*Strong* (warm) winds coming from the west, changed to coming from the east throughout the morning. Overnight snowfall 2-5cm being transported by strong winds on approach. We were checking out the south face of the Two Sisters and decided nah, not with the wind. Stopped to layer up when we noticed a small slide coming off some exposed rocks on lookers left. And then it just kept going from lookers left to lookers right. Approx 150+ m crown across, likely 10+ cm crown depth, and ran 250+m to the 'valley'. Size 1.5 (or, you tell me). We suspect it was not remote triggered, and more due to a combination of the insane wind and wind loading, and began at those (warming?) rocks. The direct sun had just come out. The run funnelled through where we were about to travel <50m away, so this was a great heads-up moment to route find even more conservatively. I've skied this face many times this time of year and have never seen any evidence of sliding, so it was interesting to see it slide, and to be so close. Variable wind in different locations throughout Nadahini. Stuck to the mellow stuff, great day, found some nice snow.
