Lo esencial
Recent warm days and cool nights have strengthened the mid and upper snowpack, but changes to the deep persistent weakness will be much slower. A conservative approach is still warranted.

Use caution in shallow snowpack areas where deep weakness might be more reactive to a human load. Build trust slowly in the snowpack before committing to any large rideable slope.

Weather Forecast
An arctic front approaching from the NE brings the potential for upslope flurries Thursday. Followed by bands of precip embedded in a low this weekend, giving strong winds and rising temps.Thurs: Sun and cloud mix, light flurries. Alpine Low -15 C, High -8 C, light ridge wind.A detailed mountain weather forecast is available from Avalanche Canada.
Snowpack Summary
Surface conditions vary thanks to the past weeks drought - a thin crust on steep solar aspects, 5-10mm surface hoar in sheltered areas, and wind effect in exposed areas from moderate-strong SW winds. A generally strong mid snowpack overlies deep persistent weaknesses. Use caution in shallow areas where these deep weakness might be more reactive.
