Meteorologists are warning of a risk to life on Friday as Storm Éowyn batters the UK.
Very strong winds are forecast to strike the north of England.
Gusts of up to 90mph could cause power cuts, travel disruption and damage to buildings.
The Met Office has now issued an amber warning of wind from 6am to 9pm on Friday which covers most of North Yorkshire north of York.
York and Selby remain covered by a yellow warning of wind.
“Storm Éowyn is expected to bring very strong winds and widespread disruption on Friday,” a Met Office spokesman said.
“Power cuts are likely to occur, with the potential to affect other services, such as mobile phone coverage.
“Road, rail, air and ferry services are likely to be affected, with longer journey times and cancellations possible. Some roads and bridges will close.
“There is a chance that damage to buildings and homes could occur, with roofs blown off and power lines brought down.
“Injuries and danger to life could occur from flying debris, as well as large waves and beach material being thrown onto sea fronts, coastal roads and properties.”
Meteorologists said the strongest winds of up to 90mph were likely to be found along the more exposed coastal areas, while gusts are expected inland of between 60mph and 70mph.
The change to conditions is being caused by a powerful jet stream pushing low pressure across the Atlantic and towards the UK, following a recent cold spell over North America.
The forecaster advised securing loose items outside homes, including bins, garden furniture, trampolines and sheds, and gathering torches and batteries in case of any power cut.
Those travelling in this “disruptive spell of weather” are urged to be cautious, as road, rail, airports and ferries are likely to be affected.
Another area of low pressure could bring further wet and very windy weather across the UK by Sunday.
There is the potential for further weather warnings over the weekend and throughout next week, the Met Office added.
