Storm Benjamin is expected to cross the south of the UK later Wednesday and early Thursday.
Warning times: Midnight tonight until 6 pm on Thursday 23 October.
The Met Office says that 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. As the main rainband clears eastward during Thursday, it will be followed by frequent heavy showers in some western areas. Totals are expected to reach 20-30 mm quite widely, with some places seeing 30-50 mm. There is a chance a few places could exceed this, most likely over North Devon and Cornwall.
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.
