Another hot weekend is bearing down on Southern California, and this one comes with a fire-weather edge, LAist reports. Here is what to expect and how to handle it.
The forecast
The heat peaks Sunday and holds into at least Monday. Inland, that means the mid-90s to about 105 degrees across the San Fernando and San Gabriel valleys and other inland parts of L.A. County, up to 108 in the Inland Empire, and up to a brutal 120 in the Coachella Valley.
The coast and the urban core fare better. Downtown Los Angeles, Orange County, and Ventura and Santa Barbara counties should sit in the low 90s, and the beaches in the low 80s, the usual Southern California split in which a few miles of distance from the ocean is worth many degrees.
The National Weather Service has a heat advisory up for much of the region through Monday, and a more serious extreme-heat warning for the Inland Empire and Coachella Valley.
Why the fire risk rises with it
Heat alone does not start fires, but this pattern stacks the conditions that let them spread. The same high-pressure system driving the temperatures also brings downslope winds and dry air away from the coast, and the vegetation is already parched. UCLA atmospheric scientist Rong Fu described the setup: "We have humidity, but it's not reaching the saturation point. Therefore, we won't have a cloud. We won't have precipitation." Dry fuel, low humidity and wind are the ingredients, and the weekend supplies all three inland.
Worth remembering, and the reporting stresses it, is that the biggest wildfire risk is not the weather but people: improperly extinguished campfires and other human carelessness are among the most common ignition sources. The dry hills do not catch by themselves.
Staying safe
The practical guidance is the standard hot-weekend checklist, and it matters most for the people most exposed. Outdoor workers, older adults, young children, and anyone without air conditioning are at the highest risk from the heat itself, and should limit exertion, hydrate, and find cooled spaces during the peak hours.
At the beach, the danger shifts from heat to water: forecasters warn of dangerous rip currents and swells, so swimmers should stay near lifeguards and steer clear of jetties and tidal rocks. And inland, the fire-safety math is simple, be scrupulous with anything that can spark, because on a weekend like this the margin for error is thin. The Herald will update if the weather service escalates the warnings or a fire breaks out.
