South Wales storms 1972-ish ?

[valiant]

My wife tells me that c.1972 she was staying in a caravan in Saundersfoot, South Wales when there was a hail storm that broke windows, followed by a night storm that tossed caravans around like matchboxes.

She slept through it - but in the morning the site was a scene of utter devastation. Is this a well documented event? It took place in "Potters holidays" ie the June fortnight when the pottery workers of N. Staffs took their summer break.
