Forecast Addendum 2//2023 - 07:00am

Submitted by efalconer on Tue, 02/07/2023 - 5:43am
Recent Observations: 

New snow has significantly improved coverage near and below treeline. Observations gathered from Castle Lake yesterday revealed signs of several old natural wind slabs that broke during the storm on northerly aspects. Surface conditions, most of which have experienced some wind effect, were easy to initiate cracking and blocking within. High northerly winds transported snow over peaks and ridge tops onto southerly aspects. Yesterday, a group in the Eddies reported small touchy pockets of wind slab in steep terrain that could knock someone off their feet. Warming occurred yesterday afternoon, causing roller balls, dripping trees and moistened surfaces.

Mountain Weather: 

The region will receive a glancing blow from a weather system to the north as it progresses inland. Little to no precipitation is expected above 5,000 feet, with light to moderate west and northwest winds. Temperatures will rise into the low 40s with clearing skies and a freezing level of 8,300 feet.  A period of high pressure will begin this evening and persist through Thursday morning.
