Met Éireann has put Ireland on notice of wintry weather featuring snow, sleet, frost and ice due to blast of polar air which is due to sweep down over Ireland this week and lasting through the weekend at least.

The forecaster issued Weather Advisory for Ireland on Tuesday, January 19 for cold weather to set in from Wednesday.

The advisor says it will turn colder from Wednesday with weather conditions becoming increasingly wintry for the rest of the week. It says there will be a risk of frost and icy conditions, with falls of sleet or snow at times.

The advisory is valid from the early hours of Wednesday, January 20 to midnight Sunday, January 24.

Met Éireann says Weather Advisories are issued up to about a week ahead to provide early information on potentially hazardous weather. 

The origin of the cold weather lies in a so-called sudden stratospheric event which happened in 2018 when similar conditions led to the Beast from the East and Strom Emma. It is uncertain whether the 2021 version will lead to similar severe conditions.

Met Éireann has also outlined what conditions to expect in the coming days in its forecast to the weekend. The summary says it will turn colder for the rest of the week with widespread frosts at nights. There will be showers of rain, sleet and hail but good sunny spells also. MORE DETAILS BELOW TWEETS.
