Extreme Heat Warning: High Temperatures Forecast Across LA County

LOS ANGELES, CA — High temperatures in the triple digits are forecast across Los Angeles County in the coming days, bringing excessive heat and fire weather conditions to the region, according to the National Weather Service.

Hot and dry weather is expected in the inland valleys, mountains and deserts, the NWS reports. Winds are expected to be gusty in the Antelope Valley area, with potential for large plume growth and extreme fire behavior. People are urged to report any smoke or fires, avoid yard work and save it for less humid or hot days.

The Los Angeles County Health Officer has issued an extreme heat warning for the following areas and days:

• Santa Clarita Valley: Saturday through Tuesday
• Antelope Valley: Saturday through Tuesday
• West San Fernando Valley: Sunday through Tuesday

A heat alert has also been issued for the following areas:

• East San Fernando Valley: Sunday through Tuesday
• East San Gabriel Valley: Sunday through Tuesday
• Los Angeles Basin: Monday through Tuesday

Interior valleys and mountains, excluding the Santa Monica Mountains, are expected to have temperatures up to 110 degrees. Antelope Valley will see temperatures up to 110 degrees. Santa Clarita will see temperatures up to 103 degrees.

"There is expected to be enough of an onshore push to keep a lid on temperatures in the other coastal valleys with Woodland Hills likely topping at or just short of 100," the NWS reports.

Warm overnight conditions are expected in these areas, according to the NWS.

"A significant warming trend will begin on Saturday, especially for inland areas where there will be widespread triple-digit temperatures Sunday through Wednesday," the agency reports. "Monsoonal moisture will likely move into the region next week and bring isolated showers and thunderstorms to the region."

People are urged to be cautious during this heatwave.

"Public Health reminds everyone to take precautions to avoid heat-related illness, especially older adults, young children, outdoor workers, athletes, and people with a chronic medical condition who are especially sensitive to negative health impacts from extreme heat," officials said.

Health officials urge people to drink plenty of water and stay hydrated during high temperatures days.

"If you must go out, plan your day to avoid going out during the hottest hours, and wear sunscreen," officials said. "Wear lightweight, light-colored clothes, and wear a hat or use an umbrella."

Cars can also get very hot and it's important to never leave children or pets in cars. Call 911 if you see a child or pet in a car alone, officials said.

"Beware of heat-related illness, like heat stroke and call 911 if you see these symptoms: high body temperature, vomiting, and pale and clammy skin," officials said.

It's also important to check on people who are at risk, including people who are sick, older adults, pregnant women and children. Watch out for people who live alone.

“While it is very important that everyone take special care of themselves, it is equally important that we reach out and check on others, in particular those who are especially vulnerable to the harmful effects of high temperatures, including children, the elderly, and their pets,” said Muntu Davis, MD, MPH, Los Angeles County Health Officer.

“High temperatures are not just an inconvenience, they can be dangerous and even deadly," Davis said. "But we can protect ourselves, our families, and our neighbors if we take steps to remain cool and hydrated."

Temperatures could rise to life-threatening levels and it's critically important to never leave kids alone in a vehicle, Davis said.

"If you have an elderly or infirm neighbor who is without air conditioning, check on them throughout the day," Davis said.

"If you are wearing a mask, avoid strenuous workouts wearing face coverings or masks not intended for athletic purposes," officials said.

You can also check your power company’s website or contact them by phone to determine if you are scheduled for a rolling power outage.

Cooling centers operated by the county and city will be open. Residents who do not have access to air conditioning are encouraged to take advantage of these free cooling centers. Visit the website to find a nearby location or call 211.
