"Unsettled" weather expected for much of the week as weather warning issued
According to weather forecasters the rain is set to be around for the next few days at the least.
A rain weather warning has been put in place for the Donegal area, with up to 32 mm of rainfall expected to fall in the next 24 hours.
Rain in Leinster, Connacht and Ulster will gradually clear northwards, but will continue all day in the northwest and north. This evening and tonight showery rain will become more widespread again.
The forecast comes after a wash-out for the majority of the Bank Holiday weekend.
Between 7am on Saturday and 7am on Sunday, experts said, an average of 23.8mm of rain fell over the entire country.
"This amounts to a total of about 2,009,219,800,000 - more than two trillion litres of water," said Feral Tierney from Irish Weather Online.
"That's 315,000 litres for each man, woman and child, or about two billion bathtubs."
