Beautiful bluebird sky day out there. All resorts ARE open today with most lifts running. Most of the powder has been well tracked and the best bet would've been first down the fresh groomers this morning. Due to warming temperatures, expected to be 10+deg.C , the snow will be softening up as the day progresses and all south aspects will be sun baked and heavy snow. Look for the shaded areas for the better snow today. Grab your sunglasses and sunscreen, get out there and enjoy the uncrowded slopes before the big three day weekend!


The Hira Kawa Snow Study Plot (830m a.s.l.) 0700 hr. reading is:

Sky: Scattered clouds
Temperature: Present: -4.0 C
Maximum: 10.0 C
Minimum: -9.5 C
Wind: Light from the west
Winds aloft: snow plumes from ridge crests with the occasional whisps on lower ridge crests: moderate from northerly vector.
Precipitation: Nil
Barometer and trend: 920 hPa and rising
Height of new snow in 24 hours (HN24): 0 cm
Total depth of snowpack (HS): 88 cm
Foot penetration: 33 cm
Surface: melt/freeze
Density of surface snow: not measure
Crust: 3 cm
Above tree line: Moderate

Tree line: Moderate

Below tree line: Low

N.B. hazard will increase with day time warming. The forecast high in the valley is 9 C.

Avalanche observations:

--Yesterday we observed a 'probable Size 3' {could bury and destroy a car, damage a truck, destroy a frame house, or break a few trees} on the south aspect of Norikura Dake. The fracture line is at about 2,250 m a.s.l. and spans most of the slope. Suspected trigger is wind loading.

On shaded aspects the new storm snow is overlaying the preserved low density crystals of last week's storm.

On southern aspects there are multiple melt/freeze crusts with faceting grains 2 to 3 mm.

Be aware when new snow buries these melt/freeze crusts of February 3rd. Wind transported snow appears to be bonding well to February 1st melt/freeze crust.

Snow pack is shallow around rocks. Large grain depth hoar can be found around ridge top rocks and trees.

Travel Advisory:
Use greater caution on steeper terrain as new snow accumulates on February 3 rd melt/freeze crust. Active wind transport has been taking place during the past two days. Be wary around steep, wind loaded rocky outcrops.
