Short summary
Strong winds coinciding with heavy snowfall can damage infrastructure, disrupt daily life and threaten safety. We examined how often these events occur in Finland and how long-lasting and severe they are, using reanalysis data. Such events were most common in coastal and eastern areas and usually short, while long and intense cases were rare. These events can challenge energy supply and essential services, highlighting the need to consider combined weather hazards in societal risk planning.
