Widespread gales are likely to develop across the area late on Thursday evening and last much of Friday. The worst of the winds are likely to transfer across northwest Wales and much of northern England during the day on Friday bringing gusts of 60 to 70 mph widely with locally 80 mph gusts affecting west coasts and high ground for a time.
The public should be prepared for disruption to transport and power supplies.
Another deep area of low pressure now developing over the Atlantic will bring another spell of very windy weather across the UK as it tracks northeastwards, crossing northern Scotland during the second half of Friday. To the south of the low pressure centre, a swathe of severe gales is likely to cross northwest Wales and much of northern England. The worst of the winds should ease on Friday evening.

Widespread gales are expected to develop on Thursday night and last much of Friday bringing gusts of 50 or 60 mph inland and gusts to 70 or 80 mph to some coastal areas and high ground. This warning has been updated to extend the area slightly further south across England and to include all of Northern Ireland.
The public should be aware of the potential for disruption, especially where the high winds are combined with heavy rainfall. Please watch for possible updates to this warning, especially those who have travel plans.
Another deep area of low pressure developing over the Atlantic Ocean will bring another spell of wet and very windy weather across the UK as it tracks northeastwards past northwestern Britain later on Thursday and during Friday. Winds are expected to increase across the area during Thursday evening and night. Peak winds are thought most likely to occur during the early hours of Friday and Friday morning with the highest gusts probably being over Irish Sea coastal areas. However an area of severe gales is also likely to track across much of northern England during Friday.

Spells of rain affecting the UK late Thursday and Friday are expected to be heavy at times with 10 to 20 mm falling quite widely. Locally in excess of 25 mm is likely over parts of Wales, Northern Ireland and southern England by mid-morning whilst more than 40 mm are expected over parts of Scotland along with Dartmoor.
The public should be aware of the potential for disruption, especially where ground is already saturated, and high winds are combined with heavy rainfall. This warning has been updated to remove northern England where impacts from rain are likely to be less significant. However, severe gales have the potential to cause problems here (please see separate wind warnings).
Another deep area of low pressure developing over the Atlantic Ocean will bring another spell of wet and windy weather across the UK as it tracks northeastwards past northwestern Britain later on Thursday and during Friday.
Relative to recent storms that have affected the UK, Friday's depression is looking less intense and, for most, the extent of associated impacts are currently thought to be less severe.
Over Scotland precipitation is likely to start off as snow in places with some brief accumulations above about 250-300 m and remain as snow above 600 m or so in the Highlands. Meanwhile, below approximately 600 m snowmelt will increase the contribution to Scottish river catchments.
