8 out of Met Éireann’s 24 synoptic weather stations have recorded more than half their average monthly rainfall in the first three days of October, with the west of the country worst affected.

At Mace Head in Galway, 70 per cent of the station’s October long-term average fell by Friday night. Almost three inches of rain (74.2mm) were logged in just 72 hours. Athenry also passed the halfway mark, with 66mm recorded compared with a long-term monthly average of 118mm.

Other stations to exceed half their monthly totals include Knock, Newport and Claremorris in Mayo, Markree in Sligo, Ballyhaise in Cavan and Mount Dillon in Roscommon.

The deluge followed two days of heavy rain as Storm Amy tracked to the northwest of the country, bringing excessive rainfall to parts of the west and north.

Rainfall has been above average across Ireland over the past week. Casement Aerodrome in Dublin recorded 26.2mm, or 161 per cent of its long-term average, while Claremorris in Mayo logged 107mm, more than four times its average weekly total.

The unsettled spell is expected to give way to drier weather. With high pressure set to dominate in the coming week, rainfall will trend well below normal. Parts of the south and southeast may record little or no measurable rain up to mid-month, according to Met Éireann.
