The GFS sea-level pressure and wind speed (meters per second) forecast from the GFS is below and it shows the storm strengthening and broadening just southeast of Ireland, before weakening just a bit prior to landfall.
Nevertheless, the system is quite strong at landfall. The areas in yellow feature sustained winds of 28 m/s (56 knots) and orange around 35 m/s (70 knots), the latter are hurricane force. These areas are found over water. Winds are weaker over land, but still quite strong.
The Irish Meteorological Service, Met Éireann, has issued a National Weather Warning and is expecting sustained winds of 80 km/h (43 knots) and gusts in excess of 130 km/h (70 knots) in the southern half of the country.
