Storm Regina: Saharan Dust and Heavy Rainfall Alert for Southern France
PARIS, 04 March 2026 – A powerful low-pressure system named Storm Regina is currently sweeping across South-Western Europe, bringing a rare combination of “blood rain,” intense Saharan dust plumes, and gale-force winds to the Mediterranean coast and the Pyrenees.
Atmospheric “Blood Rain” and Dust Plumes
Named by the Portuguese Meteorological Institute (IPMA), Storm Regina originated over North Africa before moving northwards through the Gulf of Cadiz. The system is transporting a massive concentration of Saharan mineral particles across the Iberian Peninsula and into Southern France. This phenomenon, often referred to as “blood rain,” occurs when precipitation washes suspended dust out of the atmosphere, leaving a reddish film on vehicles and buildings.
Air quality warnings have been issued for the Occitanie and Provence-Alpes-Côte d’Azur regions. Health officials advise vulnerable individuals to limit outdoor physical activity as the dust plume reaches peak density between Wednesday and Friday.
Impact on Southern France
While Spain and Portugal have already faced winds exceeding 70 km/h, the storm is expected to intensify as it interacts with the Mediterranean climate. Forecasters predict that the Aude and Pyrénées-Orientales departments will bear the brunt of the instability. Meteorological models indicate a “Mediterranean episode” characterized by stationary heavy rainfall, with some areas expecting up to 20 litres of water per square metre in a single hour.
In the higher altitudes of the Pyrenees, the storm is expected to deliver significant snowfall, though the “yellow” dust may discolour the snowpack, potentially accelerating melt rates due to increased solar absorption.

Travel and Safety Advice
The Foreign Office has updated travel advisories for British nationals in Spain and Southern France, citing potential visibility issues on motorways due to the dust haze.

Residents are urged to secure outdoor furniture and monitor local Météo-France bulletins as the 17th named storm of the season progresses.
Frequently Asked Questions
What is “blood rain”?
“Blood rain” is a non-scientific term used when rain carries high concentrations of red-coloured dust or sand from deserts, such as the Sahara. When the water evaporates, it leaves a visible layer of dust on surfaces.
Is Storm Regina related to the 1912 Regina Cyclone?
No. The 1912 Regina Cyclone was a devastating F4-scale tornado that struck Regina, Saskatchewan, in Canada. The current Storm Regina is a European low-pressure system named according to the 2025-2026 international storm-naming list.
How long will the Saharan dust last in France?
The plume is expected to remain concentrated over Southern France until late Friday, 06 March 2026, before shifting eastwards towards Italy and the Northern Balkans as the pressure system dissipates.
