Lunchtime summary We’re pausing our coverage now. Here is a summary of the day’s developments so far": Up to 25cm of snow is forecast in parts of England and Wales on Thursday, as the Met Office issued weather alerts and warned of disruption to travel. Amber weather warnings for snow have been issued for parts of northern England and north Wales, while a mixture of yellow rain and snow warnings will be in force across the four nations, PA Media reports. The Met Office said strong and gusty easterly winds may lead to “some drifting in places”, and that 10-15cm of snow is expected quite widely across the warning area. A separate amber warning for snow and ice will be in place between 8am and 3pm on Thursday across north Wales and north-west Shropshire, with 20-25cm of snow forecast in areas above 200 metres. Flooding between Swindon and Chippenham has blocked some railway lines, with disruption expected until 2pm. As a result, trains running between these stations may be cancelled or delayed by up to 45 minutes. An amber weather warning means travel delays on roads are likely; public transport vehicles and cars could be stranded; power cuts are possible; and some rural communities could be cut off temporarily. In the area covered by the snow and ice warning, the Met Office said untreated pavements and cycle paths could be impassable, PA reports. Met Office meteorologist Amy Bokota said an easterly wind meant that places “inland and higher up” were likely to see the most snow. The train company ScotRail has warned passengers to take extra caution while travelling today. It tweeted: “A yellow Met Office weather warning is in place for snow and ice from 18:00 today, until 15:00 tomorrow. This covers southern Scotland, up to and including Perth and Dundee.

Chris Wood, from the AA, said: If you need to travel, reduce your speed to account for the conditions and leave plenty of space behind other vehicles, and try to use main roads where possible as these are more likely to have been gritted. Allow extra time as it’s likely your journey will take longer than usual, and ensure you have plenty of fuel or electrical charge if driving an electric vehicle. The cold snap is likely to affect vehicle breakdown levels, with faults such as flat batteries and wiper faults. An amber weather warning means travel delays on roads are likely; public transport vehicles and cars could be stranded; power cuts are possible; and some rural communities could be cut off temporarily.

Met Office meteorologist Amy Bokota said an easterly wind meant that places “inland and higher up” were likely to see the most snow. She said it was “unlikely” that significant levels of snow would be on the ground for days, but added it could lead to difficult driving conditions on Thursday. Bokota said: The snow could cause some pretty poor driving conditions for parts of the Pennines and Wales, particularly through the afternoon and early evening. The forecaster added that most places would see a return to milder conditions by the end of Thursday. She said: It will be quite a short-lived cold snap for much of the UK, but continuing on a little bit longer through parts of northern England and Scotland into the early hours of Friday and the start of the weekend. A yellow rain warning covering much of southern England and south-east Wales - including London and Cardiff - has been issued from 2am on Thursday to 6am on Friday, with 15-25mm likely and up to 45mm on higher routes.
