We strongly suggest that you need check and install this item firstly before you go to camping. It would save your installation time. Because we cannot be there to set this up for you, and we have no control over your local weather, wind, or soil conditions, it is ultimately up to you to determine if your assembly and anchoring of this umbrella is sufficient. Other tarp are recommended under heavy rain. If you feel it needs to be held down better, you may need to purchase additional anchoring materials (stakes, weights, screws, etc.) locally.
