NORTHERN SAN JUAN

WEATHER DISCUSSION:
The wind keep blowing persistan on a NW direction on the Front Range. Apparently also all the next week the Northern San Juan is going to be covered by clouds, but there isnt any signal of precipitations. Temperatures are gonna get higher, especially during the weekend.
SNOWPACK DISCUSSION:
On the West side of the zone there should be trigged slides, wich were all soft slabs, and all ran on hard polished bed surfaces abd will probably bring on some repeated offenders when we move back into a storm cycle.
Near Red Mountain pass a fresh hard slam has been reported, it looks like a cornice fall triggered it (50 feet wide, it ran 50 vertical feet). There were a couple more shallow slabs on teh south aspects near the pass (6-8 inches deep). Another larger soft slabran near Ophir on a SOuth-West direction (it ran about 2200 feet).
The winds are coming down, beside they're still strong, but in fact they already created some damages. There's not a whole snow to move off the windward aspects to the northerly winds anymore.
AVALANHCE DANGER:
The avalanche danger for the Northern San Juan zone is moderate near and above treeline all aspects. The danger is low below treeline. Human triggered slides will mostly be shallow and confined to upper snowpack layers, though deep slab instabilities persist.
