Hi.
If I where in a gondol high above ground I would rather want to get down quickly BEFORE the wind picks up. And also have a look at the weather forecast.
How about adding a grid of wind sensors in surounding area that can meassure if there is a great chance that a wind cast is imminent?
Having a second function that operate nearly independent on the main function, you should let it have its own address space. Just draw up the blink function as if it was the only function, but use some of the existing functions to activate or deactivate it (just by adding a couple of extra switches).
