The forecast has already prompted Irish Rail to reschedule works on bridge and coastal defence which were dure along Dart lines this weekend.
The maintenance works between Dún Laoghaire and Greystones, which had been due on Saturday and Sunday, have been cancelled as high winds forecast in the area threaten to impact the safety of the proposed works due to the bridge lift involved, as well as work on exposed terrain on Bray Head.
As a result of the cancellation, full Dart and Dublin to Rosslare Europort services will now operate across the weekend. The works have been rescheduled to the weekend of November 1st and 2nd.
Other works scheduled across the rail network in other parts of the country are proceeding, however.
