Authorities in Scotland have canceled trains and closed parks as a rare summer storm brings destructive winds to northern Britain.

An amber storm warning, covering much of mainland Scotland and the western islands, is now in force until 22:00.

Engineers are working to restore power to around 22,000 properties in the north and north-east of Scotland on Tuesday morning after Storm Floris hit the country with high winds. Work is also under way to clear trees from several railway lines which were blocked by the storm.
