Thundery downpours and flooding are in store for parts of Ireland on Friday.
Met Eireann has issued a Status Yellow rainfall warning as up to 40mm is expected to fall in the north west.
Cavan, Monaghan, Donegal, Longford, Westmeath and all of Connacht have been hit with the caution. The warming will be valid for 12 hours, between 8am and 8pm.
A Met Eireann spokeswoman said: "Rain followed by heavy, possibly thundery downpours could lead to accumulations of 25 to 40 mm with the risk of localised flooding."
The national forecaster is predicting widespread showers on Friday morning.
Some areas will be hit with thunderstorms in the afternoon which may lead to localized flooding.
However, parts of the south will experience brighter conditions with temperatures as high as 22C being forecast.
A forecaster said: "Rain will become widespread Friday morning. The rain heavy at times with some localised spot flooding and thundery downpours.
"Brighter conditions with showers will follow into southern areas by afternoon and extend north eastwards through the course of the day.
"The showers will be heavy with further thunderstorms developing in many areas leading to localized flooding. Top temperatures of 18 to 22 degrees generally, but 16 or 17 degrees in the north and northwest.
"Moderate southeasterly winds will veer southwesterly as the rain clears and increase fresh to strong and gusty over Munster and Leinster during the afternoon."
