Utah and several western states are grappling with severe snow droughts, raising urgent concerns about escalating wildfires and declining water levels in the critical Colorado River. A pioneering startup claims that by releasing negatively charged aerosols into clouds, it has managed to boost snowfall by 20% across some Utah mountain ranges.

Rain Enhancement Technologies conducted a comparative study of snowfall between the La Sal Mountains and the Abajo Mountains, located 70 kilometers to the south, during five recent dry winters. In January, while operating a high-voltage ionization array upwind of the La Sal Mountains, the company noted an unexpected nine centimeters more snow than anticipated based on the snowfall data from the Abajo Mountains.

However, scientists urge caution, indicating that these observed results might be coincidental and that it is premature to assess the technology’s overall effectiveness.

“While cloud seeding methods have been implemented for years, our approach offers an alternative to enhance precipitation without the need for chemicals,” explains the company’s meteorologist, Jeff Chagnon. “You can activate it from anywhere in the world without needing to fly into the clouds, typically running it for about 48 hours.”

The United Nations has signaled that the world is approaching an era of “water bankruptcy,” with three out of four individuals potentially facing water scarcity or pollution issues. In contrast, countries like Iran, grappling with severe water shortages that have incited protests, are attempting to induce rainfall by dispersing salts like silver iodide from aircraft. Currently, nine U.S. states are known to conduct cloud seeding programs.

Nonetheless, public apprehension about potential health risks linked to the substantial amounts of silver iodide released, along with conspiracy theories surrounding “chemtrails,” contribute to a growing distrust of climate modification initiatives. In fact, cloud seeding is either banned or under scrutiny for potential bans in ten U.S. states.

Rain Enhancement Technologies employs a system that passes 10,000 volts of electricity through coiled wires suspended between two 8-meter pylons. Tiny aerosols, such as dust, soot, and salt, acquire electrons as they pass near these wires, similar to how static electricity builds up on your body when you walk on a carpet. Wind subsequently carries these ionized particles into the clouds.

In the clouds, water naturally condenses around aerosols, forming droplets that can collide and coalesce. When they stick together, they fall as rainfall. However, many smaller droplets typically remain suspended due to upward air currents.

Charged droplets can interact even when they possess the same charge. The negative side of one droplet attracts the positive side of another, creating an electric polarity that enhances collision rates. When droplets coalesce around the negatively charged aerosols from Rain Enhancement Technologies, their increased interactions lead to enhanced rainfall, Chagnon explained.

Although this technique cannot create clouds or induce upward air movement, “we can effectively extract additional water from existing clouds,” notes Chagnon.

Evidence from the Cold War indicates that electrical charges can enlarge cloud droplets. A 2020 study revealed a 24% increase in precipitation day over day in the Shetland Islands, UK, attributable to ionized air resulting from a nuclear bomb test. When radioactive ionization occurred, cloud dynamics were altered.

Trials conducted by Rain Enhancement Technologies in Oman from 2013 to 2018 reported precipitation increases of 10-14%. Additionally, an experiment in China that employed negative ion dispersion showed a 20% increase in precipitation.

Nevertheless, the World Meteorological Organization cautions that while salt diffusion in winter clouds has been documented to influence precipitation, the ionization method still lacks robust scientific validation.

“It’s fascinating that their findings align with observable changes in cloud behavior,” remarks Edward Grispeed from Imperial College London. “However, factors influencing precipitation, including snowfall and rainfall, are highly variable; thus, the chances of their results being coincidental cannot be dismissed.”

Rain Enhancement Technologies acknowledges that the five dry winters used as a baseline for assessment may not adequately represent the natural variability in snowfall from season to season, says Jeff French from the University of Wyoming.

“I recommend awaiting further experimental investigations and more extended data to confirm the viability of ionization as a snowfall catalyst,” adds Ibrahim Oloud from Mutah University in Jordan.

Western US Sees Record Low Snowfall: What This Means for Winter Weather Trends

Last weekend’s winter storm may have covered much of the country with significant snow and ice, but winter has yet to fully arrive in the Western United States. Several states are grappling with snow-induced drought.

According to Peter Goble, the assistant state climatologist, Colorado is experiencing its lowest snowfall amounts on record for this time of year. “All of our mountain ranges are well below normal,” he reported.

Utah is facing a similar predicament.

“We’re in uncharted territory right now, heading toward our lowest snowfall ever by February 1,” stated Kevin Perry, an atmospheric scientist at the University of Utah.

Scientists are increasingly alarmed about the implications for water supplies and wildfire risks later this year. Mountain snowpack in Western states serves as a crucial water source in spring and summer, directly impacting agricultural irrigation, wildfire dangers, and hydroelectric power generation.

Western snowpack data is sourced from the National Resource Conservation Service, which monitors more than 800 high-elevation monitoring stations across several mountain basins. Their measurements show that nearly all basins in the continental U.S. West are trending below average.

While it’s not uncommon for some basins to fall below historical averages, it’s rare for nearly all Western regions to be facing snowfall deficits.

In Washington state, a recent climb to Mount St. Helens in mid-January revealed conditions resembling June rather than mid-winter, exposing large areas of volcanic rock near the crater’s rim.

The causes of the snow drought differ by region; however, unusually warm winter temperatures have resulted in more precipitation falling as rain rather than snow. Such was the case during a December atmospheric river storm in the Pacific Northwest.

“Washington, Oregon, California, and many Western states recorded their warmest December on record, leading to torrential rains and flooding not limited to mountainous areas,” mentioned Philip Mort, a professor at Oregon State University’s College of Earth, Ocean, and Atmospheric Sciences.

Currently, moisture flow has significantly diminished in the northwest.

In Utah, early seasonal rains during November and December melted lower-elevation snow, leaving the Wasatch Mountains looking heavily peak-laden, Perry noted.

“The high-elevation snowpack is relatively good,” said Perry, “but there’s a significant lack of low and mid-elevation snow.”

Colorado continues to experience hot and dry conditions.

“December 2025 was 9 degrees warmer than the statewide average and the warmest recorded since 1895,” Goble noted.

California’s snowpack, known for its boom-bust cycles, is looking better, especially in the southern Sierra Nevada, where several basins report above-average snowpack levels.

However, immediate relief for the remaining areas thirsting for snow is unlikely.

The National Oceanic and Atmospheric Administration’s Climate Prediction Center forecasts: Dry weather across much of the West for the next two weeks along with temperatures above average in the coming month.

Mort suggests that regions west of the Cascade Mountains might recover with a few significant storms later this winter or spring.

However, in most parts of eastern Washington and Idaho, “the story seems already written, making change unlikely,” he explains.

Scientists are grappling with measuring climate change impacts on snowpack, as rising temperatures alter precipitation patterns. Snowfall trends are also swayed by natural fluctuations. A 2024 study in *Nature* indicated that climate change is responsible for the snowpack decline across the Northern Hemisphere.

Mort’s data on the western United States indicates a dramatic decrease.

“The narrative becomes clearer and more somber,” he stated.

If low snow conditions persist, it will exacerbate already tense negotiations among seven Western states over the distribution of the Colorado River’s water, crucial for 40 million residents. River flows are diminishing due to prolonged drought and the fact that users are allowed to withdraw more water annually than is available.

Earlier this month, the Bureau of Reclamation released draft water management strategies supporting 5.5 million acres of agricultural and hydropower operations across California, Arizona, Nevada, Colorado, New Mexico, Utah, and Wyoming.

States are actively negotiating long-term strategies for managing the river’s water to prevent Lake Mead and Lake Powell dams from experiencing “dead pool” conditions that would halt downstream river flows. However, reports indicate that these negotiations have stalled.

“In the short term, a low snow year could heighten the urgency to finalize these agreements,” said Goble.

Large factory emissions may contribute to snowfall.

Satellite images show that plumes of pollutants from large factories can cause snowfall and leave holes in widespread clouds.

It has long been known that fine particles of soot-like pollutants, known as aerosol pollution, can affect clouds in a variety of ways. Water vapor can condense on pollutant particles and cause cloud formation, and pollutants can also change the properties of existing clouds.

While researching these effects, Vere Thor Researchers at the University of Tartu in Estonia noticed that holes sometimes appear in clouds downwind of major pollution sources. He and his colleagues have now analyzed thousands of satellite images of North America and Eurasia and found 67 locations where this effect can be seen under the right atmospheric conditions.

Weather radar confirmed that these events were causing snowfall. In the largest example the researchers found, up to 15 millimeters of snow fell over an area of ​​2,200 square kilometers (850 square miles).

This happens because pollutant particles freeze around supercooled water droplets in the cloud, creating ice crystals that grow into snowflakes, Toll said. “And as the water comes out of the clouds as snow, you end up with fewer clouds.”

In the absence of particles, water droplets in clouds remain liquid even when the air is as cold as -40°C (-40°F).

Most of the 67 sources of pollution found by the research team were oil refineries and factories producing metals, cement, and fertilizers. But surprisingly, the researchers occasionally observed similar effects near four nuclear power plants that do not produce any aerosol emissions.

This could be because the warm air rising from these power plants is picking up aerosol pollution from elsewhere, but the researchers have not confirmed this. “There's no clear explanation for that,” Toll said.

In theory, it's possible to intentionally induce snowfall using aerosol effects, but that would only work if a cloud of supercooled liquid water droplets was already present, Tolle said. say.
