Utah’s winter sports industry may claim the greatest snow on Earth, but for skiers and water watchers alike, there is hardly ever enough powder.
For nearly 50 years, the second-driest state in the nation has been giving natural winter storms an engineered boost to help deepen its snowpack through a program largely funded by state taxpayers, local governments and water conservancy districts.
As cherry blossoms and calla lilies spring to life, the sun shines and rain showers begin to seem like a distant memory. Spring is here, and with it Santa Cruz County has begun to show early indications of drought, with little reprieve in sight.
As California’s seasons become warmer and drier, state officials are pondering whether the water rights permitting system needs revising to better reflect the reality of climate change’s effect on the timing and volume of the state’s water supply. A report for the State Water Resources Control Board recommends tailoring new water rights permits to California’s increasingly volatile hydrology. And it warns that the increasingly whiplash nature of California’s changing climate could require existing rights holders to curtail diversions more often and in more watersheds — or open opportunities to grab more water in climate-induced floods.
With three-quarters of the US west gripped by a seemingly ceaseless drought, several states are increasingly embracing a drastic intervention – the modification of the weather to spur more rainfall. The latest reports from the US Drought Monitor have provided sobering reading, with 40% of the US west of the continental divide classed as being in “exceptional drought”, the most severe of four levels of drought.
The mountaintops rumble to life unnaturally each year as snow clouds darken the sky across the West.
Open flames burst from the throats of metal chimneys, mounted on squat towers nestled among the peaks. With a low hiss, puffs of particles belch from their mouths into the air, where the wind catches them and whisks them away.
Another March storm moved through California on Monday, bringing snow to the Sierra Nevada, rain showers elsewhere and gale conditions offshore.
A mix of winter storm warnings and winter weather advisories stretched the length of the Sierra and southward into mountain ranges of Southern California that were just coated with snow last week.
Caltrans recommended motorists traveling through the Sierra check for chain requirements.
A late-winter storm doused the San Diego area with rain and mountain snow for second day Thursday, but a dry spell lies ahead.
Though the showers generated by the unsettled atmospheric system out of the Gulf of Alaska were more scattered and short-lived than Wednesday’s storms, they added to some significant moisture amounts across the county, according to the National Weather Service.
A cold, late-winter Pacific storm brought rain and snow to California on Tuesday. Winter storm warnings were posted or scheduled to take effect during the day in mountains from the Oregon border south to the U.S-Mexico border. Mountain travel was discouraged due to the potential for major delays, chain controls and near-whiteout conditions, the National Weather Service said. The San Francisco Bay Area weather office warned of possible hail, thunderstorms and downpours that could make driving risky.
As the planet warms, scientists expect that mountain snowpack should melt progressively earlier in the year. However, observations in the U.S. show that as temperatures have risen, snowpack melt is relatively unaffected in some regions while others can experience snowpack melt a month earlier in the year.
The winter storms that dumped heavy snow and rain across California early in 2021 are likely not enough to negate what will be a critically dry year, state water officials believe.
California’s Department of Water Resources on Tuesday recorded a snow depth of 56 inches and water content of 21 inches at Phillips Station in the Sierra Nevada. The water content of the overall snowpack was 61% of the average for March 2 and 54% of the average for April 1, when it is historically at its maximum.
