A number of Condor sailings have been cancelled between Thursday and Saturday due to Storm Gareth.
Thursday's Clipper and Friday and Saturday's Liberation trips are off because of the impending stormy conditions.
Another Liberation sailing has been added to Sunday's schedule.
Passengers that are due to travel on any of the cancelled sailings can join the next available service or cancel with a full refund.
Condor says it's sorry for any inconvenience the weather disruption may cause to travel plans.
