After consulting with Ronaldsway Met Office, officials say further information on todays afternoon and evening schedules will be made by 11.30am once conditions are reviewed.
As of now, a double-header of qualifying is planned with roads on the TT course closing between 12.30pm and 4.30pm, it's then due to re-open before shutting again between 6pm and 9pm.
Contingencies planned for today and tomorrow were announced earlier this week as poor weather has laid waste to several sessions since Saturday.
