The weather warning is in place from 10am to 7pm across the Portsmouth area, the south of England and the whole of Wales.

Heavy showers are likely to take place from 11am. The spokesperson added: ‘A narrow band of rain, heavy at times and perhaps briefly intense, will move eastwards late on Thursday morning and into the afternoon, clearing Kent during the evening.

‘Ten to 15mm is likely to fall in a one to two-hour period, with around 20mm in a few places. With saturated ground, this is likely to lead to a fair amount of surface water on roads and flooding in one or two places.
