Mountain Road restrictions to be in place, too
Sailings are in doubt for three days, with this morning's 8.45 one to Heysham - and therefore this afternoon's return - having been cancelled.
A decision on this evening's sailing and its overnight return will be made by 5.30pm.
Storm Ciara is expected to bring gales and severe gales to the Irish Sea today, tomorrow and Monday.
Meanwhile, between midday today and midday tomorrow no high-sided vehicles will be allowed on the Mountain Road between Barrule Park in Ramsey and the Creg-ny-Baa.
