Agree with old coot, stay dry. Although I do tie my awning down at each end once extended. I use two large screws into the ground under each end of awning. The screws have a triangle on top, normally for dog leash or something. I attach a spring (like the ones used on trampolines) for some wind bounce and then run a rope with a clip on each end from the spring to awning corner. The spring gives some flexibility when windy although in high winds roll-er-up. Drop one side slightly during a rain, although some of the new awnings auto dump with weight.
