Met Office issues new weather warning for heavy rain and flooding

The Met Office has issued another yellow weather warning for rain as flooding downpours are set to continue in the wake of Storm Dennis.

After a weekend marred by devastating flooding, the stormy spell will continue to hammer pockets of the country beginning at the middle of the week.

The weather warning, issued for north-west and south Wales, will come into effect at 6pm on Wednesday and last until 3pm on Thursday as another Atlantic storm system moves over the UK.

This further spell of rainfall is likely to become particularly prolonged over areas of high ground, leading to the chance for flooding and travel disruption.

“Whilst there is more uncertainty over the rainfall totals for south Wales, there is a small chance that 50-60 mm could fall here in 24 hours,” the Met Office said.

“There is higher confidence in the rainfall for north-west Wales, with between 70 and 100 mm of rain most likely.”
