| Episode narrativeepisode_narrative | A weak, upper-level trough moved through California overnight on February 26th, into the morning of the 27th, increasing gusty west winds and bringing a round of light to moderate showers over and west of the mountains. A much stronger, Pacific low pressure system took aim at southern California late on the 27th, bringing periods of heavy rain and high-elevation mountain snow through the 28th (with additional heavy rain through March 1). Most of the upslope rain and convective showers occurred on the 28th. Strong, long-duration upslope flow enhanced rainfall on southwest-facing coastal slopes. The four-day, storm total precipitation amounts were significant. Costal locations ranged from 1 to 3 inches of rain, with the valleys recording up to 4.5 inches toward the coastal slopes. Mountain locations varied widely depending on slope aspect, but most recorded between 3 and 8 inches of rain. The upper deserts recorded between one-tenth and one-half inch, while the lower deserts measured generally less than one-tenth of an inch. The notable exceptions were Palm Springs, Desert Hot Springs in the Coachella Valley and San Felipe in San Diego County, all of which measured between one-half of an inch and one inch. The big rainfall winners were along the southern slopes of the San Bernardino County mountains, with Yucaipa Ridge coming in at 11.11 inches, Lytle Creek with 9.67 inches and Cedar Glen with 9.10 inches. The snow level remained fairly high, around 6000 feet. Most locations saw between 2 and 7 inches of snow, with Big Bear Lake and Onyx Peak recording 9 to 10 inches. The significant rainfall in a relatively short period of time resulted in numerous instances of urban and flash flooding with mud/debris flows, causing numerous road closures and swift water rescues in and around the urban areas of Orange, (Anaheim), San Diego (Escondido and Fashion Valley), and Riverside (Fallbrook to Lake Elsinore) counties. The most significant of these was the mud slides and subsequent road closure of Highway 74 (Ortega Highway) stemming from the Falls Fire burn scar. Many road closures also occurred in the Coachella Valley as a result of heavy rainfall over the headwaters of the Whitewater River, flowing down the valley through the storm channel. Area rivers saw rises of 2 to 5 feet, in some instances within 12 hours. A 10 to 15-foot-tall and eight-foot-wide section of the quarter-mile levee protecting Buckwheat Road from Sheep Creek failed, threatening 8 homes with flood waters. Westerly winds with this system were significant as well, topping numerous large trees and power poles, as well as damage at John Wayne Airport. A report of a 102 mph wind gust came from the Bear Mountain ski resort weather equipment on the 28th. Conditions support this gust, however, no damage was reported. Thunderstorms on the 28th also produced gusty winds, downing several trees and damaging power lines and other structures. |
| Event narrativeevent_narrative | CHP closed Highway 18 from Snow Valley to Big Bear due to minor flooding and rock debris. A spotter reported a heavy debris flow along Highway 18 near the Arrowbear area. Arrowbear music camp will be blocked off. Another spotter reported 5 inches of water running down the street in his North San Bernardino neighborhood. The Press Enterprise in Riverside reported streets and parking lots flooded in the Redlands area. |
