Bus Vannin says a number of buses are unlikely to run this morning, with more problems covering services.
A lack of drivers and staff illness have led to more than a week of cancellations.
This morning, it says services between Douglas and Ramsey, Peel, Foxdale, Noble's Hospital, Onchan, Birch Hill and Ballachrink all face being called off.
On Facebook, it says it'll update people throughout the day.
