What's a Blizzard?

Facebook
Did you know not all blizzards involve falling snow? By definition, a blizzard includes 35+ mph winds that cause blowing snow, reducing visibility to 1/4 mile or less for at least 3 hours. If the visibility reduction comes from snow that has already fallen, it is called a ground blizzard. Whether or not the snow falls during the time of the blizzard, dangerous conditions can result. Make sure you’re prepared! weather.gov/winter

What's a Blizzard? Blowing snow, 35+ mph winds, less than 1/4 mile visibility, for 3+ hours. Did you know that falling snow isn't necessary for a blizzard? A blizzard that results from previously fallend snow is called a ground blizzard.

 

Upslope Snow

Facebook
Have you wondered why the windward side of mountains or large hills receives so much more snow than surrounding areas? This is due to upslope snow. When moist wind blows against the side of mountains/hills, the air is forced to rise (called orographic lift). As the air rises and cools, water vapor condenses, resulting in clouds and precipitation over the windward region. Conversely, the leeward side often receives less snow due to descending air.

Why does the windward side of mountains or large hills receive so much more snow than surrounding areas? It’s because of the upslope effect. When you’re in one of these windward areas, make sure you’re #WeatherReady

Upslope Snow: 1) When wind blows against mountains or hills, it is forced to rise. This is called orographic lift. 2) As moist air rises and cools, water vapor condenses, resulting in clouds and precipitation. 3) This results in the windward sides of mountains and hills receiving more snow than surrounding areas in the winter.

Science of Snowflakes

Facebook
Did you know that while no two snowflakes are exactly the same, they are all six-sided? Snowflakes’ hexagonal shapes are due to the molecular structure of ice. Learn more about the science behind snowflakes: noaa.gov/stories/how-do-snowflakes-form-science-behind-snow

Winter Driving

Facebook
Winter driving can be hazardous. One simple way to keep yourself and everyone on the road safe is to slow down. Remember, “Ice and snow, take it slow”. Learn more at weather.gov/winter

Do your part to keep everyone safe on the roads this winter. Learn more at weather.gov/winter #WeatherReady

Ice and Snow, Take it Slow. 70% of snow and ice-related injuries occur in automobiles. Leave extra space between you and the vehicle in front of you.

 

What Causes Winter?

Facebook
Did you know that in the northern hemisphere, winter actually occurs when the Earth is closest to the Sun? This is possible because of the way the Earth tilts on its axis. During winter, the northern hemisphere is tilting away from the Sun, causing the Sun’s rays to hit the northern hemisphere at a lower angle, which results in far lower temperatures.

Winter and Pets

Don't forget your pets - bring them indoors. Make sure they have a warm dry place with plenty of food and water.

 

Science of Wind Chill

Facebook
Extremely cold air affects millions of people across the United States every winter, and even into parts of the spring. This Arctic air, together with brisk winds, can lead to dangerously cold wind chill values, which can cause your body to lose heat quickly. weather.gov/safety/cold-wind-chill-chart

Twitter
Arctic air, together with brisk winds, can lead to dangerously cold wind chill values. weather.gov/safety/cold-wind-chill-chart

Infographic - The Science of Wind Chill. The average temperature of the human body is 98.6 degrees fahrenheit. Under calm conditions, the body radiates heat, creating a layer of warmth between or skin and the cold surroundings. But when it's windy, the moving air breaks up this insulating layer. It speeds up heat loss by whisking away the warmth from our skin. Hypothermia begins when our body temperature drops two to four degrees.

 

Winter Injuries and Fatalities

Facebook
Slippery sidewalks and roads aren’t the only things to look out for in late winter and early spring snow storms. Shoveling snow can be a health risk as well. Remember to stay hydrated, take frequent breaks, and move only small amounts with each shovel pass. Learn more at weather.gov/winter

Twitter
Shoveling snow can be a health risk, so remember to take it easy. Learn more at weather.gov/winter #WeatherReady

Shovel smart! Shoveling heavy, wet snow can put a big strain on the heart. Stay hydrated and take frequent breaks. Only move small amounts with each shovel pass.

 

Winter Precipitation

Will there be rain, ice or snow? This graphic explains how having different layers of warm and cold air between the clouds and the ground determines the type of precipitation that hits the ground. nssl.noaa.gov/education/svrwx101/winter/types/

Winter’s Fury: Nor’easters

Facebook
Not many winter storms have the potential to bury 100 million people in 1-2 feet of snow in a single day. Nor’easters are notorious for packing strong winds and copious amounts of moisture they get from the Atlantic. The heavily populated region between Washington D.C., Philadelphia, New York City, and Boston -- the “I-95 Corridor” -- is especially impacted by Nor’easters. weather.gov/safety/winter-noreaster

Snow Water Cycle

Facebook
During winter months, falling snow serves as an important source of fresh water across the world. When spring arrives, melting snow helps replenish rivers, lakes, and reservoirs. The melting snow adds much-needed moisture to the soil and helps refill underground aquifers, which are vital for growing crops and for drinking water. weather.gov/jetstream/hydro

Snow Water Cycle: The hydrologic cycle involves the continuous circulation of water in the Earth-Atmosphere system. At its core, the water cycle is the motion of the water from the ground to the atmosphere and back again. During the winter months, falling snow serves as an important source of fresh water across the world. When spring arrives, melting snow helps replenish rivers, lakes and reservoirs. The melting snow adds much needed moisture to the soil and helps refill underground aquifers, which are vital for growing crops and for drinking water.

Cold: 2-3 layers; warm hat; gloves; outer layer to keep out wind, wet snow; 1-2 long layers on legs; boots (water-proof). Extreme cold: 3+ layers (1 insulating); warm hat; face mask; gloves; outer layer to keep out wind; 2+ long layers on legs; boots (water proof).

Winter Storm Advisory, Watch, and Warning

Facebook
Do you know the difference between a Winter Storm Watch, Winter Storm Warning, and a Winter Weather Advisory? When a warning is issued: TAKE ACTION! When a watch is issued: Get Prepared! When an advisory is issued: Take Precautions! Find out more at: weather.gov/safety/winter-ww

Twitter
What’s the difference between a Winter Storm Watch and a Winter Storm Warning? weather.gov/safety/winter-ww #WeatherReady

Winter Storm Products: 1) Winter Storm Warning: Snow, sleet or ice expected! Take Action! Confidence is high that a winter storm will produce heavy snow, sleet or freezing rain and cause signficiant impacts. 2) Winter Storm Watch - Snow, sleet, or ice possible! Be prepared. Confidence is medium that a winter storm could produce heavy snow, sleet, or freezing rain and cause significant impacts. 3) Winter Storm Advisory - Wintry weather expected. Exercise caution. Light amounts of wintry precipitation or patchy blowing snow will cause slick conditions and could affect travel if precautions are not taken.
