A major heat wave is bearing down on Southern California, bringing some of the hottest temperatures of the year beginning Tuesday.
Here is what you need to know:
The hottest conditions will come Tuesday and Wednesday, with gradual cooling Thursday and into the weekend, meteorologist David Sweet of the National Weather Service’s Oxnard office said.
The weather service issued an excessive-heat warning from 10 a.m. Tuesday to 9 p.m. Friday in the mountains of Ventura and Los Angeles counties, not including the Santa Monica range.
Searing temperatures are expected in the inland parts of Los Angeles County, with Santa Clarita and Woodland Hills likely to reach 109 degrees Wednesday and Lancaster 111.
The coastline will also see unusually hot conditions, with 86 degrees expected in Ventura and Malibu on Tuesday and 97 predicted for Long Beach.
Some of the hottest temperatures are expected in the low-desert areas, including the Coachella Valley and Borrego Springs, which could see highs between 110 and 120 for the entire week.
Temperatures could break records and will clock in about 10 to 20 degrees above what’s typically recorded this time of year, said Alex Tardy, a meteorologist with the weather service’s San Diego station.
The winds are causing red flag conditions in southern Santa Barbara County, with gusts of 40 to 50 mph. And the low humidity, high heat and unseasonably dry fuels are creating an elevated fire risk, the weather service said.
Critically low moisture levels may have contributed to the eruption of the 400-acre Flats fire in the Santa Rosa Mountains on Sunday morning. The fire, which burned at least two homes, continues to threaten several mountain communities southwest of Palm Desert in Riverside County.
One firefighter was injured in the blaze, and officials are concerned the regional heat wave will complicate the fight to extinguish it.
To stay cool in the coming days, officials recommend the following:

Some general times from county health officials:
Many libraries, senior centers and community spaces around Los Angeles County are offering residents a free respite from the heat. Helen Chavez, associate director of the county’s Office of Emergency Management, recommended that people find a cooling center near them and call to ensure the hours posted online are correct.
Most Los Angeles public pools are also opening just in time for the heat wave, with availability from 2 to 6 p.m. Tuesday through Friday and 1 to 5 p.m. Saturday and Sunday, the city’s Department of Recreation and Parks announced.
Beginning next week, pool hours will change, with morning hours on weekdays. A complete list of pools, their addresses and hours can be found at the Department of Recreation and Parks website.
