Squeezing the clouds: Aboard the small plane making it rain in drought-stricken Honduras

Victor Torres, a Mexican pilot with Startup Renaissance, operates a King Air C90 to seed clouds over Comayagua, Honduras. The operation uses 1,000 liters of silver iodide and additional air to stimulate precipitation, with Torres coordinating from the cockpit as a meteorologist on the ground provides target coordinates.

The mission involves spraying the tail of the aircraft and crossing back and forth over a selected cloud, aiming to enhance rainfall within a 13-minute window and then monitoring the emergence of thousands of droplets on the windows. The effort is planned to achieve a measurable increase in rain, with pilots noting a 40% to 60% predicted rise in precipitation under suitable atmospheric conditions.

Honduras is grappling with severe drought amid El Niño, with millions under various alerts and significant water restrictions in Tegucigalpa. The government contracted Startup Renaissance to conduct cloud-seeding flights, part of a broader set of measures such as groundwater drilling and seed distribution for farming communities.

Experts emphasize that cloud seeding can produce near-immediate rainfall only under specific environmental conditions and will not resolve a drought on its own, especially during strong El Niño. The World Meteorological Organization cautions about possible environmental side effects and stresses the need for rigorous project design and independent evaluation.

The initiative has drawn mixed reactions: supporters view it as a practical stopgap for water-scarce regions, while critics question its effectiveness and potential unintended consequences. Early reports from the operation note variable rainfall outcomes, and officials describe the effort as a partial, bandage-like measure within a broader strategy to cope with prolonged drought and water shortages.
