TEXAS WEATHER MODIFICATION ASSOCIATION
The state’s newest program is that of the Trans Pecos Weather Modification Association (TPWMA), which began seeding for the first time in the spring of 2003
in a 4-county area along and west of the Pecos River. The TPWMA procured its own equipment, including two aircraft and a radar, and hired its own personnel
to run its operation, which covers 5.1 million acres in the region between El Paso and Midland.
