The main trunk water main serving Tralee and Castleisland burst at Farranfore overnight which is affecting water supply to customers in many parts of Tralee, Farranfore and Castleisland.
Kerry County Council staff are working to restore the supply as soon as possible.
Due to the burst main, there are works on the main road through Farranfore village at present.
As a result motorists may experience delays and are asked to use alternative routes if possible.
Kerry Airport are asking those intending to fly today to leave a little earlier to allow for the traffic delays.
