The Isle of Man Steam Packet Company says some sailings could be cancelled today.
Forecasted high winds mean sailings are at risk of possible disruption.
Journeys affected are this evening's 7.15pm Manxman crossing from Douglas to Heysham, and her return at 1.45am on Saturday, January 24.
A final decision on the sailings will be given at 5.00pm today - you can stay up to date via the Steam Packet website.
