The Met Office has issued a yellow warning of thunderstorms affecting North Wales tomorrow

The warning is in place for Friday, August 6 from 4am onwards.

The Met Office expects heavy showers across much of the UK during that time, including in Conwy, Denbighshire, Flintshire, Gwynedd and the Isle of Anglesey.

These showers and thunderstorms will be slow-moving and may cause localised surface water impacts. Rainfall totals will vary considerably and not all locations will be affected by the heaviest downpours.

But there is potential for between 20 and 30mm of rain in a short space of time and, during the course of the day, there is a chance that some places could see as much as 80 to 100mm build up.

What to expect:

• There is a small chance that homes and businesses could be flooded quickly, with damage to some buildings from floodwater.

• 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.
