A MET Office yellow warning for thunderstorms has been issued for parts of North Wales today (May 21).

The Met Office’s warning added: "Heavy showers and thunderstorms are expected to develop during the afternoon across parts of southwest England, Wales and the West Midlands before slowly dying out during the evening.
