This can happen anywhere, but tornadoes are most likely to happen in the U. Tornado Alley is a nickname given to the Great Plains where tornadoes often occur. Tornadoes frequently form in this area thanks to the combination of moist, warm air from the Gulf of Mexico and cool, dry air from Canada. Tornadoes can spin at speeds over mph and cause catastrophic damage in their wake.
Tornadoes can pick up cars, blow out windows and doors, and completely flatten neighborhoods. Have you ever heard of thundersnow?
Thundersnow is a term we use to describe a thunderstorm when snow falls instead of rain. These typically happen during the winter months and are far less common than their summer counterparts. There are typically three causes of snow during a thunderstorm.
The first is a normal thunderstorm on the leading edge of a cold front or warm front. These have to form in a winter environment or run into cool air. The second reason it may snow during a thunderstorm is when a heavy synoptic snowstorm sustains strong vertical mixing. An upward motion allows for favorable conditions for lightning and thunder to occur because warm air is trying to get through the much cooler air. The last reason why thundersnow forms is due to lake effect or ocean effect thunderstorms.
Cold air passing over relatively warm water will create these types of storms. The effect commonly produces snow squalls over the Great Lakes along with the thundersnow. When a thunderstorm includes snow, lightning seems brighter as it reflects off the snow.
On the other hand, the sound of thunder is softer as the snow dampens the snow. Unfortunately, these storms can be very dangerous because they often are part of very strong winter storms. Oftentimes, thundersnow produces heavy snowfall rates in the range of 2 to 4 inches per hour.
This type of snowfall intensity limits visibility, can have tropical storm force winds, freezing temperatures, and ice accumulation. How should you stay safe during a thunderstorm? As long as you know a storm is coming, it should be relatively easy to stay safe. When storms sneak up on people is when most tragedies occur.
Keep reading this section to learn what to do before, during, and after a thunderstorm to stay safe! There is a lot you can do to prepare for a thunderstorm. Preparation is the key to safety during any severe weather event. Here are some tips for keeping thunderstorms from catching you off guard.
Be weather ready. Sign up for notifications. Some organizations have outdoor sirens while others have text alerts. Create a plan and practice. This is pretty self-explanatory. Make sure you practice. Prepare your home or place of business. Keep plants and trees trimmed, secure loose objects, close windows and doors, and move valuable objects inside. Once thunderstorms are underway, there are more things you can do to stay safe. No matter where you are, continue listening to your NOAA Weather Radio, professional meteorologists, or local authorities throughout the thunderstorm.
Avoid large open rooms, higher floors, or rooms with lots of windows. Sheds, storage facilities, tents, and overhands are not safe. Taking shelter under a tree can also be deadly, as lightning often strikes trees and wind can topple trees on top of you. If you absolutely cannot get indoors, get into a closed-top vehicle. Crouch low, with as little of your body touching the ground as possible.
You should try to drive to the closest shelter. Remember: Do not try to outrun or out-drive a tornado. What do you do after a thunderstorm? If you are injured and need medical assistance, call If you are OK, assess the damage of your home or business. Wear long pants, a long-sleeved shirt, and sturdy shoes. Contact local authorities if you see power lines down. Terms for using data resources. CD-ROM available.

It is the lightning that produces thunder in a thunderstorm. Lightning is very unpredictable, which increases the risk to individuals and property.
In the United States, 75 to people are killed each year by lightning, although most lightning victims do survive.
