Additional Details
A strong low-pressure system is responsible for this storm. Initial snowfall tonight may reach up to 10 cm. Conditions may ease slightly this evening, but freezing drizzle is possible in some areas.
By Sunday morning, expect poor conditions as heavier snow moves in, with an additional 15 to 25 cm expected. Travel is not recommended, especially on Sunday, due to the hazardous conditions.
