Storm Hector has hit Britain with winds of up to 100mph causing damage to buildings, flying debris and fallen trees, as the Met Office issue danger to life warning.
Forecasters have upgraded weather warnings ahead of the storm, with an amber alert for wind in Northern Ireland and a yellow warning across Scotland and parts of England.
The Met Office said injuries and a danger to life is likely in coastal areas in Northern Ireland, with the chance of large waves and potential for beach debris to end up on roads, sea fronts and properties.
The first of the winds have already hit parts of Ireland and Cairngorms in Scotland this morning.
People have been advised to take care during rush hour with potential disruption due to fallen trees and the possibility that outdoor summer furniture will have been blown around overnight.
Humberside Police said a 40mph speed restriction had been placed on the Ouse Bridge in Goole due to the weather.
The storm, bringing wet as well as windy weather, is expected to move across Scotland and the north of England throughout the morning, and the yellow warning remains in place until 3pm.
The Met Office said: The strongest winds will reach the west coast during the early hours of Thursday before spreading eastwards during the day.
Westerly winds are likely to gust between 50 and 60mph in many areas and possibly around 70mph in some exposed locations. Winds should gradually ease from the west during Thursday afternoon.
In addition, a spell of heavy rain will accompany the wind with the highest rainfall totals over parts of western Scotland.
Such stormy weather is quite unusual for this time of year forecaster Luke Miall said.
The worst of the weather is going to be in the morning rush hour for most people. The storm is likely to clear to the north east around lunchtime or just after 1pm.
