Lo esencial

Wet loose avalanches are most likely when new snow sees warming for the first time.

Triggerable wind slabs may still exist in alpine terrain.

Problemas de aludes

  • Wind Slabs

    • Bajo el límite del bosque
    Probabilidad
    Unlikely - Possible
    Tamaño
    1–2

    Recent storm snow may remain reactive to rider-triggering in wind-loaded areas, particularly where it overlies a slick crust.

    New snow weakens as it sees warm temperatures for the first time. Watch steep, solar slopes and areas around rocks where these small avalanches could be easier to trigger.

Snowpack Summary

Up to 30 cm of recent snowfall overlies a crust.

Snow depths at treeline vary across the region from 230 cm near Mt. Washington to 130 cm near Mt Cain.

Avalanche Summary

No new avalanches have been reported in the past few days, but field observations are limited.

If you are going out in the backcountry, please consider filling out a Mountain Information Network (MIN) report.

Terrain and Travel Advice

  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches.
  • Carefully evaluate steep lines for wind slabs.
