The Classic poled Glawning handles high winds better than the AIR and is often the last tent standing. In any strong wind, run the guy ropes out as far as you can, tension them well, peg at 45 degrees and take the stove flue down.
Before the wind arrives
Run the guys out as far as possible and tighten them well.
Use pegs suited to the ground, driven in at 45 degrees away from the tent.
On a GlawningAIR, raise the pressure to around 7 PSI.
Take the stove flue down, and don't light the stove if the canvas is moving significantly.
Classic or AIR?
The poled Glawning copes better with gales. AIRs move more in strong gusts.
When to take it down
It's still a tent. In extreme conditions it's sensible to take it down to protect it.
