Saturday's schedule will now feature additional qualifying sessions
This weekend's racing schedule has been updated by the clerk of the course.
Some racing has also moved to Monday (2 June), which was originally down as a rest day.
It's as poor weather is expected to hit the Island at points tomorrow.
The latest forecast from Ronaldsway Met Office states: "A dull and cloudy start to the day tomorrow with the risk of drizzle at first as well as extensive hill fog and some coastal mist in places.
"The cloud will gradually lift and break throughout the morning with some sunshine breaking through for a time before a spell of rain arrives from the west in the afternoon, clearing away early evening.
"The moderate to fresh southwest wind will increase fresh to strong as that rain arrives, best temperature of 15°C."
