  2. Blizzard Facts • A blizzard is a severe winter storm that meets these requirements: • It must have winds of at least 35 miles per hour • It also must have visibility reduced to ¼ of a mile or less due to snow for at least 3 hours. • Temperatures of 20 degrees Fahrenheit or lower. • It does not have to actually have to be snowing for a blizzard to occur, it can also just blow around snow already on the ground. • This is called a ground blizzard.

  3. Blizzard Facts • A severe blizzard is a blizzard that meets the following requirements: • Winds of at least 45 miles per hour. • 0 visibility due to snow. • Temperatures of 10 degrees Fahrenheit or less. • Blizzards are more likely to occur in plains or other places without much obstructions.

  4. Blizzard Causes • Blizzard conditions often develop on the northwest side of an intense storm system because the difference between in the lower pressure storm and the higher pressure to the west creates a tight pressure gradient, which in turn results in very strong winds. • These strong winds combine with falling snow and fallen snow to create blizzards and whiteout conditions. • The strongest blizzards often form when the blizzard dips south and clashes with warmer air, causing more winds.

  5. Blizzard Dangers • The extremely low visibility caused by snow makes it almost impossible to do anything outside, such as driving a car. • The extremely low temperatures can cause frostbite and hypothermia, and can freeze water pipes. • The high winds can knock trees and telephone poles over. • Gas and electricity can be knocked out. • All of these plus the snow on the ground can make communication and rescue nearly impossible.

  6. Blizzard Safety • During a blizzard, it is safest to stay inside at all times. • If you must go outside, make sure to cover exposed skin and keep warm. • If you are traveling and a storm becomes a blizzard or you drive into a blizzard, you should stop immediately and find somewhere safe. • Make sure to always have emergency supplies in the winter season just in case. • Always be prepared for a power outage by having candles and pre-charged or manually chargeable flashlights.
