Overview
- Météo‑France issued the orange-level rain‑and‑flood warning for Pas‑de‑Calais on Saturday for the night window, with the alert running roughly from 20:00–21:00 until about 04:00 the following morning.
- Forecasters expect generally 30–50 mm of additional rain from perturbation Boelo, with showers beginning midday in the northwestern quarter and a peak in intensity in the middle of the night.
- Boelo follows storm Austen within 48 hours, and the new rainfall will add to totals from Austen in saturated catchments and low-lying areas.
- More than 240,000 households lost power after Austen in western and northern France, increasing the risk that floods and ongoing outages could disrupt emergency services and recovery efforts.
- Orange vigilance signals a significant risk that requires local preparedness and monitoring of Météo‑France bulletins because consecutive rain episodes can quickly overwhelm drains, roads and local infrastructure.
