A report into the flood which caused widespread damage in Co Cork a fortnight ago has been published by Cork County Council.
It noted that a striking feature of all three worst affected areas - Clonakilty, Douglas and Glanmire - was the short and steep nature of the catchment areas.
This, it says, combined with the already saturated ground conditions and the heavy rain on the night, was a major contributory factor to the flooding.
Rainfall figures across the county show a wide variety in the amounts that fell across from as much as 50mm in Douglas in Cork City to just over 10mm in Ballyvourney in mid-Cork.
The report states that two flood warnings were issued by Met Éireann at teatime on Wednesday, 27 June, warning of torrential and possibly thundery downpours of up to 70mm, leading perhaps to localised flooding.
The report says these warnings were passed on to the appropriate staff within the local authority, according to the Council's standard procedures and their flood response plan was activated at 4.09am on 28 June.
