Met Éireann Advisory issued on Thursday afternoon:
A combination of a vigorous Atlantic weather system and the remnants of Hurricane Ophelia will pass close to
Ireland on Monday, and has the potential to be a high-impact event in parts of the country. There is a lot of
uncertainty as to the exact evolution and movement of this weather system during the coming four days, but
storm-force winds, outbreaks of heavy rain, and very high seas are threatened. Met Éireann will maintain a
close watch on the evolution and issue further advisories and warnings as these are warranted.
Saturday 14/10/17
Level Red for southwest & west (5 counties), orange for the rest of country.
Ex-hurricane Ophelia is expected to bring severe winds and stormy conditions on Monday. Mean wind speeds in excess of 80 km/h and gusts in excess of 130km/h are expected, potentially causing structural damage and disruption, with dangerous marine conditions due to high seas and potential flooding.
