I stayed at the RV Park in Pacifica that is right on top of the cliff overlooking the ocean. It was a nice sunny day and I assume a lot of the other RVer's were in San Francisco for the day. I was in the RV and had not put my awning out, and I guess what would be called a "microburst" came along up the cliff from the ocean. I don't know what the wind speeds were, but it shook my motorhome pretty good. Basically came out of no where, lasted about 45 seconds at the most, and then the wind calmed back down to a slight breeze. I walked around the park afterwards and saw at least 10 awnings damaged. Later that evening when people were getting back and trying to figure out what happened, I walked around the park again and told a few of them what happened.
I don't know if it was necessarily the speed of the wind that did the damages, versus the fact that is was swirling as it came through and I assume had a strong updraft to it. I never left my awning out again after seeing that. But that is the advantage to an electric awning as you can put it in or out in under a minute.
