As winds blow across the Sea of Japan to the west of Hakuba they will pick up a substantial amount of moisture which when it encounters the "Japanese Alps", consisting of the Akaishi, Hida, and Kiso mountain ranges, drops snow and often in large amounts and for a prolonged period. This is very likely what we could see this week (FRESH POWDER!!!), with the potential for snow squalls lasting through Wednesday (1/25). So now let’s get to the part we all want to know, snow totals, the biggest issue with this type of system is that the precipitation occurs in bands. Due to the banded nature of the squalls there are wide variations in snowfall. That being said it is quite likely that over the next couple days we will see likely see totals of 30 to 70cm with some areas flirting with +1 meter of snow. Our high resolution model is supporting this and even saying more is possible, the model is hinting at between 35 and 70cm by 2pm tomorrow (1/23), while I think this is excessive for the entire region it is quite possible that areas under persistent bands may see totals of 70cm in 36hrs. Up in Hokkaido totals will be decent across all of the island, however Kiroro will be the big winner with 36hr totals of 35-60cm likely (by 2pm 1/23) and storm totals of 40 to 75. Over the next 36 hours Niseko will receive 20-40cm, Rusutsu 15-20cm, Furano City 20-25cm, Kamui Ski Links 25-35cm, Tomamu Ski 25-35cm, Sahoro 30-40cm, and 35 to 45 on Mt Tokachi. These are fairly conservative numbers and it is possible that higher amounts will occur particularly across the higher elevations so to summarize BE EXCITED!
