THIS DAY IN WEATHER HISTORY:
2005: Five consecutive days of heavy rainfall started on 1/7 and ended on 1/11. The wet weather was blamed on an atmospheric phenomenon known as the “Pineapple Connection” or “Atmospheric River”. 31.75 inches fell in Lake Arrowhead, 29.70 inches at Lytle Creek, 19.86 inches in Devore, and 15.09 inches at Palomar Mountain. Four to ten inches fell at lower elevations. Flash flooding and mudslides caused millions of dollars of damage to homes, businesses, vehicles, parks, crops, roads and bridges. A state of emergency was declared in Riverside, Orange, San Bernardino, and San Diego Counties. Widespread catastrophic floods impacted nearly every community. This followed heavy storms in late December and earlier in January.

2001: A strong winter storm that started on this day and ended 1/11 brought two to four inches of rain to the coast and the valleys and 1.74 inches of precipitation to Phelan. Flash flooding occurred in Seal Beach, Huntington Beach, Garden Grove and Costa Mesa. 13 to 18 inches of snow fell in the Idyllwild area and three inches of snow blanketed Phelan. On this day a funnel cloud was observed at Orange County Airport. Wind gusts reached 71 mph at Phelan.
1998: Heavy rain that started on 1/8 and ended on this day brought two inches of rainfall, causing floods and mud slides in Del Dios (near Escondido).

1995: Heavy rain that started on this day and ended on 1/11. The result was widespread flooding of area creeks and drainage canals. The communities of Laguna Beach and Sun City were especially hard hit, with flood damages exceeding $55 million. An additional $6.5 million in damages occurred in San Diego County. President Clinton issued a Federal Disaster Declaration for the Region.
1993: A very wet series of storms that began on 1/6 and ended on 1/19 produced 20 to 50 inches of precipitation in the mountains and up to 12 inches at lower elevations over a two week period. It was one of the longest periods of consecutive days of rain on record (14) and measurable rain fell nearly every day from 1/2 to 1/19. Flooding and flash flooding, mud slides, etc., resulted.

1978: Ramona was drenched with 5.33 inches of rain, the all-time daily record rainfall for the town.

1953: San Diego Lindbergh Field recorded a temperature of 88°, the highest temperature on record for January.

A trace fell in San Diego, the only time since 1882. Three feet piled up at Mt. Laguna, and 18 inches fell on Cuyamaca, one foot in Julian, four to eight inches fell as low as 1000 feet in elevation. 43 inches of snow fell at Palomar Mountain from this day to 1/13, the greatest snowfall on record. A light covering was reported in La Jolla, Point Loma, Miramar, Escondido, Spring Valley, and other outlying San Diego areas. The snow snarled all kinds of transportation and caused power outages and emergencies. A plane crash killed five and injured one near Julian. A camping group was stranded at Cuyamaca. Wind gusts reached 75 mph in the mountains of San Diego County, with a gust to 40 mph in San Diego. In Idyllwild the high temperature was 23°, the lowest high temperature on record.

1946: Strong downdraft winds and reduced visibility from fog and rain was observed at the 5,000 foot level in the mountains east of Los Angeles. A DC-3 airliner crashed. 24 were killed in what was then the nation’s worst airline disaster in history. But this death toll would be surpassed only 14 months later east of San Diego.

1918: Strong offshore winds arrived at the coast. Peak wind at San Diego was north at 31 mph at 6:38 am. Skies were full of dust with 300 yards visibility. At noon visibility was only a few miles in the dust.

1907: A warm rain fell on snow in the San Bernardino Mountains, causing a flood around San Bernardino. At Big Bear Lake four feet of snow remained and then froze again. Trees were loaded with ice, snapping in the wind. Large Oaks and Cedars were downed. Telephone lines broke at every span.
