Storm Olivier: France Braces for Dramatic Weather Shift
France is preparing for a dramatic shift in weather as Storm Olivier approaches, bringing with it significant rainfall and thunderstorms starting this weekend. Following an unusually warm and sunny week, the storm will mark a stark contrast, impacting much of the nation.
A Calm Before the Storm
On Thursday, April 10, 2025, pleasant conditions prevailed across France with temperatures ranging from 18 to 22°C, reaching up to 26°C in southern regions. Météo France reported mostly clear skies. However, this idyllic weather is short-lived.
Storm Olivier's Arrival
By Friday, April 11, 2025, a disturbance will begin affecting southwestern France, signaling the arrival of Storm Olivier. Originating near the Canary Islands, the storm has already caused heavy rainfall there and is projected to move through southern Portugal before reaching France. Meteorologists warn of intensifying conditions starting Saturday.
Weekend Weather Warnings
Saturday, April 12, 2025, will see increasing cloud cover and unstable weather along the Atlantic coast, with afternoon rain and scattered thunderstorms developing from Bordeaux to Orléans, potentially reaching Paris by evening. Sunday, April 13, 2025, will see the unstable weather shift eastward, affecting the Massif Central, Occitanie, Auvergne-Rhône-Alpes, and the Alpes-Maritimes. Heavy rainfall is expected, especially in mountainous regions, with potential accumulations reaching 100 to 150 mm over two days. Meteorologists, like Paul Marquis, warn of the risk of landslides and flooding due to snowmelt and significant rainfall at all altitudes.
Strong Winds and Continued Instability
Storm Olivier will create a low-pressure corridor across France, resulting in showers, thunderstorms, and strong winds. The Autan wind will return, with gusts potentially reaching 90 km/h in the southwest. The storm's effects are expected to continue into Monday, April 14, 2025, particularly in the Mediterranean region.
Preparing for the Storm
Residents, especially in southeastern France, are urged to prepare for the significant rainfall and potential consequences of Storm Olivier. The rapid change in weather conditions necessitates preparedness for flooding, strong winds, and disruption to daily life.
