The National Weather Service predicts a potentially dangerous heat wave in Southern California this weekend and into the week, with numerous places experiencing several days above 100 degrees.
A high-pressure system positioned over the four corners region is advancing westward, resulting in searing temperatures.
“We’re expecting warming temperatures each day leading to potentially dangerous heat risks by Sunday or Monday, continuing through most of next week,” Carol Smith, a Northwest Weather Service meteorologist, stated.
The Inland Empire will be one of the hottest areas.
Monday’s temperatures will be in the triple digits, according to meteorologist Philip Gonsalves. “Anywhere from 99 degrees to 108 degrees, depending on where you are in the Inland Empire.”
Temperatures in the Santa Clarita Valley will range from 102 to 109 degrees Fahrenheit, with peaks on Tuesday and Wednesday. Los Angeles residents should expect temperatures in the low to mid-90s, with a high of roughly 94 degrees on Tuesday. In Coachella Valley, temperatures can range from 110 to 117 degrees.
The heat wave is especially troubling for the Cal Fire/Riverside Fire Department, which is presently battling the Nixon fire near Aguanga.
“We have crews who are working long hours and staying out on the lines for extended periods,” Capt. John Clingingsmith said. “We make sure all the ice chests are filled with plenty of water and electrolyte-replenishing drinks and food to keep them going.”
The heat wave may be accompanied by thunderstorms. Firefighters are most concerned about lightning without precipitation, or dry lightning, which has the potential to cause more wildfires.
Clingingsmith emphasized the significance of registering for local emergency notifications. He advises that all Riverside residents register at RivCoReady.org.
In San Bernardino County, Health Officer Dr. Michael Sequeira issued a heat advisory, advising citizens to take precautions.
“Heat-related illnesses like heat exhaustion and heat stroke can be very serious, especially for those who are more vulnerable,” says Sequeira. “Being aware of summer heat isn’t just about staying comfortable; it’s about ensuring public health and safety.”
People can find air-conditioned public spaces by visiting San Bernardino County Cool Places to Go or calling the United Way’s toll-free resource line at 2-1-1. Seniors can also contact the Senior Information and Assistance Hotline at 1-800-510-2020.
Beachgoers drawn to the shore by warm temperatures should expect choppy surf in Orange County this week. Hurricane and tropical storm activity in Baja could generate enormous swells, which, although favorable to surfers at the U.S. Open in Huntington Beach this week, might be dangerous for others.
“The beach is beautiful, but the ocean is dangerous,” said Brian O’Rourke, Assistant Chief of Lifeguard Operations for the Newport Beach Fire Department. “When you foot onto the sand, you’re entering nature. Before entering the ocean, please check in with our lifeguards.”
