A THUNDERSTORM warning has been extended across the whole of North Wales.

On Monday, the Met Office issued a yellow alert which was due to come into effect at midday on Thursday (August 1), and last for the remainder of the day. It was due to cover North East Wales. 

But today (Tuesday, July 30) the Met Office has extended the weather warning in terms of time and locations.

The warning is now in place from midnight on Thursday (lasting the full 24 hours) and it now also includes Conwy and Gwynedd.

Forecasters have been warned of possible travel disruption, flooding and power cuts during any potential storms.

A Met Office forecast states: "An area of showery rain is likely to develop and move northeastwards across parts of Wales, the Midlands and northern England. This will be heavy and perhaps thundery at times, persisting through Thursday morning before easing towards midday.

"Some areas could receive rain accumulations of 25-50 mm over the course of a few hours. Scattered heavy showers and thunderstorms are then expected to develop through Thursday afternoon and evening across parts of central, southern and eastern England, and perhaps also south Wales."
