A status yellow rainfall warning has been issued for Cork.
Met Éireann is predicting an extremely wet start to the week in the Rebel county, with 25 to 35mm rain expected to fall, beginning in the early hours of Monday morning.
The rainfall warning, which also covers Kerry, is in place from 3am-4pm on Monday and forecasters have warned of a risk of spot flooding.
Meanwhile, Met Éireann is also keeping a close eye on Hurricane Lorenzo, which is currently just over 2000km southwest of the Azores but could track northeastwards towards Europe later in the week.
“The exact track and the intensity of Lorenzo as it transitions to an extratropical low is still very uncertain,” the forecasting service said today. "Met Éireann, the UK Met Office and the US National Hurricane Centre (NOAA) are holding daily conference discussions.
"The progress of Lorenzo and any potential impacts for Ireland are being closely monitored."
