FORECAST:
Upper level ridge will bring sunny skies to the area today in a warm Southerly flow aloft. A weak front moves down the coast but should only bring some cloud to the area on Thursday. Unlikely but possible to see a snow flurry in the alpine. Ridge deflects the low to the North bringing a mix of sun and cloud for Friday. We may see some precipitation on Sunday according to the European Model. NAM & GFS are calling for precip by Monday. Guesstimates: 0-trace by Thursday night.
AVALANCHE ACTIVITY:


On Tuesday afternoon numerous size 1-1.5 wet loose avalanches from steep south aspects were reported. A large natural avalanche size 2-2.5 from a north-facing alpine slope was also reported and likely occurred Monday night.
On Monday explosive triggered storm and wind slab avalanches were reported up to size 2.5. Crown depths generally ranged 20-50 cm, with a 120 cm deep crown observed in a heavily wind loaded feature.
Our eyes and ears in the mountains are limited at this time of year and may continue this winter due to fewer professional observations. If you see anything (or don't) while out in the field, please consider sharing via the Mountain Information Network (MIN).

The Evo 5 capitalizes on Arva’s 35 year expertise to fit in the palm of your hand. With a 50 M search strip width, group check, marking function, auto revert to transmit mode, the Evo 5 is jam packed with all of the essential functions needed to rescue an avalanche victim.
How does it keep you safe? When you turn the Evo 5 on, it stays on. The shut off involves pushing a button in and then sliding the arm into the off position. Then it requires you to push the flag marker to confirm this in the next 5 seconds or the transceiver will remain in send mode.
