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:
Steam Packet 'confident' in Manxman's November return
How will global oil prices impact Manx customers?
Auction opens for box seats at Samantha Barks candlelit concert
Chilli and BBQ festival postponed by 24 hours
