On one glider flight, we lined up nicely with the updraft front feeding an oncoming CB and had a lovely time swanning back and forth. We left in time to get the bird safely tucked in the hangar before the gusts and rain got to our field
I know of one glider that was written off by an instructor and candidate who landed in the rain and abandoned the glider which then got blown on its back
Had they stayed in it on the ground and worked the controls as did I42, the glider would likely be still flying.
I have tie downs in the back of my glider.
Getting into wave exposes you to going through rotor. I had to give up as my tummie butterflies got fidgety
