Rain and snow showers persisted through the morning, with the rain-snow limit expected to fall further to 7,500 feet (2,300 meters) on Tuesday before showers taper off by evening.While the sight of summer snow may startle some, meteorologists and local tourism officials were quick to note its regularity at altitude. "This is, of course, not unusual... it can snow every month of the year above 1,800 to 2,000 meters," Meteo-Alpes stated in a recent post. Regional sources echoed this, recalling a July 14 slalom event held in fresh snow at La Clusaz last summer.However, forecasters predict the chill will be short-lived. Temperatures are expected to rebound from July 9, setting the stage for a potential third heatwave of the summer.
