at least Saturday, with an increased risk of sneaker waves and strong rip currents.
