A yellow weather warning remains in place this morning for ice.
The warning, which runs until 10am, affects the whole Island but most at risk are areas above 500 feet as well as more sheltered low-lying areas.
The Mountain Road reopened yesterday afternoon but the Tholt y Will and Beinn Y Phott roads are still shut.
Motorists are being advised to drive carefully over the mountain as conditions may still be slippery in places.
