A TORNADO IS A RAPIDLY ROTATING COLUMN OF AIR IN CONTACT WITH THE
GROUND. A VISIBLE CLOUD IS NOT NEEDED FOR A TORNADO TO BE IN
PROGRESS. SOME TORNADOES MAY NOT APPEAR TO EXTEND TO THE GROUND
BUT ARE CAUSING CONSIDERABLE DAMAGE. TORNADOES TAKE ON VARIOUS
SHAPES AND SIZES...AND MOST PRODUCE WINDS OF LESS THAN 120 MPH.
HOWEVER...A FEW ARE CAPABLE OF PRODUCING WINDS OVER 300 MPH. SOME
ARE VERY SMALL AND LAST FOR A FEW MINUTES...WHILE OTHERS CAN BE
ON THE GROUND FOR OVER AN HOUR...TRAVEL FOR MANY MILES...AND
POTENTIALLY REACH OVER A MILE IN WIDTH.

WHAT TO LISTEN FOR...
A TORNADO WATCH IS ISSUED BY THE NATIONAL WEATHER SERVICE WHEN
CONDITIONS ARE FAVORABLE FOR THE DEVELOPMENT OF TORNADOES IN AND
CLOSE TO THE WATCH AREA. WATCHES ARE GENERALLY ISSUED FOR THE
DURATION OF 4-8 HOURS IN ADVANCE OF THE ACTUAL OCCURRENCE OF
SEVERE WEATHER. DURING THE WATCH...PEOPLE SHOULD BE PREPARED TO
MOVE TO A PLACE OF SAFETY IF THREATENING WEATHER APPROACHES.

A TORNADO WARNING IS ISSUED BY THE NATIONAL WEATHER SERVICE WHEN
A TORNADO IS INDICATED BY RADAR OR SIGHTED BY SPOTTERS. PEOPLE IN
THE AFFECTED AREA SHOULD SEEK SAFE SHELTER IMMEDIATELY.

TORNADO EMERGENCY...
A TORNADO EMERGENCY MEANS THAT SIGNIFICANT...WIDESPREAD DAMAGE
WITH A HIGH LIKELIHOOD OF NUMEROUS FATALITIES IS EXPECTED TO
OCCUR OR CONTINUE WITH A STRONG AND VIOLENT TORNADO. A TORNADO
EMERGENCY IS NOT A NEW WARNING PRODUCT...BUT A NEW...VISIBLE AND
HIGH IMPACT CALL-TO-ACTION. THE CORRESPONDING DAMAGE TAG FOR A
TORNADO EMERGENCY IS TORNADO DAMAGE THREAT...CATASTROPHIC. FOR
MORE ABOUT IMPACT BASED WARNINGS...VISIT OUR WEBSITE AT...
WWW.CRH.NOAA.GOV/CRH/?N=2013_IBW_INFO (LOWER CASE)

TO BE READY FOR A TORNADO...HAVE A NOAA WEATHER RADIO WITH A
WARNING ALARM TONE AND BATTERY BACKUP. MAKE SURE YOUR FAMILY AND
PEOPLE IN YOUR WORKPLACE ARE FAMILIAR WITH SAFETY PRECAUTIONS AND
THE LOCATION OF A SAFE SHELTER. REVIEW YOUR TORNADO SHELTER PLANS
AND PRACTICE THEM.

IF YOU ARE IN A HOME OR OTHER BUILDING WHEN A TORNADO
STRIKES...MOVE UNDERNEATH A TABLE...WORKBENCH...OR STAIRCASE.
STAY AWAY FROM CORNERS OF THE ROOM BECAUSE DEBRIS IS USUALLY
DISPLACED INTO THOSE AREAS. STAY AWAY FROM WINDOWS.

MOBILE HOMES...EVEN IF TIED DOWN...OFFER LITTLE PROTECTION FROM
TORNADOES AND SHOULD BE ABANDONED. IF AN UNDERGROUND SHELTER IS
NOT AVAILABLE...MOVE TO THE LOWEST...MOST INTERIOR ROOM
AVAILABLE IN ANY NEARBY PERMANENT STRUCTURE.

SAFE PLACES IN AN OFFICE BUILDING...SHOPPING MALL...OR SCHOOL
INCLUDE INTERIOR HALLWAYS AND BATHROOMS. CROUCH ON THE GROUND
FLOOR AGAINST A WALL...COVERING YOUR HEAD WITH YOUR HANDS. LEAVE
WIDE OPEN ROOMS LIKE GYMS...AUDITORIUMS...OR COMMON AREAS OF
SHOPPING MALLS AS THEY ARE UNSAFE.

IF YOU ARE CAUGHT OUT IN THE OPEN OR IN A VEHICLE...NEVER TRY TO
OUTRUN A TORNADO...ESPECIALLY IF IT IS NEARBY. TORNADOES CAN MOVE
AT SPEEDS OF OVER 50 MPH AND CHANGE DIRECTIONS QUICKLY.

MANY PEOPLE MISTAKENLY THINK THAT HIGHWAY OVERPASSES PROVIDE
SAFETY FROM A TORNADO. IN REALITY...AN OVERPASS MAY BE ONE OF THE
WORST PLACES TO SEEK SHELTER FROM A TORNADO. SEEKING SHELTER UNDER
AND OVERPASS PUTS YOU AT GREATER RISK OF BEING KILLED OR INJURED
BY FLYING DEBRIS.

TORNADIC WINDS CAN MAKE THE MOST BENIGN ITEM INTO A DANGEROUS
MISSILE. IN ADDITION TO THE DEBRIS THAT CAN INJURE YOU...THE WINDS
UNDER AN OVERPASS ARE CHANNELED AND COULD EASILY BLOW YOU OR CARRY
YOU OUT FROM UNDER THE OVERPASS.
