Outbreaks of heavy and at times thundery rain are expected to run northeastwards across southern England during the rest of Thursday evening into the early hours of Friday. The public should be aware of the risk of localised surface water flooding and disruption to travel. Lightning could prove to be an additional hazard.

The rain should clear away eastwards later in the night.

An unstable southwesterly flow covers southern England. Outbreaks of heavy, thundery rain developing over the English Channel are expected to affect southern England overnight. The thundery downpours will clear eastwards becoming restricted to areas east of the Isle of Wight by 01:00 and then clearing other parts by 04:00. Although, as is usually the case with showers, not all parts will see the heavy rainfall where it does occur 25 mm of rain could fall in less than an hour locally with 30-40 mm falling in 3 hours or less in places.

The public is advised to take extra care, further information and advice can be found here:
