Tornado Sheltering Guidelines: Seek the best available refuge area immediately when a Tornado Warning is issued. Your chance of surviving a tornado is excellent if you follow these guidelines. BEST OPTIONS: 1)Above or below ground Tornado Storm Shelter (NSSA/ICC 500 compliant). 2)Specifically-designed FEMA Safe Room. FEMA recommends either of these options. GOOD OPTIONS: 1)Interior room of a well-constructed home or building. 2)Basement. BAD OPTIONS: 1)Large open rooms like gymnasiums. 2)Manufactured housing. WORST OPTIONS: 1)Mobile homes. 2)Vehicles. 3)Underneath a highway overpass.
TORNADO TERMINOLOGY 1) Tornado Watch: Weather conditions could lead to the formation of severe storms and tornadoes. Be prepared! Know your safe location. Be ready to act quickly if a Warning is issued or you suspect a tornado is approaching. 2) Tornado Warning: A tornado has been spotted or indicated by weather radar, meaning a tornado is occurring or expected soon. Take Action! There is imminent danger to life and property. Immediately seek refuge in the safest location possible. 3) Tornado Emergency: An exceeding rare situation with a severe threat to human life and catastrophic damage due to a confirmed violent tornado. Take Action! Immediately seek refuge in the safest location possible.
Have you ever noticed the wording THIS IS A PARTICULARLY DANGEROUS SITUATION in some of the severe weather watches issued by the NWS Storm Prediction Center? This wording is used in Tornado Watches for rare situations when long-lived and intense tornadoes are likely. This enhanced wording my 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.
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.
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.
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.
