Forecast tips for Mt. T
Start with overnight snowfall and wind direction. The headline number only helps once you know whether a cold front pushing across the divide is the pattern to watch. With a 750 to 1500 metre elevation band and 750 metres of vertical, the trees and upper storm laps hold soft snow well after the open faces are worked. A seasonal baseline around 15 metres means the headline numbers can be real storm signals rather than background noise. The swing variable is wind: light flow lets the trees refill, while a hard blast strips the exposed entrances. With patrol boundaries in play, focus on how the inbounds snow will hold through the first half of the day. Chase it when 15 to 25 cm lands overnight with light to moderate wind; if gusts climb, make it a sheltered-tree day.
