New potential start time of 1pm
The clerk of the TT course has confirmed a delay to today's schedule.
The Mountain Road was due to close at 9am, with the rest of the course following suit by 10am - for a 10:30am start.
However, roads will now begin to close no earlier than 11:45am instead.
Gary Thompson says it's due to the 'current conditions and the latest forecast'.
The new potential start time for today's qualifying sessions is 1pm.
A further update is expected by 11am; we'll bring you the latest as soon as we have it.
