On Monday, the clean-up operation continued as 28 schools were closed, most in the Caerphilly and Monmouthshire local authority areas, and flood alerts remained in place.
These included two severe flood warnings with significant risk to life and disruption to the community near the River Monnow in Osbaston and Skenfrith in Monmouthshire.
First Minister Eluned Morgan said the impact of Storm Bert has been “absolutely devastating”.
“The severity and frequency of these events is something we all need to be aware of,” she said, adding that “hundreds of millions of pounds have been put into flood defences in Wales over the past few years”.
Council leader Andrew Morgan said he was “surprised” a red warning was not in place for Storm Bert.
“During Storm Dennis we did see an amber warning well in advance, and a red warning issued in the early hours,” he said.
He also said that between 200 and 300 properties were affected, with the rainfall surpassing some records set by Storm Dennis.
He added that one bridge that was under construction, and which was replaced after Storm Dennis, was completely washed away.
