Strong winds and heavy rain from storm Bert battered much of Britain again on Sunday, causing “devastating” flooding in particular in Wales, with around 100 flood alerts in place nationwide, authorities said.

In Rhondda Cynon Taf county in south Wales, 200 to 300 homes and buildings were flooded, a local councillor said, prompting the authorities to declare a “major incident” in the area.

A body was found near the river Conwy where search operations took place after a 75-year-old man went missing Saturday after going out to walk his dog, Welsh police said. The victim has yet to be officially identified.

At least three deaths were reported on British roads on Saturday, though they could not immediately be linked to the extreme weather. Among them was a victim in the county of Hampshire aged about 60 who was killed after a branch fell on his car.

Welsh Prime Minister Eluned Morgan said the impact of the flooding had been “absolutely devastating” in the county, where 80 per cent of the usual amount of rain for November fell in just 48 hours.
