A weather warning has been issued for thunder storms across Mid and North Wales later in the week – with up to 10cm of rain possible in some places.

The Met Office has this morning issued a yellow warning for thunder on Friday, 6 August between 10am and midnight on Saturday.

The Met Office says: “Heavy showers are expected across much of the UK on Friday.

“Within the warning area 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 showers.

“However, where the showers do occur there is potential for 20mm to 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 80mm to 100mm build up.”

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

Localised flooding could cause difficult driving conditions and some road closures.
