Florida - FLL takef-off corridor changes?

Hi

I live in west Boca Raton and planes fly over that area quite often. Before several weeks ago by the time planes reach us they would be above 10000ft and there was no noise at all. Now they are flying a lot lower than before and I can't match that to any weather/construction etc. Does any one know anything about that change?

Let's seek the help of the readers of the Travel->Florida forum. I'll move the thread there. Ocn Vw 1K, Moderator, TravelBuzz.
