Neighboring Sonora is again turning to cloud seeding to try to address the impacts of a historic drought.
Later this month, planes will begin dropping silver iodide again on the state, which has been experiencing historic drought in recent years.
Over the summer, 17 flights delivered roughly 1,500 liters of the material, and officials claimed the effort was successful in promoting rainfall, though other places in the region also experienced above-average monsoon seasons without such interventions.
Before this year’s monsoon season, nearly the entire state was experiencing extreme or exceptional drought. Now nearly 80% of the state shows either no drought, or only atypical dryness, according to the most recent federal data. The state’s reservoirs, critical for drinking water and agricultural production, have also rebounded significantly.
