The Beast from the East – 2018 Cold Wave Explained

In late February 2018, a severe cold wave swept across the British Isles, bringing extreme snowfall, sub-zero temperatures, and widespread disruption. The event became widely known as the Beast from the East—a name that captured both its severity and its origin in frigid Siberian air. The cold spell coincided with Storm Emma, amplifying its impact across the United Kingdom and Ireland.

Anticyclone Hartmut served as the driving force behind the weather system. Unusually for a high-pressure system, it formed as an anticyclonic storm, drawing polar continental air from Siberia eastward across the North Sea. This collision of air masses created conditions for heavy snowfall and dangerous freezing conditions that persisted for nearly two weeks. Authorities issued rare red warnings, signaling risks to life across multiple regions.

The event left a lasting impression on both nations. Ireland experienced its worst winter weather in over three decades, while the United Kingdom saw 17 fatalities over the course of the cold wave. Infrastructure across both countries suffered significant disruption, with airports closed, rail services halted, and thousands left without power. Understanding the Beast from the East helps communities better prepare for similar extreme weather events in the future.

What Was the Beast from the East Storm?

The Beast from the East refers to a severe cold wave that affected the British Isles between late February and early March 2018. The event was characterized by an extended period of heavy snowfall, freezing temperatures, and dangerous wind chills. Meteorologists linked the phenomenon to a complex interaction between atmospheric pressure systems that drew exceptionally cold air from Siberia across northern Europe.

The cold wave arrived in two distinct phases. First, the Beast from the East pushed frigid air from Scandinavia eastward into the British Isles. Then, Storm Emma—named by the Portuguese meteorological service—moved northward from the Azores, colliding with the established cold air mass. This collision created ideal conditions for heavy snowfall, blizzard conditions, and freezing rain across large areas.

Where Did the Beast from the East Affect?

The Beast from the East impacted both the United Kingdom and Ireland, though the severity and character of the effects varied between the two nations and across different regions within each country. The combination of heavy snowfall, freezing temperatures, and strong winds created dangerous conditions throughout the British Isles.

United Kingdom Impacts

Across the United Kingdom, the Beast from the East brought extreme winter conditions rarely experienced in that region. The Met Office issued its highest-level red snow warnings, indicating a risk to life from the severe conditions. Heavy snowfall blanketed much of England and Wales, with the most significant accumulations occurring in elevated areas of southwest England and southern Wales.

Transportation networks bore the brunt of the disruption. Several major airports suspended operations, including Heathrow and Gatwick, due to snow and frozen runways. Rail services experienced widespread cancellations and delays, with some services stranded for extended periods. The Wikipedia record of the 2018 cold wave documents trains stuck on tracks for up to 14 hours as signaling equipment failed and tracks became blocked by drifts.

• Heathrow and Gatwick airports temporarily closed
• Rail services suspended across multiple operators
• Power cuts affected thousands of homes
• Schools closed across England, Wales, and Scotland
• Road closures on major motorways due to abandoned vehicles

Ireland Impacts

For Ireland, the Beast from the East represented the most severe winter weather event in more than 30 years. Met Éireann, the Irish meteorological service, coordinated closely with emergency responders as conditions deteriorated rapidly. The southern and eastern regions experienced the heaviest snowfall, with accumulations reaching up to 50 centimetres in some elevated areas.

When Storm Emma arrived on March 1, conditions became particularly dangerous. The combination of freezing rain and strong winds created treacherous ice-covered surfaces across roads and footpaths. Dublin and other major cities saw widespread travel disruption, with many commuters stranded overnight. Hospital emergency departments reported increased attendances for weather-related injuries including falls on ice and hypothermia cases.

Comparative Impacts Summary

Where Did the Beast from the East Come From?

The Beast from the East originated in Siberia, where an enormous mass of frigid continental polar air had been building for weeks. This Arctic airmass extended from the Russian Far East across Asia and Europe, creating the foundational cold source for the event. The system that eventually brought this cold air westward into the British Isles took shape over Scandinavia, where Anticyclone Hartmut established itself as an unusual and powerful high-pressure system.

Meteorological Origins

Anticyclone Hartmut differed from typical high-pressure systems in both its structure and behavior. Rather than the more common low-pressure storms that affect Atlantic-facing nations, Hartmut formed as a rare anticyclonic storm—a high-pressure system that nonetheless carried hurricane-force winds near its core. According to Royal Meteorological Society analysis, this configuration allowed extremely cold air to be funneled eastward rather than spreading outward as high pressure typically does.

The underlying driver of this atmospheric configuration was a sudden stratospheric warming event. When the stratosphere warms rapidly, it disrupts the polar vortex—the ring of cold air circling the Arctic. This disruption weakened the jet stream, allowing the normal west-to-east progression of Atlantic weather systems to stall. With the polar vortex displaced, winds shifted to draw continental polar air directly from Siberia toward western Europe.

• Siberian source air initially reached approximately -50°C
• Anticyclone Hartmut centered over Scandinavia
• Sudden stratospheric warming weakened the polar vortex
• Jet stream disruption redirected air masses
• Air picked up moisture crossing the North Sea

The Role of Storm Emma

Storm Emma arrived from the south as the Beast from the East held its grip on the British Isles. Named by the Portuguese meteorological service, European windstorm Emma would have brought wet and windy conditions on its own. However, its collision with the established cold air mass transformed what might have been merely uncomfortable weather into a dangerous snowstorm.

When warm, moist Atlantic air from Storm Emma met the sub-zero continental air, the result was intense snowfall and freezing rain. This atmospheric clash produced blizzard conditions with visibility near zero in some areas. The combination of fresh snow accumulation and strong winds led to significant snow drifts, compounding the transport disruption already affecting the region.

The Beast from the East in Context

The Beast from the East stands as a reminder of the British Isles’ vulnerability to extreme winter weather, despite the region’s generally mild maritime climate. Most winters, the Atlantic jet stream brings changeable but relatively mild conditions from the west. The Beast from the East represented nearly the opposite—an prolonged incursion of continental polar air that bypassed the moderating influence of the ocean.

This pattern differs significantly from the typical winter storms that affect the region, such as the European windstorms more commonly experienced. Where Atlantic storms bring mild, wet weather, the Beast from the East brought extended cold, dry air and heavy snowfall. The rarity of this pattern explains why infrastructure and communities were less prepared for its impacts than they might be for more common winter hazards.

The event also highlighted the value of stratospheric monitoring for weather forecasting. Meteorologists identified warning signs weeks before the cold wave reached the British Isles, demonstrating that understanding upper-atmosphere dynamics can improve prediction of extreme surface events. This knowledge continues to inform forecasting practices and emergency preparedness planning.
