Flood rainfall was well short of record.

The report said that rain began to fall around midnight on June 8 across Ceredigion. The highest totals were recorded on the western upslopes of the Cambrian Mountains immediately east of Aberystwyth as moist air was lifted over the Plynlimon massif.

Daily rainfall totals at low elevation sites were "unremarkable", typically less than 50 mm (Bow Street, Frongoch and Gogerddan), but increased significantly at sites above 180m in the Rheidol and Leri catchments (Dinas, Bontgoch and Pwllpeiran).

The second heavy "pulse" of rainfall in the Leri headwaters was critical in causing flash flooding in the early hours of Saturday, June 9 as soils in the catchment were saturated and hillslope runoff very rapid.
