How cloud seeding works.

Arlen Huggins, an expert in cloud seeding from the Desert Research Institute in Nevada, presented information on cloud seeding at the Susan River Watershed meeting held Nov. 29 at the Susanville Indian Rancheria Resource Center. Huggins said warm storms are not good candidates for cloud seeding, and the most successful programs will only increase precipitation by 10 to 15 percent at the most — taking “a small sliver” of moisture and leaving most of the “water budget” of the storm to continue downwind.
