A Surge From an Atmospheric River Drove California’s Latest Climate Extremes

Flooding rains and record snow in California last week marked another extreme swing of the state’s climate pendulum. The widespread downpours triggered mudslides that damaged homes and roads near some of the huge fire scars from last summer, and also brought some of the water the state will need to end a months-long hot and dry streak and douse a record-setting wildfire season that extended into January.

Despite Rainfall, State Still Aiming for 55 Gallon Per Person Water Conservation Target

Fresh off a week filled with rain and snow due to an atmospheric river, water conservation may not be top of mind for everyday Californians.

NBC Bay Area Meteorologist Rob Mayeda just broke down some figures from this latest storm. In a Friday tweet he says, “Sierra Snowpack Surge: Up to 66% of average from just 40% one week ago. Biggest rains for the Central and Southern Sierra.”

While the recent precipitation may make the 2011-2017 California drought seem like a distant memory, a couple of laws passed by the legislature at that time are set to rain down policy on water agencies throughout the state.

Starting in November of 2023, California will enact a statewide indoor water use standard of 55 gallons per person per day. Local water agencies could be fined $10,000 a day by the state if they fail to meet the standard.

February 1: Is California Still Heading for a Multi-Year Drought?

This updates a post from December on the likelihood of California entering a second dry year. Normally, a second dry year brings drought operations for California’s overall water system operations.

Today, it is even likelier that California is entering a multi-year drought.

Precipitation conditions have improved somewhat with a nice atmospheric river this last week, but remain 51% of average for this time of year for the Sacramento Valley. (San Joaquin and Tulare basins are 61% and 47% of historical seasonal average precipitation so far.) Snowpack has improved somewhat with very recent storms, but is about as scarce as the precipitation.

Opinion: Water Markets in California Can Reduce the Costs of Drought

California’s increasingly volatile warming climate is making droughts more intense, and complicating water management. A just-launched commodity futures market for the state’s water provides a new tool for farmers, municipalities and other interested parties to ensure against water price shocks arising from drought-fueled shortages.

Taking a Wall Street approach to an essential natural resource has prompted both fear and hype. Will California experience a new Gold Rush in water? Will speculation boost the cost of water? Perhaps both the fear and the hype are unwarranted.

Climate Change Ravaged the West With Heat and Drought Last Year; Many Fear 2021 Will Be Worse

If there were any doubts that the climate is changing in the Colorado River Basin, 2020 went a long way toward dispelling them, thanks to yet another year of extreme weather.

Unprecedented wildfires, deadly heat waves, withering drought—the many indicators of the climate mayhem that scientists have been warning about for years—ravaged the landscape, claiming dozens of lives and causing billions of dollars in damage.

Colorado endured an unprecedented wildfire season. And so did California, in some cases burning where the wounds were still fresh from the epic fires of 2018. Utah experienced its driest year ever, and persistent high temperatures killed more people in Arizona than ever before. Monsoon rains that typically bring relief throughout the region were a no-show for the second summer in a row and now are being called the “non-soon.”

Tensions Rise Over Company’s Plan to Sell Colorado River Water in Arizona

Mayors and county supervisors in towns along the Colorado River were already upset five months ago when the state water agency endorsed an investment company’s plan to take water from farmland near the river and sell it to a growing Phoenix suburb.

Now, they’re incensed that the agency, which initially suggested holding back a large portion of the water, changed its stance and will let the company sell most of the water to the town of Queen Creek.

California Storm Winds Down After Deluge of Rain and Snow

A drenching storm that brought California much-needed rain in what had been a dry winter wound down Friday after washing out Highway 1 near Big Sur, burying the Sierra Nevada in snow and causing muddy flows from slopes burned bare by wildfires.

The atmospheric river weather system that barreled ashore in Northern California early in the week rolled quickly through Southern California overnight and was moving east before dawn. Remnants unleashed occasional downpours and hail.

What Are These Atmospheric Rivers that Bring Heavy Rain and Snow to California?

An atmospheric river — a plume of moisture that has been likened to a river in the sky — has brought heavy precipitation to the Central Coast. Now it will sag southward and bring rain and mountain snow to Southern California on Thursday night into Friday morning, the National Weather Service said.

What is an Atmospheric River? California has Long History of Intense Rain Storms, Floods

An intense cold front will tap into subtropical moisture and take on atmospheric river characteristics as it moves southeastward through the Central Coast on Wednesday into Thursday.

At this time, between 2 and 4 inches of rain is expected along the Central Coast. However, if the front stalls over a particular area, rainfall amounts will be much higher.

Shiver Me Timbers: High Winds Chill Out San Diegans

The second cold winter storm to arrive in the San Diego area over the past week brought more downpours, mountain snow and high winds to the region Monday. As of early Monday evening, the inclement conditions had delivered up to about three-fifths of an inch of precipitation along the coast and in the local deserts, a little more than an inch in the inland valleys, and almost 2 1/3 inches in parts of the East County highlands, according to the National Weather Service.
