12:00 on Monday until 23:55 on Monday
A spell of very windy weather is likely on Monday in association with ex-Ophelia.
Road, rail, air and ferry services may be affected, with longer journeys times and cancellations possible. Power cuts may occur, with the potential to affect other services, such as mobile phone coverage.
Some damage to buildings, such as tiles blown from roofs could happen, perhaps leading to injuries and danger to life from flying debris.
Coastal routes, sea fronts and coastal communities may be affected by spray and/or large waves.
The warning has been updated to delay the onset time of the strong winds and increase the likelihood of the event occurring.
Chief Forecaster's assessment
Very strong winds are forecast to affect western parts of the UK during Monday.
Southerly winds are most likely to gust between 55 and 65 mph across much of the warning area with the potential for gusts of 80 mph in coastal areas, particularly in Northern Ireland. These strong winds are forecast in association with the northward track of ex-Ophelia across or near to the west of the British Isles.
Heavy rain is also possible in association with this system with northwestern UK most prone at this stage.
