I agree with all of the above.
You will learn about your own particular awning from experience. Assuming this is a brand name awning, like a Carefree, there are some things that are fairly certain.
First - A little wind is not a problem.
Second - A little rain should not be a problem.
Third - Unless there is a promise of thunderstorms, leaving the awning out at night is not be a problem.
Fourth - Gusty winds are a bigger problem than constant winds. So that turbulence that comes just before a storm is not to be ignored.
Fifth - An electric awning that cannot be lowered on one side is not always a problem in terms of pooling of water. It depends on how much slope there is. I have never actually measured ours, but I would very roughly estimate it is something in the neighborhood of around three feet, give or take maybe six inches. (Trailer is 12 foot high, awning is mounted somewhere around the 11 foot mark, and I can touch the awning at its lowest point/maybe 8 foot above the ground) So 11 minus 8 is right around 3 feet. In contrast, the guy that was camped across from me last winter had an electric awning that had almost no slope. It was an easy 9 foot off the ground at the lowest point, maybe even more. The bottom line, my awning has never collected water in the past five years, and we are snowbirds, so our awning has seen a lot of rain. My neighbor, on the other hand, retracted his awning every time it rained.
