Met Éireann has said that conditions may be unsettled at times over the coming week with showers possible across the country.
Over the next seven days rainfall amounts are expected to increase with 1 to 2 times the average rainfall expected countrywide.
Temperatures will be normal for the time of year in the western half of the country while in the east it will remain warmer than average. Mean soil temperatures will continue to be above normal.
It comes as the national meteorological service said that yesterday (Sunday, May 19) was provisionally the warmest day of the year to date.
The highest temperature of 24.6°C was reported at the Met Éireann climate station located in Clonmel, Co. Tipperary.
Four other climate and synoptic weather stations saw the mercury climbed above 24° yesterday: Iniscarra, Co. Cork; Tulla, Co. Clare; Clareville, Co. Limerick and Athenry, Co. Galway.
There were also reports of flash floods and small landslides in parts of Co. Waterford yesterday due to thunderstorms.
Tributes were paid to a farmer in Cappoquin who helped to clear a road after 33mm of rain fell in a 20-minute period.
