From 12 to 25 inches of snow fell over the San Bernardino mountains, from Wrightwood to Forest Falls. Over the Riverside County Mountains and the San Diego County mountains, snowfall ranged from eleven to eighteen inches. Heavy rain, between 1.6 and 3.2 inches, fell over the lower elevations. This caused flash flooding and mudslides along the lower slopes, foothill, and out into the valley floors and desert areas.
