There is a MODERATE danger from wind slab avalanches at upper and middle elevations. Strong to gale force winds from the W and NW will continue to lift and transport snow onto leeward slopes. Watch steep terrain below ridges and below cornices. Avoid the edges of cornices in your travels.

Recent Avalanche Activity

Recent Avalanche Activity
No new avalanches have been observed recently.

Current Snowpack Conditions

Current Snowpack Conditions
Conditions remain mostly unchanged from previous reports. Around 10-15cm of heavy, wet new snow fell on Friday. This new snow was capped by a thin rime crust and has had a couple of days to cool down and dry out. The latest new snow has also felt the full effects of strong W and NW winds in some areas. Intense snow transport was observed in the S end of the Craigieburn Range on Sunday afternoon. Some new wind slabs may have developed where snow was deposited on Sunday. Snow transport may continue during the day Monday. Our older/deeper snowpack remains generally stable at this time.

Mountain Weather

Mountain Weather
Continued NW winds for Monday. This will mean moderate to intense snow transport will be possible for most of the day. The wind should ease by evening time. There is a possibility of light precipitation closer to the divide. The freezing level is likely to drop to around 1400m.
