I had DirecTV for several years and never noticed any problm with wind. Heavy rain (very heavy) on the other hand, would cut out service. In Northern Virginia, that seemed to happen maybe once every coupld of months, although I didn't watch that much TV so there were probably other times I didn't notice. It wasn't a big deal, though.
Interesting. My neighbor reported that her satellite connection (I should have asked her what service she uses) was up and running long after my cable service kicked out.
