A TORNADO IS A RAPIDLY ROTATING COLUMN OF AIR THAT IS 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 DAMAGE.

TORNADOES TAKE ON VARIOUS SHAPES AND SIZES. MOST PRODUCE WINDS LESS
THAN 120 MPH. HOWEVER A FEW ARE CAPABLE OF PRODUCING WINDS OVER 200
MPH. SOME ARE VERY SMALL AND LAST FOR ONLY A MINUTE OR SO...WHILE
OTHERS CAN BE A MILE OR TWO WIDE AND STAY ON THE GROUND FOR OVER AN
HOUR.

IN WYOMING...TORNADOES HAVE OCCURRED IN EACH MONTH FROM APRIL THROUGH
SEPTEMBER...BUT ARE MOST LIKELY IN MAY AND JUNE. TORNADOES CAN OCCUR
IN ANY HOUR OF THE DAY...BUT ARE MOST LIKELY TO FORM DURING THE
AFTERNOON AND EARLY EVENING HOURS.

IF AN ACTUAL TORNADO WARNING IS ISSUED OR YOU SEE A TORNADO
APPROACHING...FOLLOW THESE SAFETY RULES:

* IF AN UNDERGROUND SHELTER IS NOT AVAILABLE...MOVE TO THE LOWEST...
  MOST INTERIOR ROOM AVAILABLE AND GET UNDER A STURDY PIECE OF
  FURNITURE IF POSSIBLE. STAY AWAY FROM WINDOWS.

* MOBILE HOMES...EVEN IF TIED DOWN...OFFER LITTLE PROTECTION FROM
  TORNADOES AND SHOULD BE ABANDONED FOR A MORE STURDY STRUCTURE.

* IF IN AN OFFICE BUILDING...SHOPPING MALL...OR SCHOOL...GO INTO AN
