Scientists Use New Methods to Better Forecast Atmospheric Rivers

/in , /by /Sierra Nevada Allyby Scott King

Earlier this year, the Center for Western Weather and Water Extremes launched a new sub-seasonal to seasonal forecast product to better predict the influence atmospheric rivers will have on the Western United States. Better and more accurate forecasting tools for atmospheric rivers are critical for a number of community uses, including water management, agriculture, insurance and commodities trading, to name a few.

The demand for better atmospheric forecasting tools has facilitated the development of the new S2S forecasting products launched by CW3E this year.

Waves Off Central Coast Contain Clues About Changing Climate. Is California Due for Drought?

/in , /by /San Luis Obispo Tribuneby John Lindsey

The waves along the Central Coast can tell you a lot about our changing climate, and here’s why.

The Diablo Canyon Power Plant’s Waverider Buoy has measured wave heights and periods since June 1983 and directions since June 1996 and is one of the longest continuous-wave monitoring stations along the West Coast.

Scripps Institute of Oceanography’s Coastal Data Information Program maintains an extensive network of buoys that monitor waves along the coastlines of the United States. You can view the historical wave data archive from Diablo Canyon and other stations at the CDIP database at cdip.ucsd.edu.

US: More Must Be Done to Protect Colorado River From Drought

/in , /by /AP News by Felicia Fonseca

A set of guidelines for managing the Colorado River helped several states through a dry spell, but it’s not enough to keep key reservoirs in the American West from plummeting amid persistent drought and climate change, according to a U.S. report released Friday.

Millions of people in seven states and Mexico rely on the river for drinking water and growing crops. The 2007 guidelines were meant to lessen the blow of any future cuts in the water supply for growing areas, giving states an idea of what to expect each year and ways to manage the risks.

Drought, Climate Change and Groundwater Sustainability — Western Water Year in Review

/in , /by /Water Education Foundation (Western Water)by Douglas E. Beeman

The ability of science to improve water management decisions and keep up with the accelerating pace of climate change. The impact to precious water resources from persistent drought in the Colorado River Basin. Building resilience and sustainability across California. And finding hope at the Salton Sea.

These were among the issues Western Water explored in 2020. In case you missed them, they are still worth taking a look at.

Colorado River Basin Winter Forecast Signals Dry Times Ahead

/in , /by /KUNCby Luke Runyon

All signs are pointing to a dry start to 2021 across much of the Colorado River watershed, which provides water to about 40 million people in the Western U.S.

A lack of precipitation from April to October made this spring, summer and fall one of the region’s driest six-month periods on record. And with a dry start to winter, river forecasters feel more pessimistic about the chances for a drought recovery in the early part of 2021.

Drought Keeps Lake Mead Levels Low, But There is Plenty of Winter Left

Last week’s storm did little to ease the drought in Arizona’s reservoirs. But there’s still plenty of winter left.

The Bureau of Reclamation makes two-year projections, based on weather and water levels in Colorado River reservoirs, and its most recent projections have been dire.

That could set the stage for an Arizona water shortage in 2022. Snowpack in the mountains is now 69% of normal, but Patti Aaron, a spokeswoman for the bureau, says a little snow could go a long way.

Santa might be able to lose the heavy red coat when he makes his rounds in the Southland, and he probably won’t need an umbrella either.

The extended outlook from the National Oceanic and Atmospheric Administration favors above-average temperatures and below-average precipitation in the Los Angeles region from Dec. 24 through Dec. 30.

It’s possible that San Diego County won’t receive significant rainfall during December, which would significantly elevate the wildfire danger throughout the region, according to the National Weather Service.

“The storms that have been forming off the Pacific Northwest are not dropping into Southern California,” said Dan Gregorio, a weather service forecaster.

From Droughts to Flooding, Here’s How California is Trying to Better Understand Atmospheric Rivers

/in , /by /ABC10 KXTV Sacramentoby Monica Woods

California weather is rarely average. Historically, the state has well above or well below average rain and snow. One of the keys to prepare for these wild swings is a better understanding of atmospheric rivers. The Center for Western Weather and Water Extremes or CW3E is at the heart of this research.
