Delays to racing could have a knock-on affect on the Red Arrows returning to the TT this evening.
The RAF display team is due over the capital from 7.30pm in one of the biggest attractions of the festival.
Roads around Douglas and Onchan Heads are expected to be busy as fans arrive to find a vantage point.
However, an update is due to be made at 3pm about the display as late racing could affect the airspace over the Island.
