| Episode narrativeepisode_narrative | A strong, cold upper-level low developed over the north Pacific, with a deep trough and strong, embedded jet extending all the way down to southern California. The main area of precipitation passed through the area the 17th through the 19th, providing widespread moderate to heavy precipitation over and west of the mountains. Areas west of the mountains generally received between one-half of an inch, and one inch of rain, through San Diego County came in somewhat higher, with some amounts near 2 inches along the coastal slopes. According to the Lytle Creek HADS gauge, approximately 3 inches of rain fell in the Lytle Creek drainage (mostly over a three-hour period), causing a 2 to 3 foot rise in the creek at a point where the bed was 25 feet wide. This rise in flow did not leave the creek banks. There were also several other instances of rocks and mud in roadways, but no major flooding occurrences. The San Bernardino County Mountains were the big snow winners with Arrowbear coming in at 28 inches, Big Bear with 12 inches and Wrightwood with 7 to 13 inches. The San Diego County Mountains were not far behind with Cuyamaca receiving 15+ inches, Julian with 12 inches, and Palomar Mountain with 10 inches. Snow drifts in the San Bernardino and San Diego Mountains were upwards of 2 to 3 feet in some areas. Most areas between 3000 and 7000 feet received between 4 and 10 inches, which when melted and combined with rain received up to 3 to 4 inches of liquid equivalent. One location, near the Lake Arrowhead COOP station reported around 5 inches of water equivalent. The snow level was particularly low with this event, bringing as much as 3 inches of snow down to around 2500 feet. Graupel was observed in Temecula, accumulating to around an inch at 1200 feet. The upper deserts received moderate amounts of rain ranging from less than one-quarter inch to over three-quarters of an inch at Phelan. Some snow fell near the desert mountain slopes as well, with Hesperia at around 1 inch. The lower deserts fared quite well, with one-tenth to one-quarter of an inch in the Coachella Valley and one-quarter to slightly over one inch in the San Diego County deserts.|Strong, gusty winds also accompanied this system. Numerous gusts over 60 mph resulted in power outages, blowing dust and traffic signs blown down. |
