The Met Office is "increasingly confident" the remnants of Hurricane Lorenzo will arrive in Derry and other parts of the North on Thursday.
Lorenzo will be an ex-hurricane by the times it reaches Derry.
On Monday, weather experts were reluctant to definitively say whether Lorenzo was moving towards the North of Ireland or not.
However, on Tuesday, Chief Meteorologist at the Met Office, Dan Suri, said he was "increasingly confident" Lorenzo would soon start making its way towards the North with places in the west bearing the brunt.
“There has been considerable uncertainty over the potential track of Lorenzo after it passes the Azores," said Mr. Suri.
"However we are now increasingly confident the remnants of Lorenzo will move towards the U.K., bringing a spell of wet and very windy weather to western parts on Thursday and Friday.
“At the moment the strongest winds are expected in western Ireland, with a risk of coastal gales developing in Northern Ireland and western Scotland on Thursday and Wales and south-west England on Friday."
Mr. Suri added: "Ex-Lorenzo will also bring spells of heavy rain to north-western parts of the U.K. through Thursday and Friday, particularly in Northern Ireland, western Scotland, central England and Wales.
“Our advice is to pay close attention to the weather forecast over the next couple of days and to keep an eye out for any weather warnings that may be issued in your area.”
