Unseasonably warm weather in the Bay Area is expected for the next several days, according to the National Weather Service.
Each day this week the temperatures is expected to steadily rise, with Thursday being the warmest day.
Highs are likely to be near record-setting levels with interior locations in the 90s, according to forecasters.
A strong ridge of high pressure over California will produce the hottest temperatures in the valleys of southern Monterey County. Temperatures there may reach 100, the NWS said.
The coast will be cooler but may reach 85 degrees. Overnight lows along will be between 50 and 60 in most locations.
Temperatures are expected to cool considerably by Friday, the NWS said.
People working outdoors are encouraged to use caution, take frequent breaks, try to avoid being outside during the hottest times of day, and drink plenty of water. Residents are encouraged to check on friends, neighbors and relatives during severe heat waves, the NWS said.
Residents are reminded not to leaving children or pets in an unattended vehicle, even with the windows rolled down.
While wind does not yet appear to be strong enough to create a significantly elevated risk of wildfires, residents should remove flammable vegetation located within 30 feet of their homes, according to CalFire.
