Valid to: 2200 on Mon 24 Aug 2015
Areas of rain will run into the UK from the south on Monday morning, with some persistent and heavy rainfall in places. During the afternoon there is an emerging focus for the heaviest of the rain to be in parts of southeast England and East Anglia, where some intense, slow-moving thundery downpours are looking increasingly likely – although as often in these situations, some places will miss the heaviest rain. The public should be aware of the risk of flooding, including disruption to travel. In addition to this there is the potential for strong winds, particularly around exposed coastal areas.
This warning is an update, to increase the focus on southeast England and parts of East Anglia and to raise the probability of medium impacts on the Risk matrix. A further update may be expected early on Monday.
Chief forecasters Assessment:
A low pressure system is expected to run into the UK from the south on Monday morning, bringing areas of heavy rain particularly across some southern areas of England. There remains some uncertainty over the locations of the heaviest rain but with the potential for 20 mm to fall quite widely and with 40 to 60 mm possible in some places, much of this falling in a few hours. Latest indications are that the most intense rainfall may be expected across parts of southeast England and the southern portion of East Anglia during the afternoon, as brightening skies supply extra energy, leading to development of slow-moving thundery showers.
