Hot conditions and Santa Ana winds are set to hit Southern California this week, marking the start of the fall wildfire season as the region continues to recover from January’s devastating firestorms.
Although no red flag warnings have been issued yet, the Santa Clarita and San Fernando Valley foothills will experience elevated fire risks once the winds arrive, according to National Weather Service meteorologist Rose Schoenfeld.
The warming trend is expected to begin between Monday night and Tuesday morning when the winds shift into a Santa Ana pattern, Schoenfeld said. Temperatures across much of the Los Angeles Basin and Santa Clarita Valley will reach the upper 80s and low 90s, which is 10 to 15 degrees above normal for this time of year.
The winds will mostly be confined to the Los Angeles County mountains and foothills, she added.
In response, the National Weather Service has issued a heat advisory for Los Angeles County, Orange County, and the Inland Empire from 10 a.m. Tuesday until 7 p.m. Wednesday.
Tuesday and Wednesday are expected to be the hottest days, with temperatures in the mid-80s. Warm temperatures will continue through the end of the week, with highs ranging from the upper 70s to mid-80s on Thursday and Friday.
As wildfire season approaches, Schoenfeld recommends that residents in high fire risk areas review their evacuation plans and prepare a go-bag containing essential items. Staying prepared is crucial to ensuring safety during this challenging period.
