Snow totaled as much as 2" in the Colorado River Valley with 3" to 8" in the Kingman, Arizona area. A foot fell in Arizona in Oatman as well as on Hualapai Mountain..
The southerly track of the storm placed Las Vegas on the northwest edge of the storm with flurries falling over the south end of the valley.
This snow was also unusual in that high winds, gusting up to 35 mph, accompanied the snow resulting in blowing and drifting snow.
The snow also knocked out power resulting in pipes bursting as a result of the lack of heat in buildings.

 High tide in San Diego was 7.8 feet. 
In Eureka the tide was 9.1 feet, thought to be the highest in a century.

Two boys were rescued from the Santa Ana River in Colton. 
Numerous roads were washed out in the high desert and the mountains.

This day ended the wettest year ever recorded in Las Vegas and the only year in which more than 10" of rain fell.
A total of 10.72" of rain was recorded.

1940: Heavy rains that fell a week previous loosened soil along a Del Mar railroad and led to a landslide. 
The slide derailed a train and killed three.

1933: A major storm hit Southern California starting on 12.30 and ending on 1.1.1934. 
7.36" fell in 24 hours at LA, a 24 hour record for the city. 
8.26" fell as a storm total. 
Storm totals in the southern slopes of mountains topped 12" (heaviest: 16.29" in Azusa). 
45 died all over Southern California in floods. 
Walls of water and debris up to ten feet high were noted in some canyon areas.

Highways, water supplies and other utilities were damaged. 
A train from LA plunged into the Santa Ana River in Colton.

 Only 27 hours of sunshine were observed in Fresno during December 1900. 
This is just 9% of the total possible sunshine available for the month, making it not only the least sunniest December ever, but the least sunniest month ever here.
