Weather warnings upgraded as Storm Doris forecast to bring winds up to 80mph
Drivers are urged to consider changing their plans ahead of Storm Doris' arrival as Highways England has issued a major weather alert on major roads, with gusts expected to reach 70mph on some routes.
Weather warnings have also been upgraded with heavy snow and winds of up to 80mph forecast.
Storm Doris is likely to cause travel disruption, damage buildings and send debris flying when it hits on Thursday morning, the Met Office has warned.
Particularly at risk are high-sided vehicles, caravans and motorbikes. Drivers are "strongly advised" to avoid travelling on some stretches of road in Yorkshire, the Midlands, and the east and north-west of England.
Richard Leonard, Head of Road Safety at Highways England, said: "We're expecting Storm Doris to have a significant impact on the roads throughout the day tomorrow so are urging drivers to consider changing their plans if necessary and to slow down in stormy weather.
"Drivers should look out for warnings on the electronic message signs and listen for updates in radio travel bulletins."
Amber warnings predict strong winds and heavy rain in parts of North Wales, the Midlands, and east and north-west England, while winds as fast as 60mph are also expected to batter southern England.
Meanwhile, up to 15cm of snow could fall across parts of Scotland and north-east England in treacherous, blizzard-like conditions.
Weather warnings have been upgraded to amber across Scotland's central belt, the Borders, Dumfries and Galloway, Tayside and Fife.
"We have got a fairly active area of low pressure coming in from the Atlantic," said Met Office forecaster Emma Sharples.
"It is strengthening as it moves eastwards to the UK."
The Met Office's amber weather warning alerts people that "whilst the strongest winds look to be only short-lived, damage to structures, interruptions to power supplies and widespread disruption to travel networks are likely, with a danger of injury from flying debris".
Storm Doris is expected to move on quickly, with the worst of the weather gone by Thursday evening.
While further Atlantic gusts will bring more rain and wind through the weekend and into next week, they are not expected to reach the heights of Doris.
AA spokesman John Snowling said: "The unpleasant combination of torrential rain, severe gales and heavy snow will create some very poor driving conditions, with the potential for roads to be affected by black ice, debris or standing water.
"Wind can also bring down tree branches, blow you off course or blow other vehicles into your path.
"Expect travel disruption as some roads will be treacherous."
Anyone affected by power cuts during the storm is encouraged to dial 105 for further information.
Storm Doris's appearance contrasts with Monday's temperatures, where visitors to Kew Gardens, west London, enjoyed the warmest day of the winter so far, at 18.3C (64.9F).
Parts of London and the south of England had temperatures warmer than Ibiza, southern Spain and Menorca.
