The Great Storm of 1987 was one of the most damaging extratropical cyclones to affect southern England in the modern observation era. It struck on the night of 15 to 16 October 1987, bringing hurricane-force winds that caused widespread tree damage, transport disruption, and structural harm across the UK.
Although forecasts had indicated severe weather, the storm’s precise intensity and track were underestimated, leading to significant operational and public safety challenges in the immediate aftermath.

Meteorological Development and Forecasting Challenges
Evolution of the Extratropical Cyclone
This storm developed as a secondary low embedded within a larger weather system, rapidly deepening while moving southeast across the Bay of Biscay. The interaction between cold continental air and warm Atlantic moisture created a very steep pressure gradient, enabling hurricane-force gusts well inland, which is unusual for England.
Operational Forecasting Issues
Many forecast models in the 1980s struggled with the precise timing and intensity of such explosively deepening cyclones. Public warnings were issued, but the expected track shifted eastward, increasing the impact on regions that were less prepared for such severe wind events overnight.
Damage and Infrastructure Impact Across Southern England
Widespread Forest and Woodland Destruction
An estimated 15 million trees were felled or severely damaged, particularly in ancient woodlands and managed forests. The loss of canopy cover had long-term ecological and microclimatic effects, altering habitats and increasing surface runoff risks in subsequent winters.
Transport and Utility Disruption
Rail services were suspended for many days, major roads remained closed due to debris, and power outages affected hundreds of thousands of homes. The combined damage to infrastructure highlighted the vulnerability of interdependent networks to extreme wind events.
Emergency Response and Public Safety Measures
Initial Response and Resource Mobilization
Local authorities and emergency services coordinated large-scale clearing operations, supported by the military in some areas. Public safety campaigns emphasized the importance of avoiding travel and checking on vulnerable neighbors in the immediate aftermath.
Learning and Policy Adjustments
The storm prompted reviews of warning systems, public communication strategies, and forest management practices. Subsequent investment in forecasting capability and infrastructure hardening aimed to reduce similar risks in future extratropical storms.
Environmental and Long-Term Ecological Consequences
Habitat Change and Species Impact
The widespread loss of mature trees created open habitats that benefited certain bird species and early-successional plants, but also increased vulnerability to soil erosion. Woodlands required decades to recover structurally, affecting biodiversity patterns well into the 21st century.
Landscape and Land Management Shifts
Forestry policies evolved to favor greater species diversity and more resilient design, reducing the proportion of single-species blocks that could be devastated by a single storm event. These changes influenced regional land management practices for conservation and commercial forestry alike.
Key Takeaways and Recommendations for Future Storm Preparedness
- Rapidly deepening extratropical cyclones can produce hurricane-force winds far inland.
- Investment in high-resolution forecasting and public communication reduces harm.
- Diversifying forest structure increases resilience to large-scale windthrow.
- Coordinated emergency planning and prepositioned resources accelerate recovery.
FAQ
Reader questions
Why was the forecast accuracy so limited for the Great Storm of 1987?
Forecast models in the 1980s had limited resolution and data assimilation capabilities, making it difficult to predict the rapid intensification and precise track of the storm, which led to an underestimation of the risk for southern England.
How many people died in the UK during this storm event?
The Great Storm of 1987 resulted in 22 fatalities across the United Kingdom, with the majority occurring due to falling trees and associated accidents rather than direct wind exposure in buildings.
What immediate actions were taken by authorities once the storm passed?
Emergency services coordinated large-scale clearance operations, the military assisted with debris removal, and utilities worked to restore power and transport links, while public advisories discouraged non-essential travel.
Did this storm lead to long-term changes in forecasting or forest management?
Yes, the storm prompted substantial investment in meteorological capability and a reevaluation of forest management, leading to more diverse woodlands and improved public warning systems for future extreme weather events.
