The Steam Packet Company says six Manxman sailings on Monday and Tuesday are at risk of disruption because of bad weather.
Predictions of gale force winds mean a decision will be made by 7am on Monday about the Douglas to Heysham trip at 8.45am and return voyage at 2.15pm.
The vessel's master will make a final decision about Monday's 7.45pm Douglas to Heysham crossing and 2.15am return by 5.30pm on Monday.
Meanwhile, a decision about Tuesday's Douglas to Hesham trip setting off at 8.45am and the return leg at 2.15pm is expected by 7am on Tuesday.
