Thunderstorms and heavy rain are set to hit Newport tomorrow, the Met Office has warned.

A yellow weather warning is in place for much of Wales, with strong winds, flooding and lightning strikes possible.

The warning will come into effect tomorrow morning at 4am and will run until midday on Wednesday.

This is what the Met Office are warning to expect: 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.

Where flooding or lightning strikes occur, there is a chance of delays and some cancellations to train and bus services.

There is a slight chance that power cuts could occur and other services to some homes and businesses could be lost.

There is a small chance of damage to trees by strong and gusty winds.

A Met Office spokesman said: “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.”
