Slots to be used Thursday and Friday
Afternoon qualifying sessions for the Classic TT and Manx Grand Prix will be used today and tomorrow.
Clerk of the Course Gary Thompson has confirmed the decision, following last night's curtailed session.
A crash on the Mountain Road before the roads closed meant the first part of it couldn't take place.
That came after Monday and Tuesday's ones were called off because of the weather.
This afternoon, all roads around the course will be closed between 12.30pm and 4.30pm, in addition to between 6pm and 9pm this evening.
