Severe Thunderstorm Warning Issued for Auvergne-Rhône-Alpes Region
A widespread threat of thunderstorms and heavy showers is forecast to impact the Auvergne-Rhône-Alpes region of France this Wednesday, August 27, prompting authorities to issue orange vigilance alerts for multiple departments. Residents are urged to prepare for potentially hazardous conditions, including strong winds and hail.
Orange Vigilance Declared Across Seven Departments
Several departments are bracing for impact, with orange vigilance – the second-highest alert level – set to take effect this afternoon. According to forecasts, the Cantal, Haute-Loire, Puy-de-Dôme, Loire, Rhône, Saône-et-Loire, and Ain departments will be under heightened alert. The Cantal, Haute-Loire, Puy-de-Dôme, Loire, and Rhône will transition to orange vigilance at 2 p.m. local time, while the Ain will follow at 4 p.m.
Storms Expected Throughout the Day
The approaching weather system is expected to bring storms throughout the entirety of Wednesday, impacting a large portion of the Auvergne-Rhône-Alpes region. “It will rumble in the sky,” one source noted, underscoring the anticipated intensity of the storms. While the Provence-Alpes-Côte d’Azur (PACA) region is expected to be spared from the severe weather, residents in Auvergne-Rhône-Alpes should anticipate sustained periods of rain and thunderstorms.
Hazardous Conditions Anticipated
Beyond the rainfall, the primary concern lies with the potential for strong, damaging winds. Gusts ranging from 60 to 80 km/h are forecast, with localized areas potentially experiencing winds up to 100 km/h. The possibility of hail also presents a significant hazard.
Temperatures will remain relatively mild despite the inclement weather. Forecasts predict highs of 21 degrees Celsius in Clermont-Ferrand, 22 degrees in Millau, 23 degrees in Puy-en-Velay, 24 degrees in Saint-Étienne and Bourg-en-Bresse, 26 degrees in Chambéry, Vienne, and Lyon, and 27 degrees in Bourgoin-Jallieu. Evening temperatures are expected to drop to between 17 and 21 degrees Celsius.
Traffic Disruptions Possible
Travelers should be aware of potential disruptions. The Mont-Blanc tunnel is currently closed for more than three months following initial work conducted last year, adding to potential transportation challenges in the region.
Residents and visitors are advised to stay informed of the latest weather updates and heed any guidance issued by local authorities. The situation remains dynamic, and continued vigilance is crucial as the storm system approaches.
