A nationwide Status Yellow weather warning has been issued by Met Éireann this morning.
The warning, issued at 10am this morning, states: "A rapidly deepening wave depression will track eastwards over northern parts of Ireland later Wednesday night and early on Thursday.
"It will bring a period of severe winds and heavy rain, with snow on northern hills.
"Strong to gale force southwest winds will develop overnight and become gale force northwesterly by Thursday morning with severe gusts, especially in northern and eastern areas."
The warning is valid from a minute past midnight on Thursday morning until 11am later that day.
Keeping an eye on this area of low pressure on Thursday. Potential for snow across Scotland & N England with gales for many. Alina pic.twitter.com/MtaB05s9cW— BBC Weather (@bbcweather) February 21, 2017
Storms with the potential to cause substantial impact are named by the British Met Office and Met Éireann, moving through the alphabet.
The first was named Abigail in November 2015, after members of the public suggested monikers for the Name Our Storms project.
The forecasters are now in their second run of the alphabet - after Doris, people can expect to hear of Storms Ewan, Fleur and Gabriel.
