Tuesday’s scheduled races, the Supertwins and Superstock events, were both postponed because of adverse weather, and will now take place on Wednesday at 11:45 BST and 14:00 BST respectively, both over three laps.
The second sidecar race of the week has been rescheduled from Wednesday to Thursday, with an 11:45 BST start time, with the Supersport race two due off at 14:00 BST.
The Supersport event has been reduced to a race distance of three laps instead of four.
All roads around the circuit will close at 10:00 on both days, with the Mountain Road closing an hour earlier.
A solo warm-up lap will take place on Wednesday and Thursday at 10:30.
The Supertwins race one was called off less than an hour before its start time of 19:40 BST on Tuesday because conditions around the circuit were deemed unsuitable.
After completing a warm-up lap a number of competitors expressed concern about lingering damp patches around the course following rain in the early part of the day.
