There delays for drivers heading in and out of Sandown, towards Ryde, this morning (Wednesday).
Flooding on Morton Common is being blamed for disruption.
Traffic is said to be slow-moving due to surface water on the road.
Water levels are 'rising', according to Southern Vectis.
The bus operator's 2, 3 and The Downs Breezer will divert, as a result.
Avenue Road and Devonia in Sandown won't be served.
