THIS DAY IN WEATHER HISTORY:
2017: A strong mountain wave produced an impressive wind gust of 107 mph at Burns Canyon (east side of San Bernardino Mountains).

2009: Santa Ana winds gusted up to 83 mph at Fremont Canyon. Winds downed trees and power lines, overturned semi-trucks, and damaged roofs.

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 very high tide and a four foot surf flooded Surfside in Seal Beach.

1998: Heavy rain that started on 1/8 and ended on 1/10 brought two inches of rainfall, causing floods and mud slides in Del Dios (near Escondido). A tornado hit Long Beach causing property damage. A waterspout was observed three miles off Laguna Beach.

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.

1949: The most significant snowstorm to hit lower elevations started on this day and ended on 1/11. 14 inches fell in Woodland Hills, eight inches in La Cañada and Catalina Island (at 2,100 feet), six inches in Altadena, five inches in Burbank, four inches in Pasadena, one inch in Laguna Beach and Long Beach. A trace fell in San Diego, the only time since 1882. Three feet piled up at Mt. Laguna, 18 inches fell on Cuyamaca, and one foot in Julian. Four to eight inches fell as low as 1000 feet in elevation. 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.

1948: It was 82° in Idyllwild, the highest temperature on record for January.

1888: Freezing temperatures in inland valleys killed the citrus crop.
