Isère, Loire and Haute-Loire placed on orange snow and ice alert. Snow could fall above 400 m, enough to impact the Saint-Etienne metropolitan area and Terres Froides.
A disturbance accompanied by significant rain will indeed affect the Rhône-Alpine region this Tuesday at the end of the day. The rain-snow limit will drop to around 600 m overnight, causing 10 cm of snow in Le Puy and 20 cm on the plateaus at 1,000 m altitude.
