Severe Weather Alerts Issued as Mediterranean Episode Intensifies
A powerful storm system named Harry is poised to batter Southern France this weekend, bringing catastrophic rainfall, severe flooding risks, and heavy mountain snow. The Spanish Meteorological Agency (AEMET) officially named the storm on Friday, January 16, 2026, warning of its significant impact across Western Europe.
Meteorologist Yann Amice warns of a “high risk of floods and inundations” for southeastern France, including Corsica, beginning Saturday, January 17. The cause is a deep depression stalled between the Balearic Islands and Algeria, funneling a persistent, moisture-laden southeasterly flow directly into the region.
Widespread Weather Warnings Activated
Météo-France has escalated warnings, placing two departments on Orange Alert:
- Hérault for rain-flooding
- Aude for flooding
An additional 23 departments are under Yellow Alert for a combination of threats including rain-flooding, avalanches, thunderstorms, and strong winds. The affected areas span from the Pyrenees to the Alps and across Mediterranean coastal regions.
Extreme Precipitation Forecast
Weather models predict staggering accumulations by Tuesday, January 20:
- Over 300 mm of rain in parts of the south.
- More than 1 meter of snow above 1,400 meters in the Pyrenees.
Key areas of concern include Carcassonne, Narbonne, Perpignan, Béziers, Corsica, and the departments of Gard and Lozère. A full-blown Mediterranean episode is expected, with sustained rain on the Cévennes relief and plains, coupled with coastal wind gusts potentially exceeding 100 km/h.
Persistent System Brings Prolonged Risk
The blocking pattern, with cold air aloft and high pressure to the east, is causing the depression to stall. “This leads to risks of floods and overflows with significant and, above all, long-lasting rains,” emphasizes Amice. Spanish authorities have also issued alerts for potential coastal damage, falling debris, and local flooding.
Northeast Brings a Chill to the North
While the south battles deluges, the storm’s positioning will draw a cooler continental air mass from the northeast over the rest of France. This will bring a return of morning frosts and daytime temperatures struggling to reach 10°C next week, marking a sharp drop from recent mild conditions. This is a return to seasonal norms, not an extreme cold wave.
Broader Climatic Context
The severe weather follows a notably warm year. Météo-France’s climate report, published January 15, confirmed 2025 as the fourth hottest year on record in France since 1900. The data showed temperatures were above seasonal norms one out of every two days, underscoring the rapidly evolving climate backdrop to such extreme weather events.
