The entire country is under a Status Yellow rain warning from Met Éireann, which has warned of flooding for tonight and tomorrow.
The alert will go into effect for the 26 counties on Monday at 3 am and last until 8 pm that day.
Overnight, there could be “heavy or thundery pulses of rain,” the forecaster has warned, and this could cause flooding in some areas.
A yellow gale warning will also be in place from midnight for Carnsore Point to Loop Head to Fair Head, as coastal areas look set for cyclonic winds which will “reach gale force 8 of higher”.
The recent cold snap is expected to last into the next week, with daily highs in the range of 7 to 12 degrees.
