As predicted, there have been heavy thundery downpours across south-east England and the London area this morning, with parts of Kent seeing 10mm of rain in one hour. Some areas of London also saw 5-10mm of rain across the morning.
The risk of heavy thundery showers continues into the afternoon. However, as is the nature of showers, and as we saw in Bournemouth last week, some areas will have heavier bursts than others. Some parts of London, including Heathrow, have only had 1mm of rain so far this morning while Hampstead has had 9mm in an hour.
