Atlantic Low Bruna Drives Rapid Warming Across France

Overview

• The warming began this weekend as south‑westerly flow associated with the Atlantic low named Bruna started to push milder maritime air into France.
• Forecasters expect the warm spell to strengthen into next week with daytime highs hitting about 22–25°C in the South‑West and widespread temperatures above seasonal norms.
• Morning frosts should largely disappear for most regions with overnight lows rising to roughly 10–15°C in many areas and up to about 17°C on the Aquitaine coast.
• The advection of warm air will be accompanied by a return of rain and unsettled weather that will arrive first in the south and spread eastward, raising the risk of heavier precipitation in places.
• Models show the warmth persisting through the next ten days, a pattern driven by Atlantic depressions that bring maritime air and wetter conditions and that will affect soil moisture, transport and local flood risk in exposed areas.
