Storm Bert latest: Severe travel disruptions as ‘multi-hazard’ weather brings snow and flood risk

The Severn Bridge has been closed in both directions due to strong winds.

Road users in Gloucestershire are advised to use the M4 Prince of Wales Bridge as an alternate route, National Highways said.

Snow is falling across swathes of the UK, including in Edinburgh, Glasgow, Derbyshire and Northumberland.

Perth and Kinross Council cancelled its annual Perth Christmas lights switch-on event over safety and travel concerns.

An ambert weather warning covers parts of Angus, Perth and Kinross, Stirlingshire, Aberdeenshire and some of the Highlands, Argyll and Bute, the Borders, Dumfries and Galloway, East Ayrshire and South Lanarkshire.

Met Office meteorologist Aidan McGivern said Storm Bert’s arrival in the UK was following a “relatively quiet” night on Friday, with temperatures dropping to around -4C across parts of Scotland and -1C in eastern England.

“We’ll see two to four hours of heavy snow across parts of northern England and Scotland during Saturday morning,” Mr McGivern said.

“This snow will accumulate thick and fast, with five to 10cm at lower levels and as much as 20 to 40cm over hills accompanied by strong winds.

“You can expect blizzards over hills across northern England and Scotland, atrocious conditions for travelling and going over the hills and also the risk of power interruptions because of snow build up on power lines.

“So all in all, a multiple hazard event as we go into Saturday morning.”

British Airways has grounded 36 domestic and European flights to and from London Heathrow today. They include two round-trips to Glasgow, Manchester and Nice.

Swiss has cancelled two Zurich flights and one to Geneva.

Other airlines cancelling single flights at Heathrow include Aer Lingus to Dublin, Air France to Paris CDG and Lufthansa to Frankfurt.

The Independent is seeking confirmation from Heathrow airport and British Airways about the precise reason for the cancellations. When severe weather is forecast, the “flow rate” of arrivals at Heathrow is often reduced, triggering cancellations.

Loganair links from Glasgow to Tiree and Barra are grounded. The airline is offering any passengers booked to the Western Isles or the Isle of Man today the chance to re-book on another day within the next week.

Met Office meteorologist Aidan McGivern has said temperatures that will rise quickly as the storm brings with it milder air from the Atlantic, resulting in a “rapid thaw” by the afternoon.

“The melting snow and the heavy rain could lead to localised flooding in places but the wettest spots would be Wales, in the South West, particularly over south-facing hills, that’s where we’re likely to see gales and certainly the risk of impacts from wind as well as from rain,” the meteorologist said.

Over the weekend, Wales and the South West are at risk of seeing 75mm of rain widely, and potentially more than 100mm over the higher parts of South Wales and Dartmoor.

UK airports are so far not anticipating disruption as Storm Bert brings snow, heavy rain and strong winds to the UK.

A spokesperson for Birmingham Airport said: “Whilst we are not anticipating disruption at this time… we will continue to keep a close eye on the situation, as Storm Bert moves in.”

Manchester Airport said “we’re expecting bad weather but aren’t anticipating any disruption” while Newcastle Airport said it will be operating as normal overnight with teams “fully prepared to respond should conditions deteriorate”.

Caledonian MacBrayne ferries in western Scotland are heavily disrupted. The link from Oban to Coll and Tiree is cancelled all day “due to South Easterly winds gusting up to 57mph and swell conditions.” Ferries from Oban to Barra and from Mallaig to Skye.

P&O Ferries cancelled its early Saturday morning sailings between Cairnryan in Scotland and Larne in Northern Ireland. Stena Line’s Belfast to Cairnryan services are also disrupted.

On the English Channel, DFDS Ferries has cancelled ferries between Newhaven and Dieppe tonight and tomorrow.

The UK’s only hovercraft service, from Southsea to Ryde, is currently suspended.

Rail companies have urged passengers to avoid travelling to certain areas and some warned of reduced services while National Highways issued a “severe weather alert” for snow affecting Yorkshire and north-east England between 5am and 3pm on Saturday.

In Yorkshire, the A628 remained closed overnight in both directions between the A616 Hollingworth and the A57 Flouch due to snow, National Highways announced.

The A66 Trans-Pennine route was closed between the A6 and the M6 (J40).

In Scotland, there will be speed restrictions on the West Highland Line, Highland Mainline, Stranraer line, Glasgow South Western Line, Far North Line, and West Coast Mainline between Carstairs and the border.

ScotRail has withdrawn services from Inverness to Elgin, Aberdeen to Inverurie, and Glasgow Queen Street to Oban while trains from Glasgow Central to Carlisle will terminate at Dumfries.

South Western Rail (SWR) asked passengers to only travel west of Basingstoke if their journeys are essential.

SWR announced services between Exeter and London Waterloo will start and finish at Basingstoke, that journey times will be longer between Salisbury and Exeter and between Bournemouth and Weymouth due to speed restrictions, and services across its network will start later than usual on Sunday and Monday because of safety inspections.

TransPennine Express “strongly” urged customers not to travel north of Carlisle on Saturday while Avanti West Coast advised passengers not to travel north of Preston – including Lancaster, Oxenholme, Penrith, Carlisle, Glasgow and Edinburgh.

Storm Bert is expected to bring around two to four hours of snow to affected areas on Saturday before a “rapid thaw”, the Met Office forecast on Friday.

The forecaster said that areas higher than 400m metres above sea level could see between 20 and 40cm of snow on Saturday, with 10 to 20cm in areas 200 metres above sea level, and 2 to 5cm in lower areas.
