Jasper National Park Avalanche Forecast
May 4th, 2019 4:00PM
Good skiing can still be found in sheltered areas in the alpine.
Sunday broken skies and no new snow, Freezing levels to rise to 2300M
Monday broken skies with no new snow, Freezing levels to 2500M
Tuesday mix of sun and cloud with no new snow, Freezing levels 2600M
10cm-20cm recent snow (elevation dependant) covers widespread wind effect from previous N winds, overlying crusts and facets in upper snowpack. The crusts are bridging on solar aspects. Occasional whumpfing at upper TL and in the ALP. Snowpack structure is generally faceted on polar aspects and weak in shallow areas.
No new observations from field teams today.
Weak mid-pack facets found in sheltered upper treeline and alpine features, loaded by recent new snow and moderate SW winds may overload this interface. Not likely to trigger naturally but sensitive to human triggering.
- Good group management is essential to manage current conditions safely.
- Watch for signs of instability such as recent avalanche activity, and whumpfing/cracking underfoot.
Expected Size1 - 2.5
- Use caution in lee areas. Recent wind loading has created wind slabs.
- Keep an eye out for reverse loading created by an upslope storm.
Aspects:North, North East, East, South East, South.
LikelihoodPossible - Unlikely
Expected Size1 - 2
