Winds peak according to the ECMWF at around 117mph; this is oversea. But corresponds to a mid Catogary 3 hurricane level on safir simpson, though I should enphasise that this is not a hurricane, just a hurricane force extratropical cyclone.
In terms of strongest sustained winds over actual land, ECM has it at 72mph over parts of SW Ireland which is near Hurricane force, and at which time the storm itself has maximum winds of 101mph (or cat 2 equivalent).
Based on this I think its basically certain that SW ireland will see Beaufort9 'severe storm' force winds, and a coin toss somewhere could be in the Beafort10 'Hurricane' force winds catogary. Obviously this means I would expect the maximum gust recorded to be even higher and probably approaching 150mph. Its quite likely this will be a record breaker of sorts for somewhere.
