Storm Austen is currently developing in the Atlantic and is expected to deepen as it moves close to south-west England on Thursday night, with the strongest winds arriving early on Friday morning. The most severe conditions are forecast on coastal headlands in north and west Cornwall, where north-westerly gales could produce 80mph (130km/h) gusts, while 60 to 70mph gusts are possible elsewhere in the warning area, including inland.
The Met Office has warned of a high risk of significant disruption, including delays to road and rail transport, and possible effects on air and ferry services. Flying debris and large waves along the coast could cause injuries and danger to life, the warning says, while power cuts and damage to buildings are also possible.
A broader yellow wind warning covers large parts of southern England and south Wales, where some travel disruption is possible as the storm moves through.
