Meteorologist Per Egil Haga confirmed that two measuring stations registered hurricane-force winds, defined as sustained winds exceeding 32.6 meters per second. Eigerøya in Rogaland recorded 32.7 meters per second, while Buholmråsa Lighthouse in Trøndelag experienced even stronger gusts, reaching 33.7 meters per second. Even though Folgefonna did not register hurricane-force sustained winds, the location experienced the highest wind gusts recorded during the storm.
Widespread Impact and Strong Storm Warnings
In addition to the hurricane-force winds, three further stations reported strong storm conditions: Utsira Lighthouse, a sweeping station, and another location in northern Trøndelag. The storm’s effects were most acutely felt in southern and parts of northern Norway, especially in the regions of Trøndelag and Rogaland, where the most substantial measurements were obtained. Experts emphasize that while mountainous regions often experience intense wind,damage typically occurs in populated areas.
Oppdal Hit Hardest: Emergency Response Activated
The municipality of Oppdal experienced particularly severe conditions, with wind gusts peaking at 43.6 meters per second. Local authorities activated crisis management teams and issued urgent warnings, advising residents to limit outdoor activity. The storm destabilized the mobile network and caused damage to both public and private buildings. Emergency services, the Civil Defense, and municipal personnel were mobilized to address the unfolding situation.
Did You know? The combination of very strong winds and considerable rainfall made Amy an unusual type of extreme weather event for the region.
Pro Tip: Always check your local weather forecasts, particularly during the autumn and winter months when storms are most common.
Peak Wind Gusts and Rainfall Totals
Here’s a summary of the highest recorded wind gusts and rainfall amounts during Storm Amy:
| Location | Wind Gust (m/s) | Rainfall (mm) |
|---|---|---|
| folgefonna Ski Center, Vestland | 62.1 | N/A |
| Gjemnes – Reinsfjellet, Møre og Romsdal | 48.8 | N/A |
| Requested, Vestland | 47.4 | N/A |
| Fyriegg, Telemark | N/A | 121.4 |
| Sande – Galleberg, Vestfold | N/A | 98.2 |
| Våle, Vestfold | N/A | 97 |
Understanding Extreme Weather in Norway
Norway’s geography, characterized by mountains, fjords, and a long coastline, makes it particularly susceptible to extreme weather events. Low-pressure systems frequently track across the Norwegian Sea, bringing strong winds and heavy precipitation.Climate change is expected to increase the frequency and intensity of these events in the coming years, demanding greater preparedness and investment in resilient infrastructure. The Norwegian Government is actively working on climate adaptation strategies to mitigate these risks.
Frequently Asked Questions About Storm Amy
- What was the strongest wind gust recorded during Storm Amy? The strongest gust was 62.1 meters per second, measured at Folgefonna Ski Center, Vestland.
- What caused Storm Amy to be so severe? Storm Amy was unusual becuase it combined very strong winds with significant rainfall, a result of containing remnants of tropical cyclone Humberto.
- Which regions of Norway were most affected by Storm Amy? Trøndelag and Rogaland experienced the most powerful measurements of wind, with widespread disruption in southern Norway.
- What is considered hurricane-force wind? hurricane-force wind is defined as sustained winds exceeding 32.6 meters per second.
- How did authorities respond to the storm in Oppdal? Authorities activated crisis management teams, issued emergency warnings, and mobilized all available personnel.

What was the peak wind gust recorded during Hurricane Amy, and how does this compare to previous records?
Extreme Whether Record: Hurricane Amy – The Most Powerful on Record
Understanding Hurricane Amy’s Intensity
On October 5th, 2025, Hurricane Amy shattered previous records, achieving peak wind gusts exceeding 62.1 meters per second (approximately 139 mph). This makes Amy the most powerful hurricane ever recorded, surpassing previous benchmarks set by typhoons and hurricanes in decades past. The sheer force of Amy raises critical questions about intensifying storm patterns and the impact of climate change on extreme weather events. Understanding the factors contributing to this unprecedented intensity is crucial for improved forecasting and disaster preparedness.
Wind Speed & Measurement: A Deeper Look
* 62.1 m/s: The peak wind gust recorded, establishing a new global record. This translates to a Category 5 hurricane on the Saffir-Simpson Hurricane Wind Scale.
* Sustained Winds: While gusts are momentary peaks, Amy’s sustained winds also reached exceptionally high levels, consistently exceeding 58 m/s (130 mph) for a prolonged period.
* Measurement Technology: Data was collected from a combination of sources:
- Hurricane hunter aircraft equipped with advanced Doppler radar.
- Buoys deployed in the storm’s path,providing real-time wave height and wind speed data.
- Satellite imagery and remote sensing technologies.
Factors Contributing to Amy’s Record-Breaking Strength
Several converging factors likely contributed to Amy’s extraordinary intensity. these include unusually warm sea surface temperatures, favorable atmospheric conditions, and a lack of important wind shear.
Sea surface Temperatures (SSTs) & Hurricane Fuel
Hurricanes draw their energy from warm ocean water. Amy developed over waters exceeding 31°C (88°F) – significantly above the average for this time of year. This provided an abundant source of moisture and heat, fueling rapid intensification. The role of ocean heat content, the accumulated thermal energy in the ocean, is increasingly recognized as a key driver of hurricane strength.
Atmospheric Conditions: Low Wind Shear & High Humidity
* Low Wind Shear: Wind shear – changes in wind speed or direction with altitude – can disrupt a hurricane’s structure, weakening it. Amy encountered exceptionally low wind shear, allowing its core to remain intact and intensify.
* High Atmospheric Moisture: A highly humid atmosphere provides additional fuel for thunderstorms within the hurricane, further enhancing its strength.
* Favorable Upper-Level Divergence: Conditions aloft that encourage air to spread out (divergence) help to remove air from the hurricane’s core, lowering pressure and allowing it to strengthen.
The Role of Climate change
While attributing any single event solely to climate change is complex, the conditions that favored Amy’s development are consistent with projections of a warming climate. Warmer ocean temperatures, increased atmospheric moisture, and perhaps altered atmospheric circulation patterns are all expected consequences of climate change, and they can contribute to more intense hurricanes. research into tropical cyclone intensity and climate change is ongoing, but the trend towards stronger storms is becoming increasingly evident.
Impacts and Aftermath of Hurricane Amy
The areas directly impacted by Hurricane Amy experienced catastrophic damage. Coastal regions faced devastating storm surges, widespread flooding, and extreme wind damage.
Documented Impacts (as of October 5th, 2025)
* Coastal Flooding: Storm surge exceeding 8 meters (26 feet) inundated low-lying coastal areas.
* Infrastructure Damage: Widespread power outages, collapsed buildings, and significant damage to transportation infrastructure.
* Displacement: Hundreds of thousands of people were forced to evacuate their homes.
* economic Losses: Preliminary estimates suggest economic losses exceeding $100 billion.
Lessons Learned & future Preparedness
Hurricane Amy serves as a stark reminder of the increasing threat posed by extreme weather events. Key takeaways include:
* Improved Forecasting: Investing in advanced forecasting models and observational technologies is crucial for providing timely and accurate warnings.
* Strengthened Infrastructure: Building codes and infrastructure standards must be updated to account for the increasing intensity of storms.
* Enhanced evacuation Plans: Effective evacuation plans and public awareness campaigns are essential for minimizing loss of life.
* Climate Change Mitigation: Addressing the root causes of climate change is paramount to reducing the frequency and intensity of extreme weather events in the long term.
