The Steam Packet says two sailings are cancelled today, while this morning's has been delayed.
The crossings not going ahead are the Manxman's 12.45pm journey from Heysham to Douglas, and her 6.45pm return to Lancashire.
Meanwhile this morning's 7.30am journey is now scheduled to set off at 8.30am instead, this Thursday, January 29.
The cancellations are because of forecast bad weather, with gale force winds predicted by Ronaldsway Met Office later today.
