The Steam Packet says two of today's sailings have been cancelled because of bad weather, with others possibly disrupted.
Among the first is this morning's Manxman crossing from Douglas to Heysham, which is due to set off an hour late at 9am on Monday, January 26.
Meanwhile the ferry's 1.45pm return from Lancashire has been cancelled, as has the 7.45pm sailing from the capital to Heysham.
The 2.15am journey from Heysham to Douglas is still listed as going ahead, but at risk - you can see the latest updates via the company's website.
