We ahd tornadoes! (were right on coast though).
Rain yes, not a problem, mone and Mums were Ok (Gelert and Khyam)
windsa different thing- NO tent on our site survived without a re-pitch other than the rigid steel ones. One Outwell was completely destroyed (a minnesota iirc). Ours survived but took a bit of damage . (seemed minor though as a poor boy was lost at sea nearby the same night - 17 years old).
We are buying the only tent on the whole site that looked pristeen and perfect on the Monday for next year, a Colaman Weathermaster Galileo. Bring on the tent!
