Storm Nils Leaves At Least Two Dead, Triggers Rare Red Avalanche Alert and Widespread Power Outages in France

Storm Nils has left a trail of destruction across southern and central France, claiming multiple lives, prompting rare avalanche warnings in the Alps and causing widespread power outages affecting roughly 850,000 customers. The powerful system also disrupted travel across parts of Spain and Portugal as emergency services worked to cope with the aftermath of severe weather.

Fatalities reported as Nils batters France

French authorities confirmed that at least two people died due to Storm Nils. One victim was a truck driver killed when a tree smashed through his windscreen during high winds, and another person died in the Tarn-et-Garonne region after falling from a ladder in their garden.

The storm’s severe conditions also contributed to a spate of weather-related incident reports across the region, with authorities warning that the count of casualties could rise as crews reach isolated areas still cut off by wind-blown debris and flooding.

Avalanche danger escalates to rare red alert

In the French Alps, the heavy snowfall and high winds triggered a **rare red avalanche warning** in the Savoie region, according to meteorological reports. Such alerts are only issued when multiple avalanche paths become highly unstable and the risk of large, spontaneous slides is critically elevated.

Local officials urged residents and visitors to avoid steep mountain slopes and to heed all safety advisories, as red warnings indicate a level of danger where even cautious backcountry travel can be life-threatening.

Hundreds of thousands without power as storm rips through grids

Electric utility operator Enedis reported that roughly **850,000 customers** were left without electricity after the storm’s winds and flooding damaged infrastructure across southern France. As of early Friday, around half of affected users had been reconnected, but crews faced delays due to flooded roads and waterlogged fields.

Enedis mobilized thousands of technicians to address downed lines, fallen poles and damaged substations, but repair work was hindered by ongoing severe weather conditions and inaccessible stretches of countryside.

Transport disruption in France, Spain and Portugal

Storm Nils brought widespread travel chaos: flights, trains and ferry services were cancelled or delayed as high winds and flooding made travel unsafe. Roads across southern France were blocked by fallen trees and floodwater, while emergency services dealt with multiple reports of vehicles stranded on hazardous stretches.

Across the border in Spain, dozens of weather-related injuries were reported and one woman died after the roof of an industrial warehouse collapsed under the force of gale-force winds. In Portugal, heavy rains and flooding caused part of a viaduct to collapse, cutting a key transport link and heightening concerns about infrastructure resilience in the face of extreme weather.

Why Nils was unusually strong

Meteorologists described Storm Nils as “unusually strong” for mid-February, with deep low-pressure dynamics over the Bay of Biscay enhancing wind speeds and producing bands of intense precipitation as the storm moved eastward. The system followed several other extreme weather events in southwestern Europe, including severe floods in Spain and Portugal that forced evacuations and claimed lives.

Climate scientists note that rising greenhouse gas concentrations are linked to greater atmospheric instability and stronger storm systems, a factor that may be enhancing both the frequency and intensity of extreme weather in Western Europe.

Ongoing impacts and what to expect

Emergency and utility crews continue to address the most pressing impacts of the storm. Power restoration efforts are ongoing, with authorities urging residents in affected areas to stay updated on local warnings and avoid flood-prone zones, especially where water remains over road surfaces.

Further rain and melting snow in higher elevations could complicate recovery efforts, maintaining a risk of localized flooding. Avalanche risk in mountainous regions remains elevated due to deep snowpacks and recent wind loading.

With the worst of Storm Nils now eastward, local forecasters caution that its effects will be felt for days as communities recover and repair critical infrastructure.
