Heavy downpours have caused disruption across Wales amid an amber weather warning
More than 50 areas of Wales remain at risk of flooding after a day of severe weather, Natural Resources Wales (NRW) has warned. Heavy rainfall caused significant disruption across south and west Wales on Monday with a rare amber weather warning in place.
Roads were closed due to the flooding and there were a number of rail cancellations. The rest of Wales was covered by a yellow rain warning and also saw torrential downpours. The Met Office warned that over a month’s worth of rainfall was expected to fall within 24 hours in some areas.
BBC weatherman Derek Brockway said that the areas which saw the most rainfall in 24 hours was Cwm Dyli Hydro Power Station in Eryri, where 127mm of rain fell. Trehebert in Rhondda Cynon Taf was also hit badly, with 91mm of rain recorded.
As of 6am on Tuesday morning (December 2), nine NRW flood warnings remain in place.
The rivers covered by these warnings are:
- River Towy at Carmarthen Quay, Carmarthen

NRW say “immediate action” is required in these areas, with flooding to some properties expected.
