California Might Get Hit by a Rainstorm. It All Depends on These Two Weather Patterns

From record-breaking heat waves to historic rainstorms, September was nothing short of a meteorological roller-coaster ride and the Bay Area was given a front-row seat.

This roller coaster of temperatures and intense back-and-forth between extreme heat and strong rains has come to a halt, though. A quiet, mostly dry pattern looks to be taking center stage for October as California is set to enter its third consecutive year of La Niña. But another weather pattern could shake up our chances of seeing at least one more storm roll into California before the end of the month.

La Niña: What it Means for California’s Drought and the Upcoming Winter Rainy Season

The day before the state’s “water year” ended, Silicon Valley leaders gathered on Google’s campus in Mountain View and urged residents to continue conserving water as California’s drought drags on.

“It’s the third straight year of a bad and worsening drought,” said Wade Crowfoot, secretary of the California Natural Resources Agency, on Thursday. “Our scientists and climatologists predict that as we move into the winter, we can expect another, fourth dry year.”

Bleak Water Year Ending, With Hope for Future Elusive

Nearing the end of the water year on Sept. 30, California farmers and water officials are eager to turn the page to begin the next opportunity for the state to accrue snowpack and precipitation.

However, with a La Niña atmospheric phenomenon in the Pacific Ocean, which generally signals drier, warmer conditions, water officials say they are preparing for a fourth dry year next year.

California Is Expected to Enter a Fourth Straight Year of Drought

California is most likely heading into a fourth consecutive year of drought.

The state’s water year ends tomorrow, which has prompted predictions about what’s in store for the next 12 months. (California’s water year runs from Oct. 1 to Sept. 30, so that the winter rainy season falls within a single water year.)

Four in a Row: California Drought Likely to Continue

As California’s 2022 water year ends this week, the parched state is bracing for another dry year — its fourth in a row.

So far, in California’s recorded history, six previous droughts have lasted four or more years,  two of them in the past 35 years.

Despite some rain in September, weather watchers expect a hot and dry fall, and warn that this winter could bring warm temperatures and below-average precipitation.

Why Our Drought Isn’t Going Anywhere This Winter

The latest measurements from the National Oceanic and Atmospheric Administration shows the American West is in for another dry La Niña winter, unwelcome news for the West currently struggling to keep flowing its main source of water: the shrinking Colorado River.

“That’s the worry in the present situation is that the odds now are now with La Niña are tilted against a really wet winter, at least in the southern half of California which of course has already been really dry,” said Dan Cayan, a research meteorologist at the Scripps Institution of Oceanography.

North County Water Agencies Offers Low‐Cost Rain Barrels to Help Customers Save Water

To encourage water conservation as drought conditions persist, Carlsbad Municipal Water DistrictOlivenhain Municipal Water DistrictSan Dieguito Water District, and Santa Fe Irrigation District have partnered to offer discounted rain barrels to area residents this fall. Collecting rainwater for future use not only can save drinking water and money, but also reduces irrigation runoff that can carry pollutants into local waterways and beaches.

A Rare Third Year of La Niña is on Deck for California, Forecasters Say

Californians should brace for another year of La Niña as the stubborn climate pattern in the tropical Pacific is expected to persist for a third consecutive year, forecasters say.

The latest outlook, published Thursday by the National Weather Service’s Climate Prediction Center, has increased the chances of La Niña sticking around through November to 91%, a near certainty. The pattern may also linger into winter, with an 80% chance of La Niña from November to January and a 54% chance from January to March.

What La Niña Means for Fall in California

We’ve been stuck with La Niña for a long time – and, according to the latest National Weather Service outlook, we’re not getting rid of her just yet. There’s an 80% probability La Niña conditions persist between September and November, which will have an impact on fall weather in California.

La Niña usually splits California into two halves: bringing wetter conditions to the northern part of the state and drier conditions to the south.

Will a Rare ‘Triple Dip’ La Niña Yield Another Dry Winter?

Although we’re currently mired in the dog days of summer, it’s time to look ahead to the rainy season.

The state thirsts for a wet winter, with extreme drought existing in just under 60% of California. Below-average rain and snow have plagued the state the last couple of years, coinciding with La Niña conditions and expanding drought conditions.
