The Met Office has issued a yellow weather warning, covering all parts of Northern Ireland, saying strong winds are expected to cause some travel disruption on Thursday.
The weather warning is effective from 12:00am to 9:00pm on Thursday, 21st December.
A Met Office spokesperson said:
"Overnight Wednesday into Thursday, strong west to northwesterly winds are likely to develop across a large swathe of the country.
"Quite widely winds are expected to gust 45-55 mph, with stronger gusts, possibly reaching 65-70 mph, over and to the east of high ground, mainly across the north of the warning area. However, the strongest winds are likely to be across the far north and northeast of Scotland, including the Northern Isles during the morning.
"Here, gusts of 70-80 mph are possible for a time.
"The system has been named Storm Pia by the Danish Met Institute, as impacts are expected to be greater here.
"Winds will slowly moderate from the west Thursday evening."
