Met Éireann has issued a weather advisory for Ireland, warning that weather conditions will turn “increasingly wintry” from mid-week onwards.

Issued by the national meteorological office at 2:00pm today (Tuesday, January 19), the advisory will be valid from 12:00am tonight through to 11:59pm on Sunday, January 24.

During this time period, Met Éireann warns that it will “turn colder from Wednesday [tomorrow] with weather conditions becoming increasingly wintry for the rest of the week”.

There will be a risk of frost and icy conditions, with falls of sleet or snow at times.

Meanwhile, the meteorological office also issued a Status Yellow rainfall warning for Co. Donegal.

Issued at 11:00am this morning, the warning came into effect immediately and will remain in place until 9:00pm tonight.

It was highlighted that, in the county, heavy rainfall will lead to accumulations of up to 30mm, with higher accumulations in mountainous areas.

This will bring a risk of some river and localised flooding, Met Éireann warned.

A Status Yellow rainfall warning remains in place for counties: Galway; Roscommon; Mayo; Sligo; Leitrim; Longford; Louth; Westmeath; Meath; Cavan; and Monaghan.

Issued on Sunday, this warning will expire at 9:00pm tonight.

Finally, a Yellow rain warning is in place for all six counties in Northern Ireland. Issued by the UK Met Office yesterday, the alert came into effect at midnight and will remain in place until 12:00pm tomorrow.
