BEFORE THE EXTERIOR WALLS COLLAPSED. TWO PERSONS TOOK SHELTER INSIDE 
THE BUILDING JUST BEFORE THE STORM HIT...AND FORTUNATELY EMERGED 
UNHARMED. THE ROOF OF THE BUILDING WAS LIFTED AND BLOWN 
APPROXIMATELY 100 YARDS. A SNAPPED POWER POLE APPEARED TO BE THE 
RESULT OF THE AIRBORNE ROOF. THE DAMAGE PATTERN INDICATES THAT IT

FOR REFERENCE...

OF LESS THAN 2 1/2 MILES WIDE AND PEAK WINDS LASTING LESS THAN
5 MINUTES. MICROBURSTS MAY INDUCE DANGEROUS HORIZONTAL/VERTICAL
WIND SHEARS...WHICH CAN ADVERSELY AFFECT AIRCRAFT PERFORMANCE AND
CAUSE PROPERTY DAMAGE. STRAIGHT-LINE WINDS ARE GENERALLY ANY WIND
THAT IS NOT ASSOCIATED WITH ROTATION...USED MAINLY TO DIFFERENTIATE
THEM FROM TORNADIC WINDS.
