Meanwhile, Met Éireann said that rainfall amounts varied across the country over the past week.

Conditions were drier in other parts with just 3.1mm of rain recorded in Malin Head (13% of the average).
For the coming week, the weather is expected to be unsettled with rain and drizzle, meaning that rainfall amounts are anticipated to be above normal nationwide.
The highest falls are expected across the west and southwest where 80 to 100mm is possible.
Over the past seven days, temperatures were close to or slightly below normal for many areas, but just above average in the southwest. Mean values ranged from 3.3 to 8.1 °C.
Met Éireann said that it will be milder this week and as a result air temperatures are due to be 3 or 4° above normal.
Soil temperatures are currently generally near or above average, ranging between 3.6 and 6.9°.
Due to frequent spells of rain this week, drying conditions will generally be poor, while spraying opportunities will be limited.
Met Éireann said that all well and moderately drained soils are currently saturated or close to it, poorly drained soils are either saturated or waterlogged.
Spells of rain over the coming week will lead to further deterioration in soil conditions.
