Cloud seeding tried in California in an attempt to make rain

Clouds over Los Angeles County were seeded with silver iodide to increase the amount of rainfall during Monday's storm, marking the first cloud seeding done by the Department of Public Works since 2002.

Los Angeles County has used cloud seeding to boost water supplies since the 1950s, backing off in times of heavy rain or when wildfire devastation creates an outsized risk of flooding or debris flows.
