A yellow weather warning has been issued as heavy rain looks likely to cause disruptions across the region.

The Met Office issued a yellow weather warning with most of southwest Wales a chance to get up to 80mm of rain in as little as three hours on Monday (August 14).

The heavy rain warning will be in place virtually all day, running from midnight on Sunday until 9pm on Monday.

It covers most areas of southwest Wales including Carmarthenshire, Ceredigion and Pembrokeshire.

The heavy rain could cause flooding, road closures and leave homes without power for periods of time.

What to expect from the yellow weather warning in south west Wales

The Met Office said the yellow weather warning for southwest Wales is due to heavy and persistent rain.

As a result of the heavy rain, the Met Office said to expect:

  • Flooding with the potential to cause damage
  • Flooded roads could temporarily cut off some communities
  • Difficult driving conditions and road closures due to spray and flooding
  • Delays and/or cancellations to train and bus services due to flooding
  • Power cuts and loss of other services

A Met Office spokesperson added: "Rain is expected to develop across southwest England and south Wales on Sunday evening and spread northeast to affect many parts of England and Wales through Monday before easing and clearing into the North Sea on Monday night.

"Within this larger band, a corridor of heavy, persistent and perhaps thundery rainfall is expected to develop.

"There is some uncertainty in the track of this heavier rain but 20-40 mm of rain is expected to fall in many areas within the warning area, with a chance of 60-80 mm falling in a few places, much of which would fall in 3-6 hours.

"At this stage, this very heavy rain appears more likely to fall over northwest Wales and northwest England."
