Met Éireann said that the coming week will bring rainfall of between 30 and 60mm, totals may be as high as 70mm in the south and east.
This is around 2 to 3 times the average rainfall for this time of year, with over 4 times the average rainfall possible in parts of the south and east this week.
Although mean soil temperatures will drop, they are still several degrees above average.
There will be limited drying conditions over the coming days with a lot of rain expected.
The best drying conditions and opportunities for spraying will be on Saturday.
Soil conditions will steadily deteriorate over the coming days with most soils likely becoming saturated, and potential for moderate and poorly drained soils becoming waterlogged.
A potato blight advisory is in effect until Saturday morning, another advisory is due to run from Sunday evening until Monday evening as weather conditions conductive to the spread of the disease will affect all regions.
