This Evening and Tonight

Isolated, slow-moving downpours should ease, leaving dry weather for most with late sunny spells. It should become generally dry by the early hours, with some low cloud moving into eastern parts on the northeasterly wind, while western areas stay clearer.

    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.
