Camping in a campground in Germany when a sudden wind came up while I was in the tent. It also rained so hard that my partner was left under a veranda less than 10m away but unable to dash for the tent without getting soaked. I was left inside the tent trying to support the tent poles from bending close to the floor as the wind gusted (it was a tunnel tent with 3 poles). It lasted less than 10mins but the danger was of being blown tent and all into the lake just metres away and unable to exit the tent.
