The fog is causing numerous travel problems today.
At the airport a number of flights have already been delayed or cancelled.
However passengers are still being advised to check in as normal and on time.
Last night the Ben-my-Chree was unable to dock at Heysham Port because of zero visibility meaning it was unable to unload and reload.
However this morning's sailing at 8.45am to Heysham is expected to depart and arrive as scheduled.
