...SUMMARY...
THE NATIONAL WEATHER SERVICE IN WILMINGTON OH HAS CONFIRMED A
MICROBURST /STRAIGHT LINE WIND DAMAGE/ NEAR WARSAW IN GALLATIN
COUNTY KENTUCKY ON JULY 7 2014.

DAMAGE WAS FIRST OBSERVED BY THE NWS ASSESSMENT TEAM AT A 
LARGE OPEN STRUCTURE ALONG US ROUTE 42 APPROXIMATELY 0.4 MILES 
SOUTHWEST OF THE INTERSECTION WITH 4TH STREET IN WARSAW. THE 
STRUCTURE MEASURED APPROXIMATELY 100X50 FEET AND 40 FEET TALL 
WITH OPEN PASSAGES ON THE NORTH AND SOUTH SIDES. MUCH OF THE 
SIDING AND WOODEN SUPPORT STRUCTURE WAS REMOVED ON THE WEST 
SIDE...THOUGH THE OPENNESS OF THE STRUCTURE LIKELY RENDERED 
IT SUSCEPTIBLE TO THIS TYPE OF DAMAGE FROM STRONG WINDS.

DAMAGE WAS NEXT OBSERVED TO ANOTHER STRUCTURE ALONG US ROUTE 
42 APPROXIMATELY 0.2 MILES SOUTHWEST OF THE INTERSECTION WITH 
4TH STREET IN WARSAW. THE STRUCTURE HAD A FLAT ROOF FROM 
WHICH A FLEXIBLE MEMBRANE AND SEVERAL PERIMETER TILES WERE 
REMOVED BY THE WIND. THESE ROOF COMPONENTS WERE DEPOSITED ON 
THE GROUND BESIDE THE WALLS OF THE STRUCTURE.

THE TEAM THEN MOVED INTO RESIDENTIAL AREAS IN THE SOUTHWEST 
PORTION OF WARSAW AND NOTED BROKEN TREE LIMBS AT SEVERAL 
LOCATIONS. THESE LIMBS WERE MOSTLY 1-3 INCHES IN DIAMETER.

MORE SIGNIFICANT TREE DAMAGE WAS FOUND ALONG PARK AVENUE IN 
WARSAW WHERE ONE APPARENTLY HEALTHY OAK TREE WITH A TRUNK 
DIAMETER OF APPROXIMATELY 15 INCHES WAS SNAPPED OFF 
10 FEET ABOVE THE GROUND. ANOTHER NEARBY TREE WITH A TRUNK 
DIAMETER OF APPROXIMATELY 10 INCHES WAS UPROOTED. SIMILAR 
TREE DAMAGE WAS FOUND NEAR THE INTERSECTION OF STAFFORD 
CIRCLE AND 1ST STREET IN WARSAW. A STAND OF AT LEAST 4 
TREES ALONG BEECHWOOD CIRCLE HAD NUMEROUS LIMBS 8-12 INCHES 
IN DIAMETER BROKEN. ONE OF THESE LIMBS CUT THROUGH MOST OF 
THE VERTICAL LENGTH OF A MOBILE HOME WALL WHEN IT FELL. A 
LOCAL NEWS STATION REPORTED THAT A RESIDENT IN THIS MOBILE 
HOME SUSTAINED A MINOR HEAD LACERATION WHEN THIS DAMAGE 
OCCURRED. ANOTHER TREE NEAR PARK ROAD WITH A TRUNK DIAMETER 
OF APPROXIMATELY 15 INCHES WAS SNAPPED ABOUT 4 FEET ABOVE 
THE GROUND.

THE EASTERN EXTENT OF THE MICROBURST WAS ALSO MARKED BY 
DAMAGE AT GALLATIN HIGH SCHOOL. A ROOF AIR CONDITIONER 
UNIT WAS LIFTED FROM THE ROOF...THEN DROPPED BACK DOWN. 
CRACKS IN THE SURROUNDING ROOF STRUCTURE RESULTED WHEN 
THE UNIT WAS DROPPED. THE NEARBY ATHLETIC FIELDS ALONG 
DORMAN DRIVE SUSTAINED DAMAGE TO THE BLEACHERS AND 
FENCES. AT LEAST TWO SETS OF BLEACHERS WERE MOVED OR 
DESTROYED...AND MUCH OF THE BASEBALL OUTFIELD FENCE 
IMMEDIATELY BESIDE DORMAN DRIVE WAS PARTIALLY FLATTENED 
WITH SOME METAL SUPPORTING POLES BENT TO A 90 DEGREE 
ANGLE AT THE GROUND. THE FENCE WAS COVERED WITH A 
SEMI-PERMEABLE MATERIAL THAT ALLOWED SOME AIR TO PASS 
THROUGH...THOUGH THIS COVERING LIKELY INCREASED THE 
DAMAGE GIVEN SUCH STRONG WINDS.

RESIDENTS INTERVIEWED AT SEVERAL POINTS DURING THE 
SURVEY MENTIONED THE EXTREMELY HEAVY RAIN THAT 
ACCOMPANIED THE DAMAGING WINDS. THIS LENDS FURTHER 
EVIDENCE TO THE OPINION THAT THIS DAMAGE RESULTED 
FROM THE WINDS OF A MICROBURST. DEBRIS WAS ALSO 
FOUND TO BE GENERALLY DEPOSITED TOWARDS THE SOUTH 
AND EAST...WHICH IS CONSISTENT WITH THE DIRECTION 
OF STORM MOTION ASCERTAINED FROM RADAR AT THAT 
TIME.

THANKS ARE EXTENDED TO THE GALLATIN COUNTY EMA AND 
THE STATE OF KENTUCKY EMA FOR THEIR ASSISTANCE TO 
THIS SURVEY.

THIS INFORMATION CAN ALSO BE FOUND ON OUR WEBSITE AT
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.
