High winds are forcing flights into Dublin and Cork airports to divert to other airfields, writes Patrick Flynn.
Met Éireann has two weather warnings as Storm Barbara sweeps across Ireland.
Winds at Dublin and Cork are already reported to have gusted up to over 85 kilometres an hour.
Aircraft on approach to Dublin are being advised to expect a holding time of at least 30 minutes – however some crews who had been holding for some time have already diverted to other airports.
Some flight delays @DublinAirport due to high winds, weather expected to improve in the afternoon. Check with your airline for latest info.
