Driving in snow in UK

The 'Beast from the East' bites the UK

During the last week of February and into the first week of March 2018, the ‘Beast from the East’ reared its ugly head and brought severe winter weather to much of the UK in what was the coldest period for several years. The bitter winds drawn down from Siberia were caused by the Sudden Stratospheric Warming event that occurred several days previously.

Amber and Yellow National Severe Weather Warnings for snow, snow and wind, and snow and ice were issued for many regions as bands of snow showers moved across the UK from northern Scandinavia and northwest Russia. Parts of Scotland also had a red weather warning – the highest weather warning released by the Met Office.

Although there were regional differences, accumulations of 5-10cm occurred, with some northern and eastern areas seeing accumulations in excess of 20cm and even 50cm in some parts. Snow drifts were also prominent in the country due to the strong winds.

Some locations struggled to get above 0°C during the day, with night-time temperatures down to - 8 °C quite widely at times. A significant wind chill made it feel several degrees colder than thermometers show. The lowest temperatures occurred on 28 February and 1 March.

As a result of the severe weather, many roads became blocked up and down the country, causing motorists to become stranded. In addition, there were disruptions and cancellations on other transportation networks, school closures, interruptions to power supplies, and some remote communities were even cut off.

On 1 and 2 March, Storm Emma (named by the Portuguese weather service) moved up from the continent, bringing heavy snow, gusts of more than 60mph and freezing rain to southern parts of the UK. Freezing rain* starts as snow, ice, or hail, then melts as it falls through a relatively warmer layer before encountering colder air near the ground. As a result, the rain droplets become ‘supercooled’ and are below freezing on impact on surfaces such as roads, pavements and power cables.

The Met Office issued a red weather warning - the most severe alert - during the event across parts of Devon, Cornwall and Scotland. It was only the third such warning the Met Office has issued since the current system came into force in 2011. A red warning means: “Widespread damage, travel and power disruption and risk to life are likely”.
