Race organisers say today's planned action around the course will be delayed.
Roads had due to close around the course at 10am, before a solo warmup and sidecar shakedown followed by the superstock and supertwin races.
However, rain, hill fog and strong winds are forecast for this morning - meaning a delay to the schedule.
A further update is expected at midday.
UPDATE: Due to rain forecast this morning, the Clerk of the Course has confirmed a delay to today’s schedule. A further update will be issued at 12:00.
