Some weather experts are predicting heavy rainfall this year in California, thanks to an El Niño that many hope will put an end to the historic drought.
This is the Godzilla EL Niño if it matures and comes to fruition, Bill Patzert, a climatologist with NASAs Jet Propulsion Lab, told NBC News last week.
A recent statement released by Californias state climatologist Michael Anderson sings a different tune.
California cannot count on potential El Niño conditions to halt or reverse drought conditions, he wrote. Historical weather data shows us that at best, there is a 50/50 chance of having a wetter winter.
So just how likely is it that this years El Niño will put an end to the drought? Not very likely, experts told NBC Bay Area.
To start, storm prediction is tricky business. Weather forecasting models typically run about two weeks out, but winterand the impact of El Niñois still several months away.
As a result, its difficult to make an accurate prediction, said Jeanine Jones, Interstate Resources Manager at the California Department of Water Resources.
A look at data from past El Niño winters wont help much either, says Jay Lund of the University of California, Davis Center for Watershed Sciences. He says that data for Northern California shows very little correlation between El Niño and heavy rainfall.
Youll see that there are some very low and very high El Niño events that have a lot of precipitation and very little precipitation, he added, referencing the graph below, which measures El Niño strength and corresponding streamflow.
Theres no evidence of a pattern there, Lund says.
In other words, El Niño could mean a lot of rain, or no rain at all in Northern California.
Southern California sees a greater correlation between the weather pattern and rainfall thanks to geographic proximity to El Niño.
The strongest correlation geographically is up at the Pacific Northwest, and down into Southern California and into the Mexico coast, said Jeanine Jones. Where we are in Northern California is in sort of a gray zone that can go either way.
That gray zone is exacerbated by a ridge of high pressure, called the Ridiculously Resilient Ridge, which buffers the Bay Area from stormy weather.
If we have a strong high pressure ridge off the coast, we dont get storms, Jones said.
But even if the ridge doesnt block El Niño, and fierce rainfall does arrive this winter, it still isnt likely to end Californias drought.
For some of the reservoirs, a half decent flood will fill them up pretty well, said UC Davis Jay Lund. Some of the larger reservoirs, itll take more than that.
It could take decades or even a century to fill up some of those aquifers, Lund added.
While heavy rains would certainly help quench Californias thirst, the claim that a wet winter is a 50/50 proposition is true.
Once they have the control they'll never let it go.
The same old story from “da weather experts”. They can’t get the next day’s weather right and we’re supposed to listen to them.
Joe Bastardi makes the csse thst this el will not be as influential as 1998.
They keep mentioning rain, but it snow in the Sierra that really fills California’s reservoirs.
and yet the promised...De Salinization Plants...are no where to be seen...
perhaps governor moonbeam can channel some rain for us....
oommmmmmmm
Yea, but it will take a year and you know weather predictors, they’re wrong more often than not and predicting El Niño is not like predicting a monsoon.
California could get a drenching of such biblical proportions that the topsoil of the entire state could slide into the Pacific, and the California Government would still be warning everyone that “recent weather conditions have in no way lessened the severity of our current drought.”
Who can we invade? No blood for water!
Will another year of drought force the loons under the dome to finally approve more dams?
If it does I’m willing to suffer through another year or 2 of drought. The lefty loons need to feel the pain of killing all prospective dams since the early 70’s.
Ever since the 1970’s, when the rains came after a long drought, the “experts” always said that the rain wouldn’t alleviate the drought. This sort of talk only stopped when flooding began.
Yeah. Rain runs off and really doesn’t help all that much. Snow is always the answer
Basically, the precipitation forecast models indicate the rain will be limited to southern ca. Northern ca will see normal to below normal rain due to a high pressure system forecast to remain in place in the pacific northwest. considering that for example Folsom Lake is at 25% capacity, even a normal year precip isn’t looking good.
Why stop then? They should stick to their guns!
Well California get’s a fair bit of its electrical power....from coal power plants....in .....Colorado..
How About .....we hijack the Colorado River???
well golly take a look at this map from back....in 2006.
I KNOW theres no De Salinization Plant over in San Rafael yet ........as Im less than five miles form there

Exactly right. If it doesn’t rain enough, it’ll be too much. They want working Americans on half-rations from here on. This administration is bound and determined to take this country back to 1966in the Soviet Union.
Ahh, Sargent Garcia, loved Zorro as a kid in the ‘50s.
