Met Éireann has issued a weather warning for the whole of Ireland, with heavy rainfall expected across the country until tomorrow morning.
A status yellow warning came into effect at 7pm this evening and will remain in place until 7am tomorrow morning.
Met Éireann has said accumulations of 25-40mm will occur over a relatively short time period and spot flooding is possible in some areas.
It said the rain will possibly lead to localised surface flooding, with some thundery bursts.
It added that there will be strong winds overnight, which could reach gale force on northern coasts by the morning.
Tomorrow morning will see brighter conditions, but showers will follow through the day.
Many of the showers will be heavy and prolonged with thunderstorms and the risk of hail.
Met Éireann said local downpours could potentially lead to hazardous driving conditions and flash flooding.
