    Although some places will remain dry during Saturday, scattered heavy showers and thunderstorms, already across parts of the southeast of England, are likely to develop more widely through the afternoon and continue into the evening, with some localised intense downpours likely.

    This update expands the warning area and brings the start time forward by an hour. Additionally, a greater probability of larger rainfall totals, means that isolated medium impacts are now judged more likely. Please be aware of the potential for surface water flooding, whilst hail and lightning will be additional hazards for travel and outdoor activities.
