Dry heat is expected to persist in the Bay Area, with highest temperatures Monday.
Dry heat is expected to persist for the first half of the week as a heat wave rolls through the Bay Area.
Temperatures are likely to peak Monday, when thermostats could exceed 100 degrees in parts of the North, East and South Bay valleys, according to the National Weather Service.
Record-high temperatures were tied or exceeded Sunday in downtown San Francisco and at San Francisco and Oakland airports, as well as in Half Moon Bay and Monterey, the National Weather Service said.
The tarmac at SFO was so hot that the Jetway — the ramp-like bridge used to connect planes to terminals — created its own pothole and couldn’t come out to meet the plane. One United Airlines flight from Mexico City had to be towed to a different gate. In explaining the long delay, the pilot told the passengers, “If I hadn’t seen it with my own eyes, I wouldn’t have believed it.”
Other temperature records could be shattered by the continuing heat, said Steve Anderson, a National Weather Service meteorologist.
“It won’t be until the end of the week when temperatures are back to normal,” he said.
The National Weather Service issued a heat advisory for the San Francisco shoreline, North Bay valleys, East Bay valleys and Santa Clara Valley for 10 a.m. to 9 p.m. Monday.
San Francisco is expected to see temperatures in the upper 80s Monday, but forecasters said cooler weather could start as soon as Tuesday night, when the sunny skies are expected to subside in favor of fog and cooler weather.
Forecast highs could drop as much as 20 degrees over the next week, Anderson said.
Officials issued a Spare the Air alert through Monday, warning of worsening air quality because of rising temperatures.
Also complicating air quality forecasts was smoke from the Sand Fire in Yolo County, which had reached Marin County by Saturday evening, officials said. Forecasters said winds could push a thin stream of smoke over the North Bay as the blaze continues to burn.
Federal park officials canceled burn permits for Point Reyes National Seashore through Monday, and state officials shuttered access to the upper mountain of Mount Tamalpais State Park through Monday morning, citing critical fire danger.
