Tremendous Rain and Snow in California

It was just over a week ago when I mentioned that the developing pattern in California could produce in excess of 20 inches of rain and over 10 feet of snow to parts of California (Storms to Blast California), so let’s take a look at precipitation across the state for the last seven days.

Rain or Liquid Equivalent

Data from NOAA Precipitation Analysis Web site shows the amount of rain and rainfall equivalent for the areas where the precipitation was snow for the week ending at 7 a.m. P.S.T.

Many areas had in excess of eight inches, with quite a few locations in the mountains in the north, the coastal range, and the mountains to the east of Los Angeles having received between 10 and 15 inches. There seems to be a spot to the north of Redding (northern mountains) that reported 20 inches of rain.

I haven’t had time to research the amount of snow that’s fallen in the mountains, but Mammoth Mountain is reporting 92 inches of snow in the last 7 days, which is a nice, round 8 feet of snow. It’s certainly impressive.

The belief that the weather is always boring in California (and always easy to forecast) is widespread, which is something I wrote about in Weather Whys. This is why it’s not!
