Conditions are likely to deteriorate on Monday as a Northerly storm arrives. Rain/snow and gale force winds are forecast.
Expect an increase in avalanche danger over the next 24 hours.
Gale Northerly winds and rain/snow are forecast. Be on the lookout for Wind Slab formation particularly, on slopes facing North East through to South West above about 1700m. Be prepared to alter your plans if conditions appear likely to deteriorate rapidly.
Loose Wet avalanche activity is a possibility if it begins to rain. These failures could occur on any aspect. Head for home if persistent rain looks likely.
No avalanche activity reported recently.
If you see evidence of avalanches in the back country please enter a public observation.
New snow will land on a shallow, weak snow pack. Buried rime crusts have been identified in places. Also, recent cold clear nights have been driving facet development (weak, sugary forms). Crust and facet layers will be tested over the next few days as the load sitting on them increases.
Monday - rain developing late morning with heavy falls possible. Snow down to 1400m. Northerly winds rising to gale/severe gale force. Freezing level - 1300m climbing to 1900m in the afternoon.
Limited sliding danger at present.
