TT organisers say it's not looking promising for this evening's practice session.
The clerk of the course is monitoring weather forecasts, which point towards a wet and windy evening.
As a result, this evening's qualifying session, which hoped to have bikes away by 6.30pm - may not go ahead.
An update is expected at 3pm.
