These clouds looked pretty stormy to me on an afternoon last week. Now I have to wonder if they were a result of the work of the LA County Dept. of Public Works. According to an article I read today, contract workers have been attempting to make it rain through "cloud seeding"—sending special flares containing silver iodide into the clouds to increase precipitation. The flares are shot from the foothills of the San Gabriel mountains.
Interestingly, even though cloud seeding has gone on in LA for 50 years, there didn't seem to be solid evidence that it was really effective. Sadly, the predicted El Nino rains have not appeared this year, so the drought remains concerning for LA.
