Severe Weather can escalate quickly. While the possibility of tornadoes can be forecast ahead of time, they can form in minutes, day or night. Will you be prepared? Set up a way to get weather warnings any time of day. When alerted to a tornado, quickly get to a storm shelter or basement. If underground shelter isn't available, get to an interior hall away from windows.

Tornado Sheltering Guidelines: Seek the best available area immediately when a Tornado Warning is issued. Your chance of surviving a tornado is exceelent if you follow these guidelines. Worst Options: mobile homes, vehicles, underneath a highway overpass. Bad Options: Large open rooms like gymnasiums, manufactured housing. Good Options: Interior room of a well-constructed home or building, basement. Best Options: Above or below ground Tornado Storm Shelter (NSSA/ICC 500 compliant, recommended by FEMA) or a specifically-designed FEMA Safe Room.

 

Sheltering at Home

Imagine you’re relaxing at home...when all of a sudden a Tornado Warning comes through on your phone or NOAA Weather Radio. Where will you go to stay safe? #WeatherReady weather.gov/safety/tornado

Know where to go when sheltering at home from a tornado. Quickly move to your basement and bring your emergency supply kit. If you have no basement, move to an interior room with no windows. Top floors DO NOT protect you. Exterior rooms and room with windows DO NOT protect you. No place outside is safe from a tornado.

 

Tornadoes and Road Safety

Facebook
During a tornado, seeking refuge in a vehicle or under an overpass is NOT safe. If you are outside during a tornado warning, the best option is to drive to a designated shelter, basement, or safe room. weather.gov/safety/tornado

TORNADOES AND ROAD SAFETY. 1) What To Do: Get off the road. The best option is to drive to a designated shelter, basement or safe room. The next best option is a small, windowless room or hallway on the lowest floor of a sturdy building. 2) What No To Do: Do not seek refuge in a vehicle, outside or under an overpass. A highway overpass does not provide safety from a tornado. Do not seek shelter under an overpass or a tree. This puts you at greater risk of being killed or seriously injured by flying debris from the powerful tornadic winds.

 

“Particularly Dangerous Situation”

Facebook
Have you ever noticed the wording “THIS IS A PARTICULARLY DANGEROUS SITUATION” in severe weather watches? Here’s what it means.

Twitter
Have you ever noticed the wording “THIS IS A PARTICULARLY DANGEROUS SITUATION” in severe weather watches? Here’s what it means. #WeatherReady

Have you ever noticed the wording 'This is a particularly danagerous situation' in some of the severe weather watches issued by the NWS Storm Prediction Center? This wording is likely used in Tornado Watches for rare situations when long-lived and intense tornadoes are likely. This enhanced wording may also accompany Severe Thunderstorm Watches for widespread and exceptionally intense straight-line wind events. Be prepared! Review your severe weather safety procedures. Know the safest place to seek refuge ahead of time. Consider canceling or postponing outdoor activities. Have multiple ways to receive a warning. Inform others of the heightened risk.

Understanding Severe Weather Outlooks - issued by the Storm Prediction Center. 
THUNDERSTORMS (no label - winds to 40 mph / small hail): No severe thunderstorms expected. Lightning/flooding threats exist with all thunderstorms. 
1-MARGINAL (MRGL - winds 40-60 mph / hail up to 1 inch / low tornado risk): Isolated severe thunderstorms possible. Limited in duration and/or coverage and/or intensity. 
2-SLIGHT (SLGT - one or two tornadoes / reports of strong winds, wind damage / hail 1 inch in general, 2 inches isolated): Scattered severe storms possible. Short-lived and/or not widespread, isolated intense storms possible. 
3-ENHANCED (ENH - a few tornadoes / several reports of wind damage / damaging hail, 1-2 inches): Numerous severe storms possible. More persistent and/or widespread, a few intense
4-MODERATE (MDT - strong tornadoes / widespread wind damage / destructive hail, 2 inches plus): Widespread severe storms likely. Long-lived, widespread and intense
5-HIGH (HIGH - tornado outbreak / derecho): Widespread severe storms expected. Long-lived, very widespread and particulary intense.

 

What are the Hazards of Severe Weather?

Facebook
Tornadoes, large hail, strong winds, flooding, and lightning are all hazards associated with severe weather. Severe weather has been reported in all 50 states, so no matter where you are, you need to be prepared! weather.gov/safety/thunderstorm

Twitter
Severe weather can occur anywhere. Wherever you are, be prepared! weather.gov/safety/thunderstorm #WeatherReady

Understanding Severe Weather Hazards:
TORNADO - tornadoes are violently rotating columns of air that can destroy buildings and cause significant injury or death. ACTION: Take shelter immediately in a sturdy structure.
LARGE HAIL - hail can damage vehicles, crops, buildings, and cause injuries. ACTION: Move indoors away from windows.
STRONG WIND - strong wind can knock over trees and damage buildings. ACTION: Move indoors away from windows.
HEAVY RAIN - Heavy rain can cause flash flooding. ACTION: Avoid rising creeks and water-covered roads.
LIGHTNING - Lightning strikes can cause significant injury or death. ACTION: Move indoors if you hear thunder

 

Why Do Tropical Cyclones Create Tornadoes?

Facebook
Tropical cyclones spawn tornadoes when certain instability and vertical shear criteria are met, in a manner similar to other tornado-producing systems. Most landfalling tropical cyclones spawn at least one tornado. Read more about tornado science at weather.gov/jetstream/tornado

Why Do Tropical Cyclones Create Tornadoes? Instability and a strong vertical shear at low altitudes. Almost all U.S. tropical storms spawn at least one tornado.

 

Types of Tornadoes

Facebook
Supercells are not the only types of storms that develop tornadoes. Did you know that there are multiple types of tornadoes that can form? Learn all about them in the infographic below, and visit weather.gov/jetstream/tornado.

TYPES OF TORNADOES -
Supercell Tornadoes:
Tornadoes that come from a supercell thunderstorm are the most common, and often the most dangerous. A rotating updraft is a key to the development of a supercell, and eventually a tornado. There are many ideas about how this rotation begins. One way a column of air can begin to rotate is from wind shear – when winds at two different levels above the ground blow at different speeds or in different directions. Once the updraft is rotating and being fed by warm, moist air flowing in at ground level, a tornado can form.

Landspouts:
Landspouts, narrow, rope-like condensation funnels that form while the thunderstorm cloud is still growing and there is no rotating updraft. The spinning motion originates near the ground.

Waterspouts:
Waterspouts, similar to landspouts, except they occur over water.

Gustnadoes:
Gustnadoes, whirls of dust or debris at or near the ground with no condensation funnel, which form along the gust front of a storm.

Dust Devils:
A well-developed dust whirl; usually of short duration, rendered visible by dust, sand, and debris picked up from the ground. Dust devils are best developed on a hot, calm afternoon with clear skies, when intense surface heating causes large temperature differences in the lowest couple hundred feet of the atmosphere.

Fire Whirls:
Much like dust devils, the extreme heat of fires create strong updrafts, near the ground that interact with circulations in the lower atmosphere. Fire whirls are usually about 1 to 3 feet  wide and 50 to 100 feet tall.
