Firefighters are tackling another fire at the derelict Harcourt Sands site in Ryde this evening (Wednesday).
Local residents alerted the fire service to smoke billowing into the sky at around 17:10.
Crews from Ryde are on scene and are dowsing the flames.
Smoke is choking the surrounding area.
It was just yesterday that 2 appliances were mobilised to the former holiday camp when a chalet was set alight. An appliance from Sandown was required to standby at Ryde to provide fire cover for the rest of the town.
Locals believe that youths are responsible for the incidents and are waiting for workmen to leave the site before gaining access.
