...SUMMARY...
THE NATIONAL WEATHER SERVICE IN WILMINGTON OH HAS CONFIRMED A
MICROBURST /STRAIGHT LINE WIND DAMAGE/ NEAR WAYNESVILLE IN WARREN
COUNTY OHIO ON JUNE 19TH 2014.

A DAMAGE SURVEY COMPLETED BY THE NATIONAL WEATHER SERVICE IN COLLABORATION
WITH WARREN COUNTY EMERGENCY MANAGEMENT AND LOCAL LAW ENFORCEMENT FOUND
THUNDERSTORM WIND DAMAGE BEGINNING NEAR THE INTERSECTION OF PRESTON DRIVE AND LYTLE
ROAD...FANNING OUT TO THE EAST-NORTHEAST ALONG AND TO THE NORTH OF PRESTON
DRIVE...WEST OF OLD STAGE ROAD AND THEN ACROSS BELLBROOK ROAD...ENDING ON
OLD STAGE ROAD NORTHEAST OF WAYNESVILLE.

THE DAMAGE WAS LARGELY CONFINED TO TREES AND POWER POLES...WITH NUMEROUS HEALTHY
HARDWOOD TREES AND BRANCHES SNAPPED...MOST HIGH /20 TO 25 FEET/ ABOVE THE GROUND.
NINE POWER POLES ALONG THE WEST SIDE OF BELLBROOK ROAD WERE TOPPLED...LYING EAST.
MUCH OF THE TREE DAMAGE WAS BLOWN TO THE EAST AS WELL. ONE TREE LANDED ON A HOME
CAUSING MINOR STRUCTURAL DAMAGE.

THE RELATIVELY SMALL AREA OF INITIAL DAMAGE...FANNING TO A MUCH LARGER DAMAGE

WEATHER.GOV/ILN.

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/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.
