Managing Critical Communications Under Extreme Conditions: ACMOSS at the Core of the Storm Goretti Response

How real-time network supervision supported communications continuity during a major weather emergency in northwestern France.

In early January 2026, Storm Goretti swept across northwestern France, bringing violent winds that exceeded 150 km/h in several coastal areas. The storm caused widespread disruption to transport infrastructure and power grids and placed severe strain on local telecommunications networks. In this context, the Agency for Operational Mobile Communications for Security and Emergency Response (ACMOSS) played a central role in supporting crisis management efforts.

A strategic supervisory role during the crisis

Throughout the event, ACMOSS relied on its Operations Supervision Center (Network Operations Center – NOC) to maintain continuous coordination with the priority operators of the Future Radio Network (RRF), Bouygues Telecom and Orange. Acting as a key monitoring and coordination platform, the NOC enabled close operational alignment between stakeholders, providing real-time visibility of network outages and supporting the prioritisation of coverage restoration in the most affected areas.

This capability allowed decision-makers to track the evolution of incidents as they unfolded and to guide interventions with a clear operational overview. ACMOSS’s involvement during Storm Goretti once again demonstrated its strategic role in managing telecommunications-related crises and its capacity to intervene in a focused, operational, and effective manner during large-scale emergencies.

The NOC: ensuring continuity of RRF services

During major weather events, the continuity of communications is a critical requirement for security and emergency response operations. The Operations Supervision Center teams are equipped with advanced tools that allow them to manage alarms and incidents while maintaining a precise, real-time view of 4G and 5G coverage across the national territory.
These capabilities enable ACMOSS to anticipate and analyse potential threats—particularly weather-related or environmental risks—that may affect services, to detect and assess network outages at an early stage, and to provide direct operational support to security and emergency services relying on the RRF for their mission-critical communications.

Rather than relying on a fixed threshold to define critical antenna losses, the priority remains maintaining overall network coverage and preventing service gaps. In this context, the NOC plays a pivotal role through its 24/7 supervision of both radio access networks and core network infrastructures.

The experience of Storm Goretti highlights the importance of robust, continuously supervised communications infrastructures and confirms ACMOSS’s position as a key actor in ensuring service resilience and operational continuity during national-scale crises.
