A Met Office yellow severe weather warning for wind will come into force in Northern Ireland from 16:00 BST Friday to 06:00 Saturday.
Additionally across Scotland, parts of north-west England and North Wales a yellow severe weather warning for wind will come into force from 18:00 BST on Friday until 23:59 on Saturday.
Widespread gusts of 50-60mph (80 – 96 km/h) will be likely within the warning area but may reach up to 70mph (113 km/h) in some places for a time.
Exposed coasts and hills in northern and western Scotland could experience gusts as high as 80mph (129 km/h).
These will be damaging winds which could blow trees over. As many trees are still in full leaf, they are more likely to be toppled with branches broken off than during the winter when the wind can whistle through them unimpeded.
Power cuts are possible.
There will also be transport disruption, particularly across Scotland with the possibility of cancelled ferries and restrictions on the road and rail network.
Flights from Scottish airports may also be delayed or cancelled.
The most destructive winds will ease during Saturday morning but it will remain very windy through the day.
Gusts of 60-70mph (97-113 km/h) will be felt in northern and western Scotland. Across the UK, gusts will widely be up to 40-55mph (64 – 89 km/h).
Even these lower wind speeds have the potential to bring further disruption during Saturday.
