..SUMMARY
 
 
THE NATIONAL WEATHER SERVICE IN CHARLESTON WV HAS CONFIRMED A  
MICROBURST NEAR DESPARD IN HARRISON COUNTY WEST VIRGINIA ON JUNE  
23, 2017.  
 
DAMAGE FROM THIS MICROBURST BEGAN ON THE CREST OF A RIDGE NEAR  
BEECHNUT ST. IN THE COMMUNITY OF DESPARD. INITIALLY, TREE DAMAGE  
WAS MORE SPORADIC WITH A COUPLE OF TRUNKS SNAPPED AND LARGE LIMBS  
BROKEN OUT OF THE TOPS OF TREES. ON THE DOWNWIND SIDE OF THIS  
RIDGE, AT LEAST THREE LARGE TREES WERE UPROOTED. ALSO, ONE LARGE  
TREE WAS SNAPPED SEVERAL FEET ABOVE THE GROUND. THE ORIENTATION OF  
THE FELLED TREES CLEARLY INDICATED A DIVERGENT PATTERN COMMONLY  
SEEN IN MICROBURSTS. SHINGLES WERE PEELED OFF THE ROOF OF A HOUSE  
ALONG BEECHWOOD AVE. AND SOME TREES BEHIND THIS HOUSE WERE EITHER  
SNAPPED OR UPROOTED AS THE MICROBURST BEGAN TO CREST A SECOND  
RIDGE BETWEEN BEECHWOOD AVE. AND BEECH ST.  
 
THE MOST IMPRESSIVE DAMAGE OCCURRED ALONG THE CREST OF THIS  
RIDGE, BETWEEN BEECH ST. AND HIGHLAND AVE. ONE HOUSE HAD  
APPROXIMATELY HALF OF ITS SHINGLES REMOVED AND MULTIPLE LARGE  
TREES BEHIND IT WERE SNAPPED AND/OR UPROOTED WITH FULL EXPOSURE OF  
ROOT BALLS, EACH WITH EXTENSIVE, DEEP ROOT NETWORKS. THIS IS  
LIKELY WHERE THE HIGHEST OBSERVABLE WINDS OCCURRED WITH THIS  
MICROBURST, WITH MAXIMUM SPEEDS OF AT LEAST 100 MPH. DAMAGE THEN  
BECAME VERY SPORADIC, CONSISTING OF SMALL SNAPPED LIMBS.  
 
THE NATIONAL WEATHER SERVICE IN CHARLESTON, WV WOULD LIKE TO  
SINCERELY THANK HARRISON COUNTY EMERGENCY MANAGEMENT AND THE  
PUBLIC FOR REPORTING AND HELPING SURVEY DAMAGE FROM FRIDAY'S  
STORM.

WEATHER.GOV/RLX.  
 
FOR REFERENCE:  
A MICROBURST IS A CONVECTIVE DOWNDRAFT WITH AN AFFECTED OUTFLOW  
AREA OF LESS THAN 2 1/2 MILES WIDE AND PEAK WINDS LASTING LESS  
THAN 5 MINUTES. MICROBURSTS MAY INDUCE DANGEROUS HORIZONTAL AND  
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.
