The winds of the Sahara are flying over the department, but the phenomenon is less important than at the beginning of the month. However, the concentration of sand in these hot air currents is expected to peak during the night of Tuesday 21 to Wednesday 22 February.
Good news: air quality is saved more than in the first episode. Sand is a fine, naturally-occurring PM 10 particle that can cause irritation to the most sensitive people.
Limit vigorous physical activity
Until the end of this meteorological episode in Ain, scheduled for Wednesday February 22, the prefecture has thus transmitted some recommendations. In particular, it is advisable to limit strenuous physical activities and keep children away from car pollution.
