The frame can stand up to snow and maybe a relaxing hurricane, but the bottom skirting doesn't really do much. If it could be anchored to the poles correctly, I'd say it would be helpful. I bought it to store my motorcycle. I wish I had gotten a bigger one so I could work on my bike this winter. Waterproofness is great. No leaks. Assembly was almost idiot-proof. Match the labels on the poles. Simple.
