Sailings this morning and this afternoon have been cancelled due to the expected arrival of Storm Dennis.
The Steam Packet Company has confirmed the 8.45am service to Heysham and its return originally planned for 2.15pm won't go ahead due to the poor weather which is forecast.
Meanwhile, the 8.30pm Ben-my-Chree voyage to the Lancashire port tonight faces delays or cancellation.
A final decision on that crossing will be made by 5.30pm this evening.
