In addition to poor visibility and heavy snowfall, which of the following defines blizzard conditions?

Blizzard conditions are characterized by a combination of heavy snowfall and strong winds, which significantly reduce visibility and create harsh winter weather. The correct answer highlights that wind speeds greater than 35 mph are a crucial element of blizzard criteria.

When winds reach this level, they can cause significant blowing and drifting of snow, worsening visibility even further and potentially leading to life-threatening situations. This level of wind speed creates dangerous conditions that distinguish a blizzard from other winter weather phenomena like snowstorms, which may not have the same intensity of wind.

While other factors such as low temperatures or higher humidity may contribute to the overall winter weather experience, they do not define blizzard conditions in the same critical way as strong winds. In fact, temperatures can vary in blizzard conditions, and humidity, though it may impact precipitation, is not a defining characteristic of a blizzard. Thus, it is the wind speed, reaching or exceeding 35 mph, that is essential for classifying a storm as a blizzard.
