In sintesi

New snow and wind forecasted overnight so we expect to see avalanche danger begin to increase.  Good travel in the Highwood area but still pretty rugged along the Spray.  LOTS of early season hazards are still out there waiting to ruin your season...

Problemi valanghivi

  • Loose Dry

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Likely
    Dimensione

    Watch for loose dry sluffing out of steeper terrain.  This will be important for Ice climbers to note as they are often in the pinch point of the hourglass where smaller sluffs can have big consequences.

  • Storm Slabs

    • Alta quota
    • Limite del bosco

    Storm slabs will continue to develop in Alpine terrain with recent snow and winds. Winds are forecasted to reach into the strong range overnight.

Confidence

Good - Track of incoming weather is uncertain on Monday

Weather Forecast

Winds are expected to increase as temperatures slowly rise.  We may see 10-15cm of new snow above 2200m over the next 24hrs and a second pulse of more snow on Monday night. 

Avalanche Summary

Only a few small loose dry avalanches were observed.  Forecasters also did see a sz two cornice collapse on Mt Tyrwitt around 12:00.

Snowpack Summary

Up to 15cm recent HST at 2300m (Highwood pass).  HS was on average 50-70cm.  Very little wind affect.  No sheers were noted and the 1027 Melt freeze crust was found 20cm off the ground.  Coverage was very variable and numerous rocks and hazards are still evident.
