As a heat wave ramps up around the Bay Area on Monday, an excessive heat warning is in effect for much of the region and forecasters also have issued a fire weather watch for parts of Monterey County that starts Wednesday.
Dangerously hot conditions are expected, with inland temperatures up to 110 and highs of 95 along the coast, according to the National Weather Service.
Overnight lows will range from the lower 70s to lower 80s.

The excessive heat warning, effective through 11 p.m. Wednesday, covers North Bay interior areas and coastal ranges; the San Francisco Bay shoreline; interior East Bay areas; Santa Clara County; the Santa Cruz Mountains; and interior Monterey County.
A heat advisory has also been issued for other parts of the Bay Area, including coastal areas, through 11 p.m. Wednesday.
A fire weather watch has been issued for parts of Southern Monterey County, from 6 a.m. Wednesday until 8 p.m. Thursday.
“Critically dry fuels and gusty offshore winds will lead to increased chances for fire starts and fire spread,” the weather service said.
Heat wave triggering power shutoffs
During the heat wave, people and pets should not be left in cars without air conditioning, and outdoor outdoor activities should be limited for those who are sensitive to heat, and people should stay hydrated.
High winds and dry conditions during the heat wave that’s toasting the Bay Area this week may bring public safety power shutoffs for customers in four counties around the region, the power agency said Monday.
Those notified of possible power shutoffs include 286 customers in Contra Costa County, 140 in Napa County, 57 in Alameda County and 11 in Sonoma County, according to PG&E spokesperson Tamar Sarkissian.
“We continue to monitor the weather in those areas,” Sarkissian said.
The power shutoffs could take effect between 6 p.m. Monday and 11 a.m. Tuesday.
Nearly 10,000 customers in some Northern California counties are already undergoing power shutoffs due to the ongoing heat wave affecting a large portion of California. Most are in Shasta County, where nearly 8,000 customers are affected, Sarkissian said.
