Another wet winter in California . El Ninoi s back.
A warm, wet El Niño winter is in store for California and much of the U.S. LA Times.
The first winter outlook from the National Oceanic and Atmospheric Administration predicts that a strong El Niño will remain in place through at least the spring, with further strengthening possible over the next couple of months.
El Niño is the warm phase of the El Niño-La Niña Southern Oscillation pattern — sometimes referred to as ENSO — and is a major driver of temperature and precipitation patterns across the globe.
“The anticipated strong El Niño is the predominant climate factor driving the U.S. winter outlook this year,” said Jon Gottschalck, chief of the operational prediction branch at NOAA’s Climate Prediction Center.

>>> Remove the Snow from your Car Please… You can get a ticket for leaving snow on the roof of your car, it’s a hazard when it flies off. The heavy sierra cement snow can break out car windows behind you when it shed off. We saw CHP pulling people over and making them shovel it off on the side of the road the other day.
