📚 What is a Snowstorm?
A snowstorm is a weather event characterized by falling snow. It can range from a light dusting to heavy snowfall and can be accompanied by wind.
- ❄️Definition: Precipitation in the form of snow falling from the sky.
- 🌡️Temperature: Temperatures are typically at or below freezing (0°C or 32°F).
- 💨Wind: May involve wind, but not necessarily strong or sustained.
- Duration: Can last for a few hours to several days.
❄️ What is a Blizzard?
A blizzard is a severe snowstorm characterized by strong sustained winds, heavy snowfall, and reduced visibility. It's more than just a lot of snow; it's a specific combination of conditions that make travel and being outdoors extremely dangerous.
- 🌬️Definition: A severe snowstorm with strong, sustained winds and low visibility.
- 📉Visibility: Visibility is reduced to less than 1/4 mile (0.4 km).
- 💨Wind: Sustained winds of 35 mph (56 km/h) or greater.
- Duration: These conditions must last for at least 3 hours.
