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.

Ross Moran, Network Rail Scotland’s route director, said: “Storm Floris has caused significant disruption to Scotland’s railway, with wind speeds of up to 90mph, unprecedented for a summer storm. “Our teams have been working tirelessly to keep services moving where possible and to clear fallen trees and debris from the tracks.
