Southampton, England, United Kingdom Severe Weather Alertstar_ratehome

Information on update: Reference to Storm Benjamin, and some small changes to areas at greater risk of the higher totals mentioned in further details. Storm Benjamin is expected to cross the south of the UK later Wednesday and early Thursday; confidence in its track has improved compared to yesterday but still remains lower than usual for this type of weather system which leads to continued uncertainty over the corridor of highest rainfall totals.

That said, an extensive and in places heavy swathe of rain will move into southwestern Britain later Wednesday and spread quickly northeast, with totals by early Thursday morning of widely 20-30mm, and for some places 30-50mm. There is a chance a few places could exceed this, most likely over North Devon and Cornwall and also within a broad area encompassing Lincolnshire, Humberside, East Anglia and East Midlands.

In association with the rain, conditions are expected to turn windy with gales, initially along south-eastern coasts, but more widely across southern Britain during Thursday daytime.
