Met Éireann has issued a 24-hour rain and thunderstorm warning for most of Ireland.
The status yellow weather warning for Connacht, Ulster, north Leinster and north Munster comes into effect at 9am this morning, and will remain in place until 9am on Saturday.
The alert affects 15 counties and comes as the UK Met Office has also issued a thunderstorm warning for Northern Ireland.
Met Éireann warned: “Thunderstorm activity with the risk of hail, coupled with longer spells of rain over Kerry, Limerick, Clare and Tipperary, will lead to localised flooding and hazardous driving conditions.”
Thundery outbreaks of rain today will bring hazardous driving conditions and spot flooding. ⛈️🚗
