Amber warning

- This means there is the possibility of travel delays, road and rail closures, power cuts and the potential risk to life and property.

Strong and gusty southerly winds may cause disruption to transport and infrastructure
What should I expect?
- Some delays to road, rail, air and ferry transport are likely
- It’s likely that some coastal routes, sea fronts and coastal communities will be affected by spray and/or large waves
- Probably some bus and train services affected, with some journeys taking longer
- Some short term loss of power and other services is possible
- Delays for high-sided vehicles on exposed routes and bridges likely
What should I do?
Further detail
A brief spell of strong and gusty southerly winds will likely coincide with rush hour on Friday. Gusts of 45-55 mph are likely across the warning area, with exposed coasts and hills of counties Down and Antrim could see brief gusts of 65 mph.
Winds quickly ease from the west late morning.
What Should I Do?
Give yourself the best chance of avoiding delays by checking road conditions if driving, or bus and train timetables, amending your travel plans if necessary.
People cope better with power cuts when they have prepared for them in advance. It’s easy to do; consider gathering torches and batteries, a mobile phone power pack and other essential items.
If you are on the coast, stay safe during stormy weather by being aware of large waves. Even from the shore large breaking waves can sweep you off your feet and out to sea. Take care if walking near cliffs; know your route and keep dogs on a lead. In an emergency, call 999 and ask for the Coastguard.
Be prepared for weather warnings to change quickly: when a weather warning is issued, the Met Office recommends staying up to date with the weather forecast in your area.
