I was recently camping at Dolls flats (near Roan Mt, TN) close to the edge of the woods, when a heavy rainstorm blew in. The tent was set up so the long edge was perpendicular to the wind (I wasn't expecting the storm). The main problem was that rivulets of water were running down the sheltered side of the tent and instead of dripping off the edge of the tent, they were running back into the tent along the mesh towards the edge of the bath tub. Eventually the mesh got so sodden, that it weighted down the edge of the bath tub to the ground and the water started coming into the tent.
I tried adjusting the bath tub with the tensioners in the vestibule, but to no avail. The bathtub shape is delicate,even in good conditions a wayward map can distort it.
The heavy rain didn't last long so not too much water came in thankfully.
Some of the problem may be due to the strong wind coming in one side of the tent and exiting the other, pushing down the mesh as it exits.
What can I do to mitigate this problem next time?
