Storm Amy Hits Northern France with Heavy Winds and Rain on October 4, 2025

Storm Amy, described as a "meteorological bomb" by the UK Met Office, is set to impact northern France on Saturday, October 4, 2025, bringing strong winds and heavy rainfall across multiple regions. Originating after cyclone Humberto, Amy is sweeping from the west to the east of the country, affecting 55 departments under yellow weather alerts, including Ain, Aisne, Calvados, and Paris.

Meteorological forecasts warn of wind gusts reaching up to 110 km/h along the coastline, with some areas along the Manche, particularly from Seine-Maritime to Pas-de-Calais, expecting gusts as high as 120 km/h. The northern and northwestern parts of France will experience sustained rainfall from the Loire region to the Belgian border, with possible hail showers and thunderstorms near the Manche and north of the Seine.

Temperatures in the northern half of France will remain cool, not exceeding 20 °C, with specific readings such as 14 °C in Lille and Rouen and 15 °C in Paris. In contrast, Mediterranean areas will enjoy warmer weather, with temperatures ranging from 25 to 29 °C.

The morning will witness brief but intense rain extending further south by midday. Inland wind speeds could reach 100 km/h, with the Vosges ridges experiencing gusts over 100 km/h. By evening, the storm and associated cold front are anticipated to move towards Belgium and Germany, leading to clearer skies in the affected French regions.

Following the storm's passage, calmer weather is expected on Sunday, although strong winds may persist around the Mediterranean, especially in Provence.

This storm marks a significant weather event for France, requiring vigilance and preparedness across the impacted departments as the nation braces for potentially disruptive wind and rain conditions.
