What I do is lower the side of the awning that the wind is coming from. This way it can't get under it and lift it. You also need to watch the flapping. Continued flapping could start tearing the end up on the trailer. With the rain just lower one side, preferably the side that the ground is sloping to so the water doesn't run back into your site. Make sure it's low enough to drain the water. Even with it lowered a little it can still collect enough water to bend the tube!
I do the same to keep the wind from getting underneath it. Ours was out 24 hours a day for 60 days while in FL. Rain and some moderate wind. If I expected some really strong winds I would have rolled it up.
