Fair - Timing, track, or intensity of incoming weather is uncertain on Thursday

Overnight and Wednesday: A weak ridge of High pressure will continue to cause cold and dry conditions during the day. The next Pacific frontal system is expected to move into the region by Wednesday evening. Light Westerly winds will become moderate Southwesterly as the storm moves in and brings 10-15 mm of precipitation, that should be snow (15-20 cms) at all elevations.Thursday: Strong Southwest winds and another 10-15 mm of precipitation for southern areas of the region. Freezing level should remain at valley bottoms.Friday: Flurries and gusty Northwest winds as a cold arctic airmass moves in from the Yukon.

No observations were made due to poor visibility. One loud avalanche was heard running in the alpine during the afternoon.

During the storm on Monday the height of the snowpack in Harvey Pass was 225 cms at 2000 metres. There was 20 cms of new snow and the storm slab was 45 cms thick. Moderate to strong Southwest winds were moving snow at treeline all afternoon. There was about another 15 -20 cms of snow after these observations. There was cracking in the soft slab ahead of skis when travelling. We suspect that stiffer wind slab was forming at higher elevations.
