The Steam Packet says four upcoming sailings are at risk of possible disruption because of bad weather.
The first is the 8am on Friday, January 23 from Douglas to Heysham, and the planned return at 1.45pm - the company says a final decision will be made at 6am tomorrow morning.
Meanwhile that evening's Manxman sailing from the capital to Heysham is also at risk, as is the return at 1.45am on Saturday, January 24.
Updates and more details of when the company will make a final decision on whether they're going ahead can be found on the Steam Packet website.
