Rain Enhancement Technologies Reports More Than 20% Warm-Season Precipitation Enhancement at La Sal Mountains Deployment
Key Highlights
- ➤Warm-season precipitation enhancement exceeded 20% at La Sal Upper station
- ➤April-July precipitation totaled 9.90 inches, with more than 2 inches attributed to enhancement
- ➤Positive-effect probability reached 97% under ridge regression and 82% under BSTS
- ➤Winter and warm-season results indicate WETA effects extend beyond snow season
- ➤WETA operations were suspended during August-September National Weather Service flood warnings
Expert Statements
Randy Seidl, CEO of Rain Enhancement Technologies
“Our winter results showed what the WETA can do for snowpack. These warm-season findings matter because they show the same installation continuing to deliver during the months when farmers, ranchers and water managers feel water stress most directly.”
Randy Seidl, CEO of Rain Enhancement Technologies
“We are reporting these as preliminary results, and we are deliberately conservative in how we present them. We would rather let the data build the case season by season than overstate what a single season can tell us.”
Dr. Jeffrey Chagnon, Senior Meteorologist at Rain Enhancement Technologies
“The question we set out to answer is simple: how much precipitation would La Sal have received without the WETA?”
Dr. Jeffrey Chagnon, Senior Meteorologist at Rain Enhancement Technologies
“By building that estimate from control sites that see the same storms, and testing it with two very different statistical approaches, we can separate the array's effect from the natural ups and downs of the weather. Both models point in the same direction for the April through July period, which gives us confidence in the seasonal result.”
NAPLES, FL / ACCESS Newswire / October 22, 2026 / Rain Enhancement Technologies Holdco, Inc. (NASDAQ:RAIN) ("RET" or the "Company"), a leading provider of ionization precipitation enhancement technology, today announced preliminary warm-season results from its deployment of the WETA (Weather Enhancement Technology Array) in Utah's La Sal Mountains. The Company's analysis of April through July 2026 precipitation at the La Sal Upper monitoring station estimates more than 20% enhancement compared with what the site would have been expected to receive without the WETA. Both statistical models used in the evaluation place the probability that the WETA had a positive effect above 80%.
The results follow RET's previously reported winter 2025-26 findings, in which the Company's analysis estimated more than 20% enhancement in snow water equivalent at the same site during a historically dry winter. Together, the two periods indicate that the WETA's effect extends beyond snow season into the spring and summer months, when water demand from agriculture, communities and ecosystems typically peaks.
