Flooding and snow closes Isle of Man roads
The Mountain Road is one of a number of roads closed owing to snow and localised flooding in the Isle of Man.
The road will remain shut between the Ramsey hairpin and the Creg-ny-Baa until 08:00 GMT Thursday.
With heavy rain forecast well into the evening the island's Met Office has issued a level two flood warning across the island.
A comprehensive list of road closures is available on the Isle of Man Constabulary Facebook page.
Police have advised motorists to "watch out for standing water and drive with care".
