San Bernardino County Fire Department Battalion Chief 141 assumed incident command for heavy debris flows and flooding in Wrightwood on December 24, 2025, reporting Highway 2 impassible, requesting additional engines, hand crews, dozer and swift water rescue, and evacuating impacted homes, according to an X post shared between 4:45 p.m. and 5:16 p.m. UTC. @Weathertrackus described an intense firehose of heavy rain with embedded strong storms causing significant flash flooding and locally severe wind gusts across areas between Santa Maria and San Bernardino, especially higher elevations, warning of potentially catastrophic flooding during the same 30-minute window and urging avoidance of flooded areas. These developments follow National Weather Service reports of very heavy rain and ongoing flooding in the San Bernardino County Mountains earlier in the afternoon, as shared in X posts before 4:45 p.m. UTC, amid a powerful atmospheric river impacting Southern California.
