A flood caused by the 'Dambusters' style bombing attack on the Nant y Moch Dam above Aberystwyth wiped out much vital infrastructure, but was rebuilt quickly.
The flood had been created to launch an ark being built on the school playing grounds to give the druids access to the semi-legendary (actually real in this universe) Cantref-y-Gwaelod (Cantre'r Gwaelod) .

She wrote a book about forensic meteorology called "Red Sky at Night", which Calamity used to solve the riddle of the Nanteos fire.
