New strong gale with low-pressure system Fien

Table of Contents

After the passage of storm Gerard in northern France, a new gale in connection with the Fien depression is expected tomorrow Tuesday in the southwest.

Two weather maps side-by-side displaying the probability of wind gusts exceeding 80km/h versus 100km/h in Southwest France during Storm Fien (Jan 2023).
Granular risk assessment. By comparing probability fields for different thresholds (80km/h vs 100km/h), operators can identify the most critical danger zones and scale their response accordingly.

FROGCAST allows us to quantify the risk of occurrence of strong gusts. In the latest forecast, we can see that strong winds from the Atlantic (>80 km/h) will sweep the whole Pyrenean foothills.

However, the probability of exceeding the storm threshold (100km/h) remains moderate inland. These very strong gusts should remain quite localized, except near the Atlantic and Mediterranean coasts.
