Valentia Observatory in Co Kerry has recorded its highest level of rainfall on a single day since records began there over 150 years ago.
There was 105.5mm of rain in 24 hours.
Last night's torrential rain led to the closure of a number of roads on the south Kerry peninsula.
A significant land slippage blocked part of the Wild Atlantic Way tourist route between Baile an Sceilg and Portmagee.
A number of houses in the fishing village of Portmagee were badly damaged when flood waters entered during the night.
New rainfall record at Valentia observatory. 105.5mm in 24hrs. Highest since records began over 150 yrs ago!
