Precipitation Enhancement Program
For the past 20 years the EAA has taken a proactive approach to making rain clouds more productive by partnering with the Evergreen Underground Water Conservation District (UWCD) to perform cloud seeding operations. This initiative at our agency is known as the Precipitation Enhancement Program. The actual cloud seeding is performed by the South Texas Weather Modification Association (STWMA), which is a non-profit organization committed to enhancing rainfall across the South Texas region. STWMA is one of five permitted weather modification projects for rain enhancement in the state of Texas!
On this episode hosts Ann-Margaret and Brent are joined by Bria Hieatt, State Licensed Program Meteorologist for the STWMA, where she explains the process of cloud seeding and how it’s performed over Bandera, Medina, Uvalde counties and the outskirts of Bexar County for the EAA’s Precipitation Enhancement Program.
