| Episode narrativeepisode_narrative | A moisture plume with a weak atmospheric river arrived on December 5th and brought rain to the region. On December 6th, a strong closed upper level low pressure brought an unstable air mass into Southern California with showers and thunderstorms, especially Orange and San Diego Counties. Rainfall of 1 inch per hour amounts occurred in Costa Mesa and downtown San Diego as well as adjacent cities. The main storm system on December 6th brought widespread rain to the entire region. All mountains and the coast and valleys areas received 1-3 inches and some spots receiving over 4 of rainfall over higher terrain. The most significant mud and debris flows occurred at recent Holy burn scar areas, and many reports of flash flooding across the region. Another strong cold front brought widespread rain on Christmas Day though the impacts were minimal. Snow fell as low as 4000 feet with mountains receiving 1 to 4 inches of snow including the San Diego mountains. Burns Canyon in the high deserts of San Bernardino County had a wind gust to 70 mph. |
