Information on update: Warning has been extended east along the south coast into Kent whilst being removed from Wales and parts of southwest England to reflect the area most likely to see heavier rainfall. An area of low pressure will migrate northeastwards across England on Thursday. Whilst the exact track is uncertain, rain will become persistent and heavy through the day, before clearing to the north through the evening and night. Accumulations of 20-30 mm are expected fairly widely, in some places falling in just a few hours, with the potential for 40-50 mm in a few isolated spots. Given the saturated ground, this may lead to some surface water flooding. For further details see https://www.metoffice.gov.uk/weather/warnings-and-advice/uk-warnings
