Record-breaking flooding is becoming “the new reality” for communities, according to Natural Resources Wales (NRW).
Two years after storms wreaked havoc across Wales, the environmental watchdog warned urgent action was needed to prepare for climate change.
“The need to act now to prepare for climate impacts is more pressing than ever,” it said.
Storms Chiara, Dennis and Jorge led to record rainfall in February 2020.
Eleri Griffiths, Plaid Cymru councillor for the Rhondda ward in Rhondda Cynon Taf where 44 houses were flooded, said people had been traumatised by the impact of the storms, just before the pandemic hit Wales.
“Large parts of Rhondda Cynon Taf were completely unrecognisable… and of course the clean-up operation took months, into the period where we entered the Covid lockdowns,” she said.
“So it was certainly a time of extreme trauma for many people.”
Ms Griffiths told BBC Radio Wales Breakfast people in her own ward who had been flooded were still “none the wiser” about any measures taken to make sure it would not happen again.
“Trehafod people are still waiting for answers. I spoke to one resident in Trehafod yesterday who was flooded and he described to me how him and his wife worry and have anxiety every time it’s raining.
“The children are worried. They have conversations about whether should they move half of the furniture upstairs whenever there’s any sort of flood alert.
“And he said ‘Well we still haven’t had answers, have we? What’s changed? Nothing’s changed’.”
She added that public bodies needed to “react a lot smarter and a lot quicker to the climate changing”.
“We know that there’s risks of this happening again, as Natural Resources Wales reported,” she said.
