Parts of Southern California received major rainfall yesterday as a reportedly once-every-thousand-year storm system hovered over the region and headed toward Arizona, prompting flood watches for millions. Rescuers have aided dozens of stranded residents in several counties around Los Angeles and Santa Barbara while the town of Oxnard recorded over 3 inches of rain in one hour. No deaths have been reported as of this writing.
The latest deluge adds to an already saturated California after last winter's nine atmospheric rivers—as well as August's rare Hurricane Hilary—pushed the state's overall water reservoir storage to nearly 130% of its historical average, snapping a decade of drought (see drought monitor). Roughly three-quarters of California's annual precipitation typically falls between December and February, but forecasters predict even higher levels this year amid the return of warmer, wetter El Niño conditions.
