The three hour delay to the start of the Supersport 2 race has put back the schedule for the rest of today's action on the TT course.
The reorganised programme sees a practice session for XGP machines at 4pm, with the three lap Sidecar 2 race due to start at 6.15pm.
The usual 'access corridors' for vehicles will be open at a number of locations around the course, for one hour from 5pm.
Another practice session, for conventional machines, has been scheduled for 7.45pm, after the sidecar race has finished.
The Supersport 2 race saw a first TT win for Michael Dunlop, 32 years after his uncle Joey's first TT victory.
New Zealander Bruce Anstey was second and Conor Cummins from Ramsey managed his first podium finish, in third place.
