It's fine. I crosspost and get dinged by moderators of other forums, from time to time. I figure if it really is topical in both forums, it ought to stay in both.

Thanks for pointing it out.

You Rock Tom... Thanks!!!

   Yo !

I just had a freaky wind/turbulence experience at a terminal wall in Italy. A couple of people jumped before me and reported light South wind on landing. I exited about 2 minutes later and encountered very strong turbulence during the second half of the flight - strong enough to continuously throw me off balance and severely degrade the glide. I flew to what i thought was the upwind side of LZ and pulled high. To my great surprise i immediately started backing up into the woods, and front risers didn't help at all. I barely made a small clearing by the road well behind LZ. In 3 minutes it took me to exit and fly down the wind did 180 and picked up enormous speed. A couple minutes later it was a full-blown storm, and a small storm cloud came from around the corner to drop some rain. 15 minutes later it was fine again and another group of jumpers landed uneventfuly. I have been to this place a lot, and still got cought completely unprepared by such a rapid change of the wind. I used to think that a wingsuit gives you immunity from the weather - and it does when you know what's going on... but it isn't IFR-equipped and shit still happens!

bsbd!

Shows again that this wall is not "easy"... (as I hear people sometimes)

Had my experinces there too. One of those was an evening jump, wind only at altitude coming from behind-right looking down from the exit. Pulled normally at about 20' for landing at the "parete zebrate", where after opening strong downwind sucked us down. Useing the toggles, the canopy did not respond. Luckily only a very hard landing on the base of the wall was the result: "Mind the wind!"

The wind situation at the terminal wall in Italy is very particular ! The wind from the lake (South) generally rise half morning and drop at sunset particularly in summer.
The situation are different if the wind come from nord or are perturbation wind, in this case can blow for whole day .
Are very common have wind situation different between exit point/fly zone/and landing area.
I have often experienced this situation and generally when the wind have various direction (Stratifield) the turbolence are very common, particularly at sunset.
I don't no the real reason of this situation, i presume be tied at valley morphology and lake presence !
