4"-12" of rain fell in the coastal and valley areas over six days, 12"-28" in the mountains, up to 9" in the high desert and less than 4" in the lower desert.
Major landslides and flash flooding impacted the communities of Laguna Beach, Apple Valley, along the Whitewater Channel in the Coachella Valley near Palm Springs, Highland, Corona, Loma Linda, La Jolla, and the city of San Diego from 12/21 to 12/22.
Qualcomm Stadium was flooded, but was miraculously drained and prepared for the Poinsettia Bowl held there on 12/23.
Heavy wet snow accumulated above 6500 feet with amounts over 6" and as much as 2 feet above 7500 feet.
2010: This date was the start of a series of storms bringing record amounts of rainfall to much of the Hanford Warning/Forecast Area; this series lasted until the morning of the 23rd.
Kern County started receiving most of their heavy rain on the following day.
2008: A strong low pressure system moved slowly through Southern California, producing very heavy snow.
A snowstorm of a magnitude that hasn't occurred since 1979 descended on the mountains and high deserts from 12.15 to 12.18.
About a foot of snow fell in the higher elevations of Joshua Tree NP.
Snow was also reported in many lower desert areas.
Some roads were either closed or traffic was restricted.

Several roads were flooded and washed out in the northern Inland Empire, exacerbated by the extensive burn areas from earlier in the fall.
Snowfall amounts were 32" in Idyllwild, 28" in Big Bear Lake, 26" in Palomar Mountain, and 24" in Lake Arrowhead.
1967: A period of snow began on 12.13 and ended on 12.19.
The entire period of snow brought 50" to Mt. Laguna, 38" in Idyllwild, two feet to Palomar Mountain, and 12"-18" to the higher elevations.
One freezing death resulted, numerous schools and highways were closed, transportation was disrupted and there were power outages.
1961: Very strong winds overturned trailers, blew down trees, and damaged signs in the Reno, NV area.
