The expected arrival of Storm Ellen means sailings tonight face possible disruption.
The Steam Packet Company says the 7.45pm Ben-my-Chree service to Heysham this evening and it's return at 2.15am tomorrow are in doubt due to the poor weather which is forecast.
The organisation says a final decision on both will be made by 6pm tonight.
Meanwhile, Manannan voyages to and from Liverpool tomorrow as well as crossings from the Island to Heysham on Friday are also facing possible delays or cancellation.
A decision on the Merseyside-bound journeys will be made by 6am tomorrow morning with a final verdict on the Ben crossings to Heysham to be made by 6.30am.
Full details are available on the Steam Packet Company website.
