Festival of Motorcycling organisers say an update on today's practices will be made later this morning.
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.
