    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.
