An area of very strong winds is likely to extend east across southwest England and parts of central southern England on Monday morning. Gusts of 60-70 mph are likely widely, with 80 mph gusts in exposed coastal areas, particularly Cornwall and North Devon, and also along the South Wales coast and through the Bristol Channel. Some very large waves are also likely to affect many coasts, in particular north coasts of Cornwall and Devon.
Winds should gradually ease through the afternoon and evening. This warning has been updated to include a greater part of the South Wales coast.
Please be prepared for disruption to travel as well as possible damage to trees and structures, and interruption of power supplies.
This is an update to the warning to extend the amber area to cover more of the Bristol Channel, including Cardiff and Bristol, and also English Channel coasts of Sussex and Kent.
Chief forecasters assessment:
An area of low pressure is expected to move eastwards across the UK on Monday with a swathe of very strong winds around its southern flank, which will affect parts of southern Britain. The winds are likely to be very gusty at times, particularly in association with heavy showers running across these areas.
There remains some uncertainty in northward and eastward extent of the damaging winds as well as the peak strengths and so this warning will be kept under
