The Met Office have announced a yellow warning for thunderstorms in Wales, saying that it could cause flooding in some areas.

The storms will break a ‘mini-heatwave’ with parts of Wales currently basking in temperatures in the high 20s. The heat will however start easing off by the middle of the week.

South east and mid Wales are likely to see thunderstorms later Wednesday through to Friday with the potential for travel disruption and flooding.

“Although there remains significant uncertainty in location and timing, areas of thunderstorms are expected to move northeast across parts of England and Wales from late Wednesday through to Friday morning,” the Met Office said.

“Whilst not all locations will be affected, some intense thunderstorms may occur during this period with torrential rain, hail, frequent lightning and strong gusty winds possible.

“Rainfall totals of around 30 mm could fall in an hour, with some locations potentially receiving around 50 mm in 2-3 hours, although these will be fairly isolated.”

The Met Office are warning that:

  • There is a small chance that homes and businesses could be flooded quickly, with damage to some buildings from floodwater, lightning strikes, hail and strong winds
  • Where flooding or lightning strikes occur, there is a chance of delays and some cancellations to train and bus services
  • Spray and sudden flooding could lead to difficult driving conditions and some road closures
  • There is a small chance that some communities become cut off by flooded roads
  • There is a slight chance that power cuts could occur and other services to some homes and businesses could be lost

For the moment however, Sunday is predicted to be the hottest day of the year so farm with the warm temperatures expected to last through Monday and Tuesday too.
