Wild storm there.
I had a BBQ contest I did quite a few years back that was like that. Luckily we had some warning and some rope, so our canopy got tied down to our trailer with the smoker and my buddy's truck. Had about 300 lbs of meat and myself on one of the open corners and the same with my buddy on the other. We fared well, but had some friends up the hill that had a little 10' x 10' tied to their smoker and coolers and held on. All but one of the 4 guys was 250 lbs or larger, and all, including the smoker and coolers got lifted about 3' off the ground and tossed.
