From the Ask Joe file, we have a follow-up to a question we addressed last week about the landslide in Washington.
Sandra asked if there is any chance that cloud seeding may have impacted or added to the landslide in Washington state?
Last week, we mentioned that cloud seeding operations are very localized. When they seed clouds in the Sierra to boost the snowpack, for example. The range is usually just a few miles, and maybe up to 40 miles, in some cases, from where the clouds are seeded to where the snow or rain ends up falling.
Joe also found there is no cloud seeding in Washington and Oregon, since they get plenty of precipitation there.
The closest cloud seeding operation to where the landslide happened is in Idaho. Idaho Power does conduct cloud seeding in and around Boise, but that's about 500 miles away.
So there is little chance any cloud seeding could have had an impact on the landslide area in Washington state.
Also, one other point, whether it is here in the Tahoe area or up in Idaho, the experts pay close attention to the weather reports and moisture levels to make sure their cloud seeding operations do not lead to flooding or other problems.
