Temperatures will remain hotter than normal in the Southland for the foreseeable future, with dangerously hot weather expected by next weekend, forecasters said Monday.
An extreme heat warning was in effect until at least 8 p.m. Monday in Lake Los Angeles, Lancaster and Palmdale, which were roasting under triple-digit highs. A less severe heat advisory was issued for other areas of the county for the same period.
“Southern California, and for that matter most of the West, continues to roast under temperatures that are 5-10 degrees above normal and abnormally high humidities due to ocean temperatures that are also 4-8 degrees above normal,” the National Weather Service said Sunday.
That pattern was not expected to change much the rest of the week, with very slight cooling of a couple degrees possible Tuesday and Wednesday before another spike sends temperatures way above normal levels next weekend.
Downtown Los Angeles is expected to see highs of 90 and 92 degrees next Saturday and Sunday, the NWS said. Pasadena, Van Nuys and Woodland Hills will all crack 100 degrees on Saturday, while Valencia will reach 105 and Lancaster will reach 111, according to current forecasts.
In Orange County, Anaheim is expected to surpass 90 degrees Friday and Saturday.
Temperatures near the coast will offer the most relief, staying in the 70s all week.
Overnight lows will remain elevated all week too, remaining in the upper 60s in most valley areas.
“The hot and humid conditions during the day and night will bring elevated risks of heat-related illness,” the NWS advised.
The city of Los Angeles urged residents to take precautions during the heat event by staying hydrated, seeking shade or air-conditioned buildings and limiting strenuous outdoor activities to the morning or evening hours whenever possible.
People without access to air conditioning were encouraged to seek relief at public libraries, recreation facilities, senior centers or other public buildings. Information about cooling centers is available by calling 311 or online through the city’s emergency management website at emergency.lacity.gov/heat.
People were reminded to never leave children or pets in a parked vehicle for even a minute on hot days, as inside temperatures can rapidly reach deadly levels.
