Weather having big impact on event
Changes to qualifying criteria for racers may be necessary, following a dismal start to this year's Festival of Motorcycling.
Saturday's practice was called off due to visibility being too bad for the helicopters, Monday's session was curtailed by a red flag incident in Ramsey, then Tuesday night's session also fell foul of the weather.
Clerk of the Course Phil Taubman says with a forecast that's far from certain for Wednesday evening's session, organisers may have to consider making some changes:
Warning over flare disposal after amenity site fire
Drug-driver jailed after passenger injured in crash
Suspended sentence for 56-year-old in cannabis supply case
Owner of a block of flats fined for failing to meet fire safety regulations
