Both convective and orographic (stau effect) snowfall are ongoing across the western Alps, particularly the extreme NW Italy, under the effects of the ongoing intense cold core upper low over the western Mediterranean. Various high-resolution models indicate 100 cm of additional snowfall by late tomorrow, with some areas receiving even up to twice as much.
