The Steam Packet says its sailings tomorrow could be affected by severe gale force winds.
The company expects the 7.30am fastcraft sailing to Liverpool, and the return service at 11.15am to be cancelled.
The morning sailing of the Ben my Chree to Heysham at 8.45, and the return service at 2.15pm could be similarly affected.
Passengers are being reminded they can amend their bookings if they wish to do so.
