WE'VE had a long run of summer sun but the weather is about to change!

The Met Office has issued a yellow weather warning for thunderstorms this Friday - areas affected include Conwy, Denbighshire, Flintshire, Gwynedd, Isle of Anglesey, Powys and Wrexham.

The warning is in place from 11am Friday (July 13) and 8pm.

A spokesperson for the Met Office said: "Many places will be dry, however there is the potential for heavy and slow-moving thundery downpours in places.

"Some flooding of a few homes and businesses is likely, perhaps leading to some damage to buildings.

"There is a good chance driving conditions will at times be affected by spray and standing water, leading to some minor journey delays.

"Some short term loss of power and other services due to lightning strikes is possible."

Heavy showers are expected to develop quite widely across parts of England and Wales later Friday morning and through the afternoon.

The spokesperson added: "Some of the showers are likely to become focussed into slow-moving bands, particularly over southwest England, with some locations receiving around 20mm in an hour.

"As is the nature of showers however, many places within the warning area will miss them altogether, and have a dry day."
