Daniel Swain for SFist — One Last Storm to Come Before Rainy Season Officially Ends Sunday

UCLA climate scientist Daniel Swain discusses California’s rainy season for SFist, sharing how the ‘above average’ snowpack in the Northern Sierra is notable due to the region’s shifting weather patterns. Swain emphasizes the unpredictability of future rainfall trends, noting that extremes are becoming more common. “It’ll be everything but the mean that matters,” Swain added, explaining that mean trends become meaningless if California starts swinging between extremes from year to year.
