Air quality in the Chamonix Valley over the last few days peaked yesterday with particles of pollutants in the air exceeding the 50 / 80μg / m³ threshold.

Monitoring air quality levels will continue as if the current situation worsens, there could be an ban on heavy vehicles throughout the Arve Valley and restrictions put into place for inhabitants of the region, as we saw back in July. Hopefully today’s weather conditions, with mid and high level clouds passing through, will mean that air quality improves at least in the short term.
