There's been a 30 minute delay to this afternoons festival of motorcycling practice.
Officials say its due to mist on the mountain road, and as a result roads around the TT course will now close at 1pm and are due to re-open at 4.30pm.
Meanwhile, the evening schedule is still due to go ahead as normal with the circuit shutting at 6pm and opening again no later than 9pm.
