The Met Office has issued a yellow weather warning for thunderstorms across west Wales on Thursday.

The warning runs from 6am until 10pm on Thursday, 27 August and says: "A band of thunderstorms and heavy rain will move north across England and Wales, perhaps becoming slow moving in the afternoon and evening.

"Accumulations of 20-30 mm in three hours can be expected fairly widely and up to 50 mm in a 12 hour period can be expected in places.

"There is a small chance that some places may see more than 50 mm in three hours and more than 75 mm through 12 hours, especially over east facing high ground. Lightning and hail of 1-2 cm will also be hazards."

There is a small chance that homes and businesses could be flooded quickly, with damage to some buildings from floodwater, lightning strikes, hail or strong winds.
