Ours is tilted so in rain the water runs off the back of the awning. Its a noticeable downslope from front to back Though it does not have a wind sensor, it will close on its own, if the wind lifts it. I raised it with a broom, moved it up and it closed. I still close it if the wind starts, no reason to look for trouble. Haven't really been in much rain with it, some, but only light rain.
