New floodgates are being fitted to the Afon Erch near the town's harbour, and 400 metres of sand dunes - damaged in 2000 by a severe storm - are being strengthened.
In northern Indiana on Tuesday, sand whipped by high winds spawned by the far-reaching storm forced cancellation of classes at one school, the Associated Press reported.
Projects outlined on the site include a map of places that need sand-bagging, ways for people to sign up and help, and after-storm parties, set up to raise money.
