Natural avalanches are unlikely, human-triggered avalanches are possible. Small avalanches in specific areas, or large avalanches in isolated areas.
Hot and sunny weather is settling in for a couple of days what might bring an end to the current deep persistent weak layer problem (yet this is still a subject for further investigation) but at the same time make a wet loose and glide slab avalanches more likely. Such conditions make it preferable to limit all the backcountry activities to the morning hours and early afternoon.

Crusts with weak, sugary snow above and below them have been seen in the upper and mid snowpack (below the 22.03-25.03 new snow layers). These layers have caused recent large avalanches. A large slab avalanche could be started by a smaller surface avalanche, a heavy load, or by a rider hitting the 'sweet spot' (often an area where the overlying slab is thinner). These problems remain in the high alpine and on shaded slopes in the alpine and in areas where the snowpack is shallower. Warm temperatures will eventually stabilise these layers but they might become more active for a while first - treat steep slopes with caution!

Such avalanches are now present even as high as 2900 m. and are becoming more and more widespread, These are unlikely to be triggered by a rider and often happen naturally so should be taken into consideration while traversing areas below the spots where such avalanches might occur - steeper slopes with grassy or smooth rock underlying surface and slopes where the glide cracks are visible.

Trend | Deteriorating |
Confidence | Moderate |
A combination of a high freezing level, sun and still possible areas of cloud creating a greenhouse effect will make loose snow avalanches likely in steep areas. These slides may also be the trigger for a larger slab avalanche on slopes below. Stay away from steep areas if you see evidence of snow movement, and when the snow is unsupportive, wet and sticky.

Recent avalanche activity:
31 March - glide slab avalanches on E slopes in Kobi valley at around 2900
28 March - two size 1.5-2 slab avalanches on Bidara E face at 2900 m. (at least one possibly triggered from a distance of 50-100 m. by a snowmobile)
27 March - multiple size 2 windslabs seen on Lomisa - Miketi ridge E and NE, 2000 - 2900 m, some involved deeper layers.
26 March - multiple large slabs on Sadzele W and NW aspects 2900 - 3200 m, triggered by expolsives - including three size 3 slides.
25 March - Multiple size 3 slabs, N aspect along the ridge E of Arakhveti on or near Mujukhi.
Glide slabs are active on multiple aspects (more commonly E, S and W), some up to size 3. These are more likely in warm weather but can release at any time - if you see cracks in the snow, do not stop under these areas!
Snowpack:
Around 80 cm of new snow fell between early Friday 22nd and Monday 25th. Subsequent warmer period with daily melt-freeze cycles possibly contributed to stabilisation of the existing weak layers (still to be confirmed) and formed widespread crusts on top of the snowpack. Ongoing heat, however, contributed to widespread wet avalanches. Snowpack might be becoming isothermal on lower elevations,
Clear, no precipitation or significant winds are forecasted. Air temperature will gradually rise up through 1st and 2nd of April reaching as high as 8C at 2000 (and 1.5C at 3000) on 3rd of April. At the same time freezing level rises up to 3000 m. mid-day.
