Met Office predicting showers and wet roads this afternoon
Today's TT Practice has been moved to an evening session.
Organisers have made the decision due to the 'high probability' of showers and wet roads during this afternoon.
As a result, roads around the course will now shut at 6pm tonight.
After that, the superbike, superstock and supersport machines will start the revised schedule at 6.20pm.
That will be followed by the supersport and supertwin classes at 7.25pm.
Finally, the sidecar qualifying will then round off the schedule from 8.05pm.
Roads are scheduled to re-open no later than 9.30pm this evening.
