Tonight's racing for the Festival of Motorcycling will go ahead, following an earlier course inspection.
Clerk of the course, Gary Thompson, says conditions have improved during the afternoon.
Race organisers added there is currently poor visibility between the Bungalow and Keppel Gate, but that is expected to clear before the roads close this evening.
The roads will shut at 6pm and re-open no later than 9pm.
Tonight's schedule is on our website.
