‘With the ground already saturated, this may lead to some flooding. Strong winds are also likely, with gusts 40 to 50mph possible along coasts.’

Torrential showers and flooding have caused ‘very heavy delays’ on the roads around Havant and Farlington, according to traffic monitoring system ROMANSE.

Tomorrow’s warning will be implemented from 5pm until 6am on Thursday. Forecasters say flooding and travel disruption is possible.

Heavy rain and the odd thundery shower are forecast from 5pm tomorrow, with downpours expected to last into Thursday morning. Peak temperatures will be at 13 degrees Celsius, with wind speeds reaching 41 at their highest.
