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.
ANY rain will help....
its like here in the NW...the weather people lament if we don't get enough snow pak in the winter or enough rain in the spring because of the fire danger in the summer, but they'll also lament if we get TOO much snow and too much rain because it causes undergrowth to expand and then of course THAT is a fire danger in the summer..
yes
“The dinosaur media”
Needs to go the way of the dinosaurs
That is so true!
Joe Sonafabitchi disagrees.
And here's another Sargeant from 60's TV.
This El Niño is HUGE! Video

And Sgt. O’Rourke (Forrest Tucker) of ‘F-Troop’.
I disagree—From mission times we have had a 12 year cycle of heavy rains—the 12 year cycle ends next year—we will get too much water—people will die. Some may start to build an ark. Get ready for it! Batteries! (power will go out) have food and water ready-—canned food. lanterns, a battery or crank radio. Make copies of your documents and put them on a flash drive. It will start in November! There will be rain at Christmas but the worst will be in January-February-March 2016. I hope I am wrong—but rain is on the way.
Only the government can end the drought.
Yup, great TV back then.
Drink!
And no one has a plan to capture this forecasted bonanza of water expected this winter.
So rain isn’t gonna solve the drought?
Hmmm. I just doesn’t sound right.
I would start building more reservoirs to capture lots of rain but to a democrat that does not sound right either.
Prosit!
Raining here again. Glad I mowed today.
Stupid proclamation from’tje same liberal politicians who say “we can’t drill,our way out of our oil shortage.”
True - the water has to flow into places where California Democrats can't find it and release it to the ocean, first. :)
