    The yellow weather alert has been issued for parts of southern England from tomorrow (18 June) until Wednesday (19 June).

    Thunderstorms could potentially take place during Tuesday evening, developing more widely across the southern region overnight.

    The storms may later merge into areas of more prolonged and widespread rain on Tuesday night, with around 15 to 30 mm of rain expected to fall widely, and up to 50 mm in a few locations.

    The early hours of Wednesday will see a drier interlude, before further thunderstorms may develop in a few places during Wednesday afternoon. Rain and flooding are likely to pose the largest impact, while hail, lightning and gusty winds will be additional hazards.
