Overview and Key Facts
On the night of 15–16 October 1987, a violent extratropical cyclone, often called the UK hurricane or the Great Storm of 1987, struck southern England and northern France with unusually intense winds for an October event. The storm caused 22 fatalities in the UK, widespread disruption to transport and utilities, and extensive deforestation that reshaped landscapes and urban environments. It remains one of the most significant severe wind events to affect southern England in the modern observational record. This article explains how the storm formed, how it was forecast, its direct and indirect impacts, the response and recovery efforts, and the long-term changes it prompted in weather monitoring and forest management.

How the Storm Developed
The storm originated from a disturbance over the Bay of Biscay on 13 October 1987. An intense upper-level low diving southeastward into a deep area of low pressure over the Bay of Biscay helped the surface low intensify rapidly. By 14 October, explosive cyclogenesis— a drop in central pressure of more than 24 mb in 24 hours— was underway. The system tracked across the Bay toward the English Channel, with a tight pressure gradient feeding strong southwesterly winds. While labeled a "hurricane" colloquially, it was an extratropical cyclone, distinguished by energy derived from temperature contrasts rather than warm ocean water. Nevertheless, the storm brought hurricane-force winds to coastal and inland areas, with gusts exceeding 100 mph in many locations.
Forecast and Warning Timeline
Forecast performance on 15 October 1987 illustrated both progress and limits of mid-1980s numerical weather prediction. Global models initially indicated a vigorous Atlantic low, but the precise track and rate of intensification near the UK were uncertain. Some ensemble and model solutions hinted at a stronger than average sting jet—a narrow descending airstream that can produce localized wind gusts far in excess of the broader storm— but this concept was not yet widely used operationally. Public warnings were issued, yet some locations experienced significantly higher winds than were explicitly forecast for inland sites. The event highlighted gaps in representing rapid intensification and sting-jet dynamics in operational models, leading to subsequent research and model improvements.
- 13–14 October: Model signals indicated a developing intense low over the Bay of Biscay.
- 15 October afternoon: Official warnings were issued for strong winds across southern England.
- 15 October night–16 October morning: The strongest winds occurred, exceeding forecasts for some inland areas.
- Post-event: Independent inquiry and research led to better understanding of sting jets and forecast guidance.
Direct Impacts: Damage and Disruption
The storm’s most visible impacts were widespread wind damage to structures, trees, and infrastructure. In south-east England, many mature trees were uprooted or snapped, blocking roads and damaging homes, schools, and utilities. Power networks suffered substantial outages, with some areas without electricity for several days. Transport networks were heavily disrupted: rail services were suspended, roads blocked by debris, and ports temporarily closed. Insurance claims surged, and the economic cost was significant, though exact figures vary across reports. No major coastal flooding resulted from the storm, distinguishing it from some later extratropical cyclones, but inland flooding from intense rainfall occurred in a few locations after the winds eased.
Human and Social Impact
Twenty-two people died across the UK, with most fatalities resulting from falling trees or debris. Many more were injured, and hundreds of thousands of households faced disrupted power and communications. The scale of fallen trees—often in suburban areas—created protracted cleanup efforts, while the loss of mature trees had lasting landscape and ecological effects. Communities experienced significant disruption, prompting reviews of emergency preparedness and public communication for future events.
Response, Recovery, and Investigations
In the immediate aftermath, emergency services, local authorities, and utilities coordinated rescue and temporary power restoration. The military and voluntary organizations supported clearing roads and assisting affected communities. Government and industry inquiries examined forecasting, warning effectiveness, and response coordination. Their findings emphasized better integration of research into operations, improved communication of risk, and reinforced infrastructure resilience. These reviews contributed to long-term reforms in the UK’s meteorological and civil contingency arrangements, influencing how subsequent severe wind events were managed.
Long-Term Legacy and Changes
The Great Storm of 1987 reshaped practices in meteorology, forestry, and infrastructure planning. Forecasters improved models to better represent rapid intensification and sting-jet dynamics, enhancing warnings for future extratropical cyclones. Arboreal management practices evolved, with increased attention to tree species selection, pruning, and risk assessment near infrastructure. Insurance products and building standards also adapted in response to wind risk in southern England. The event remains a reference case for studying extratropical cyclones and for communicating low-probability, high-impact weather to the public and decision-makers.
Context and Common Questions
Because the term "UK hurricane" is used in media and conversation, it is useful to distinguish between tropical hurricanes and this extratropical storm. While the Great Storm of 1987 is not classified as a tropical cyclone, it exhibited very strong winds and caused comparable disruption. Understanding its origins, forecast evolution, and impacts provides insight into how the UK weather system has adapted to manage severe wind risk. The storm also underscores the importance of continued research, data collection, and cross-agency coordination for future resilience.
