Last night a warm front ahead of the approaching low passed over the region. It was accommpanied by very strong winds and for a period blizzard conditions with heavy snow falling. Temperatures though remained mild, hovering around freezing and the snow is fairly wet and heavy down low. There has been significant drifting on upper slopes and although all gates are scheduled to open today (dependent on lifts) be very wary on lee slopes in the upper bowls.
Today has remained mild and the wind has abated a little but the top lifts around the resort remain on wind hold. Better quality snow will be found up higher.
A large area of low pressure has developed over East Asia and this will direct a SW airstream over Hokkaido for much of the rest of the week continuing the mild temperatures and we can expect rain from later Thursday and through Friday. Cooler temps and snow should return later on the weekend.

Avalanche Information:

Niseko Avalanche Info No.70

Moiwa base 6am: -3℃, 10cm of low pressure system snowfall during the night.
Coastal data: W10m/s at Benkei cape, WSW11m/s, 1.6m waves and 1013 hPa at Kamui cape.
Annupuri peak data: SSW30.5m/s at 22:30, WSW8.8m/s and -8℃ at 6am, forecasted wind at noon W20m/s.
Drastic development of snowdrifts in leeward slopes above 800m (up to 50cm at 1000m) due to the passing cold front.
Considerable hazards of hard slab avalanches will persist this morning in Higashi-One steeps, Backbowl 1000m area, Mikaeri no sawa area, western slopes of the north face. Potential trigger layer is Feb 22nd.
Peak gates are scheduled to open at 10:00. Follow the ski patrol’s instructions.
It is strongly recommended to avoid riding knolls, crusted/wind-rippled 40°slopes or widely open slopes all at once. Ride one by one, strong stimulation could trigger a major scale slide from deeper layers.
Avalanches DO happen here, don’t be mislead by spurious information that there are no avalanches in Niseko.
There have been 9 avalanche related fatalities between 1985 and 1999 in Niseko.
Always reconsider the risk you’re taking before stepping out of bounds.
Beware also of crevasses and trees.
