| Episode narrativeepisode_narrative | A low pressure system from the East brought a surge of subtropical monsoon moisture into the region. These ingredients set off periods of showers and thunderstorms, with areas of flash flooding affecting the San Diego, Riverside and San Bernardino County mountains, as well as the high desert on the 21st and 22nd, including significant rainfall and flash flooding the morning of the 21st, resulting from a nocturnal MCS. Rainfall amounts varied widely, though some of the stronger storms produced very heavy rain of 2-3 inches at a time. This heavy rain combined with recent burn areas on the 21st to produce major debris flows, most notably at the Mountain Fire in Riverside County, near Idyllwild. Several locations within this burn area reported rock and debris flows across roadways, including Highway 74. One debris flow even tore through a pond, displacing the water and killing the fish. Portions of the Sunrise Highway and Interstate 8 in the San Diego County mountains and roadways in Ocotillo Wells were closed due to large amounts of flowing water, mud and rocks. The bulk of the storms on the 22nd affected the San Bernardino County mountains, especially the Big Bear area, where three homes were flooded. Another area of Big Bear was blanketed with up to 1.5 inches of accumulated hail, ranging from one-quarter to one-half inch in size, shredding some plants and flowers. The Anza Borrego State Park, in the San Diego County deserts, experienced the worst flash flooding on the 22nd. Dual-Pol radar reported estimates of 2 to 4 inches of rainfall within portions of the park. Several locations along Highway 78, through the park, had water, mud and rocks flowing over the road, the deepest of which was 12 inches deep and about 30 feet across. No one could pass through, stranding one car between this flow and another about 6 inches deep. The Fish Creek drainage within the park also experienced flash flooding, carrying away and destroying 3 unoccupied vehicles. |

The Shrine Camp area was recently burned during the Chariot Fire. The nearby Volcan Mountain Alert gauge reported 0.78 inches of rain in 10 minutes and 1.14 inches of rain over 20 minutes. |
