Met Éireann has issued a weather warning for all counties ahead of a bout of stormy weather heads towards Ireland and snow is also possible in parts with one of its forecasters saying cold weather could bring 'wintry' showers later this week.

The Status Yellow wind warning says it will become very windy from Wednesday afternoon through until Thursday morning.

The alert says southwest winds will veer westerly gust at 90 to 110km/h generally, higher at times on hills and coasts in the south and west with a risk of some wave overtopping.

The alert is valid from noon Wednesday to 7am Thursday, March 10 - 11. More below picture.

The forecaster has also issued a commentary on what to expect through the week.

It says that after a quiet start to meteorological spring, conditions will turn much more unsettled this week with spells of wet and very windy weather on the way. 

It says high pressure has brought largely dry and settled weather since the start of March, but as the jet stream moves over Ireland in the next few days this will steer a succession of Atlantic low-pressure systems towards us.

Met Éireann meteorologist, Paul Downes, said Monday was the last day of the settled weather with wet and windy weather expected through the rest of the week.

“Rain and strong winds will push east across the country from Tuesday afternoon, becoming widespread by early evening.  Further wet and very windy weather is expected on Wednesday as a deep low-pressure system tracks to the northwest of Ireland – bringing very strong south-westerly winds and spells of heavy rain through Wednesday afternoon and Wednesday night.

“During the early hours of Thursday, this low-pressure system will clear away from Ireland, introducing a colder and more unstable airmass.  However, it will remain very windy into the weekend along with blustery showers, these possibly turning wintry over high ground,”

Met Éireann forecast charts show that by Friday, March 12 a cooler polar maritime airmass will settle over the UK & Ireland.
