Dry for many during the evening, but cloud thickening with an increasing risk of heavy, thundery downpours across all areas overnight, as well as mist and fog patches.

    Although not all areas will be affected, thundery showers or areas of heavy rain are likely to affect some southern and eastern parts of England late on Saturday evening and on Sunday. The main focus for thundery downpours looks limited to the southeast corner of England overnight but then becomes rather more widespread during Sunday afternoon and evening. Lightning may be an additional hazard.

    The public should be aware of the risk of localised impacts from heavy rain and flooding, which may affect travel and some outdoor events.

    Further areas of heavy rain or thundery showers may affect parts of southern and eastern England on Bank Holiday Monday, with an additional risk of strong winds developing. It should be noted that there is a larger than average uncertainty in the areas likely to be affected, with updates to this Alert very likely. Meanwhile, the public should be aware of the risk of further localised flooding and impacts on holiday activities.
