Strong winds fueled a wildfire near Interstate 5 north of Los Angeles on Sunday, prompting officials to caution residents in its path to prepare for potential evacuation if the blaze worsened.
Dubbed the Post Fire, Los Angeles County's first significant wildfire of the year rapidly expanded to cover nearly 23 square miles by Sunday evening, having grown substantially since forcing the evacuation of over 1,200 people from the Hungry Valley recreation area just a day earlier.
As of Sunday evening, containment of the fire stood at only 2%, with no reported injuries and the cause still under investigation.
Firefighters battled challenging conditions exacerbated by scorching temperatures and difficult terrain, struggling to extinguish spot fires that flared up as erratic winds carried burning embers ahead of the main flames. Aircraft attempting to drop water and fire retardant found their efforts hampered by gusts that dispersed their payload unpredictably.
Kenichi Haskett, a section chief with the LA County Fire Department, highlighted the difficulties faced by crews: "When it’s windy, it just sprays the water everywhere we don’t need it. So that’s a challenge."
Meanwhile, in Northern California, another smaller wildfire known as the Point Fire broke out near Lake Sonoma on Sunday, triggering evacuation orders and warnings for sparsely populated areas approximately 80 miles north of San Francisco. By Sunday evening, the Point Fire was 15% contained, having generated a substantial column of dark smoke as it burned through local vegetation.
The Southern California blaze ignited Saturday afternoon near Gorman, close to I-5, approximately 60 miles northwest of downtown Los Angeles. The fire, which led to the destruction of two structures within the evacuated recreation area, continued its advance towards Pyramid Lake, a popular boating destination closed as a precaution on Father's Day. While no residential areas were immediately threatened on Sunday, officials alerted Castaic's approximately 19,000 residents to be prepared for potential evacuation if the fire progressed southward.
Haskett advised residents in warning areas to prepare "go bags" containing essentials like overnight clothes, medications, glasses, and charged cellphones, emphasizing readiness to evacuate at short notice.
Weather conditions remained challenging, with low humidity and gusts up to 50 mph expected throughout the day, potentially increasing in strength after sunset, according to the National Weather Service's Los Angeles office.
About 75 miles to the east, the Hesperia Fire burned nearly 2 square miles since its outbreak on Saturday near mountain communities in San Bernardino County, prompting road closures and evacuation advisories. By Sunday evening, containment efforts had reached 20%.
Authorities continued to monitor and respond to both the Post Fire and other blazes across the state as fire season intensified with the onset of hot, dry weather conditions.
