Storm Floris, named by the Met Office, is predicted to have "unseasonably strong winds". The amber warning covers a wide area from the central belt - including Glasgow and Edinburgh - to the Highlands. Gusts of up to 85mph are likely to hit exposed western coastlines and hills, while winds of 70mph are expected elsewhere.

Train operator LNER has warned passengers not to travel north of Newcastle due to Storm Floris, while Avanti West Coast has advised its customers not to travel north of Preston as it will be "heavily affected" by the weather.

A severe weather warning for Storm Floris - the UK's first named storm since Storm Éowyn wreaked havoc in late January - has been upgraded to amber amid forecasts of gusts likely to reach up to 90mph in Scotland.
