Although a thunderstorm can sure put a damper on things at the campground, if you can stay warm and dry, it can be tolerable. Here's how:

• Use a ground cloth under your tent.
• Set your tent up on higher ground.
• If your floor leaks, use a tarp inside the tent.
• Use a rainfly that gives good coverage.
• Seam seal your tent and rainfly.
• Take raingear.
• Vent your tent to allow condensation to escape.

Take off all wet clothes when entering the tent. If your tent has a vestibule, you are all set, otherwise set aside an area inside the tent to stow wet gear until you get an opportunity to hang them out to dry. Avoid camping when you have advance warning of foul weather, particularly in tornado alley, the mountains, or hurricane areas.
