In Pontypridd, Rhondda Cynon Taf, residents said lessons were not learned from Storm Dennis, which left much of the town under water in 2020.
Resident John Pockett said: “The one thing I think is appalling in this is: where was the warning? Nobody had heard anything at all.”
On Monday, the clean-up operation continued as 30 schools were closed, most in Caerphilly and Monmouthshire, and flood alerts remained in place.
These included two severe flood warnings, external, with significant risk to life and disruption to the community, near the River Monnow in Osbaston and Skenfrith in Monmouthshire, but these have since been lifted.
A landslip near Pontypool, Torfaen, led to the closure of the Newport to Shrewsbury train line, Network Rail said.
