We have the same here. They spray more heavily before storms and then it usually does not rain. Just a lot of wind and clouds.

The formula they spray before storms is different than the other usual formulas (I can tell because I'm very sensitive and can taste them... it's horrible).

I also believe it's depopulation and perhaps HAARP virtual wave guides used in earthquake creation. I would never have believed this without some research and discovering that it's all in their own literature.
