BlizzardsAsna Rizwan

Blizzards are dangerous winter storms that are a combination blowing snow and wind resulting in very low visibilities

Blizzards meet the following conditions:1. Wind speeds over 50 mph2. Whiteout condition snow3.Below freezing temps (27F or lower)

Power outages can occur due to strong winds and heavy snow. Pipes can freeze and regular fuel sources may be cut off.

When a blizzard is in the forecast, you may receive a “Winter Storm Watch," which means there is a possibility of a storm taking effect. You could also receive a “Winter Storm Warning," which means a storm is on the way or already taking place.

Blizzards are usually formed when the jet stream pitches very far south. This allows the cold air that comes from the north to collide with warm air coming from the south. This creates a strong storm.

What Are Blizzards?

What Causes a Blizzard

Watches & Warnings

Blizzards, because of its cold weather can cause Frostbite and Hypothermia. Frostbite is a severe reaction to cold. Hypothermia is when the body temperature is extremely low.

Effect of a Blizzard

Blizzards make driving extremely hazardous. Driving is difficult because of the whiteout conditions and drifting snow. Many people die due to car accidents.

Will blizzards become more frequent in the future as a response to climate change? That's difficult to know for sure,but warming oceans may increase the contrast between warm, coastal air and cooler air over land, which could increase the frequency of storms.
