Avalanche: Portage / Placer
Location: Portage to Whittier area
We drove through Portage and into Whittier yesterday and saw many naturally occurring wet loose avalanches. Some of these ran quite far. Also, we had a few photos passed to us by former forecaster Graham Predeger who happened to be on the water in Shotgun Cove. A few larger slabs were triggered by wet loose sluffs and one looks to have been triggered by a snowmachiner. These occurred today, Saturday, April 15, 2023.
These areas saw 1-2′ of new snow on Friday (4.14). The sunshine today warmed the new snow to the point it just started sluffing off the mountainsides around noon to 5pm, and even later.

Example of the higher elevations where the sluffs and slabs were not as big, this is around 2,000-2,500'.
