Met Office - Storm Ciarán

Met Office chief meteorologist Dan Suri said: “Tomorrow, ahead of Storm Ciarán, a squally cold front will move eastwards across southern and southeast England bringing bursts of heavy rain and coastal gusts of 60-70mph, mainly from Dorset eastwards.

“Wind and rain warnings associated with Storm Ciarán are in force from Wednesday night onwards into Friday, with further updates possible on Wednesday. These include amber warning for winds for southwestern parts of England and Wales Thursday early hours and morning and the far south and southeast of England Thursday daytime and early evening. Storm Ciarán is expected to bring very strong along southern coastal areas of England in particular where gusts of 70 to 80mph are possible, gusts perhaps exceeding 85 mph in the most exposed locations. Further inland, gusts could reach up to 50 or 60mph.

“As well as strong winds, this deep low pressure system will bring heavy rain to many parts of the UK. Much of southern England and south Wales, as well as parts of north Wales, northeast England, southeast Scotland and perhaps the east of Northern Ireland look to see the wettest conditions between Wednesday evening and Friday morning. 20-25 mm of rain may fall quite widely, with 40-60 mm possible over higher ground. Some parts of south Wales and southwest England may see 80 mm of rain. This rain will fall on already saturated ground, bringing the risk of flooding."
