The Met Office have issued a yellow weather warning for heavy rain, valid from 00.15 on Friday to 23.45.
Heavy showers and thunderstorms are likely to spread from the south across some southern and western parts of England, and also Wales, on Thursday night – the risk then continuing through much of Friday.
Many places will miss these but the public should be aware of the potential for isolated disruption due to surface water flooding, lightning strikes and hail.
