Meteorological services forecast an intensification of stormy showers from late Friday night through Saturday morning. Rainfall intensity could reach 30 to 40 mm per hour. Following a brief lull expected around midday, heavy showers are set to resume in the afternoon.
Total rainfall is estimated between 70 and 100 mm in the Hauts Cantons and plains, with local peaks reaching 150 mm. On the coast, forecasts expect 60 to 90 mm, with localized peaks between 100 and 130 mm. The risk of whirlwind phenomena is also highlighted for coastal areas.
The Frontignan Town Hall notes that the ground, already saturated from the previous Wednesday's rainfall, remains highly sensitive to runoff. A return to calmer conditions is expected by the evening and the following night as the rain tapers off.
Extreme caution is advised during any travel. Special attention should be paid to ford crossings, which are discouraged due to the risks associated with rising water levels.
