The Cupid of Romance is deep in summer mode. Expect green ski runs, sightseeing lifts, hiking trails and zero ski operations. The snow forecast is less a forecast and more a firm no. Put ski wax on the shopping list and keep the snow alerts quiet for now.
Start with overnight snowfall and wind direction. The headline number only helps once you know whether a cold inland trough is the pattern to watch. With a 475 to 1271 metre elevation band and 796 metres of vertical, the trees and upper storm laps hold soft snow well after the open faces are worked. A seasonal baseline around 10 metres means moderate-looking totals can still refresh the main lines quickly. The swing variable is wind: light flow lets the trees refill, while a hard blast strips the exposed entrances. If you are looking beyond the ropes, only chase that angle when the forecast also shows settled wind and stable visibility. Chase it when 10 to 20 cm lands overnight with light to moderate wind; if gusts climb, make it a sheltered-tree day.
