THUNDER and heavy winds are set to sweep across west Wales in the early hours of tomorrow morning, with forecasters issuing a weather warning.

The Met Office has this morning issued a yellow warning for thunderstorms across all of Wales from 4am until midday tomorrow (Wednesday).

A brief period of heavy rain, thunderstorms and very gusty winds may cause some disruption, the warning says.

There is a small chance that homes and businesses could be flooded quickly, with damage to some buildings from floodwater, lightning strikes, hail or strong winds

Spray and sudden flooding could lead to difficult driving conditions and some road closures in some areas too.

The Met Office says: “An area of heavy rain and thunderstorms will move quickly eastwards across Wales and southwestern England into parts of central, southern and eastern England during Wednesday morning.

“Many areas will see a spell of rain whilst some places will be affected by thunderstorms bringing a brief period of heavy rain, lightning, and strong, gusty winds with hail also affecting some spots. Gusts will tend to peak at 40-50 mph, but whilst very unlikely in any one place, much stronger winds are possible here and there, then potentially damaging some structures.”
