The Steam Packet Company says two sailings have been called off, with another two in question today.
Today's 3pm Douglas to Liverpool crossing on the Manannan, along with her 7.15pm return, are cancelled.
Also in doubt are two Manxman sailings - the first her 8pm Douglas to Heysham trip along with her 2.15am return voyage.
