NATIONAL WEATHER SERVICE PERSONNEL HAVE SURVEYED DAMAGE IN  
MCMINNVILLE...LOCATED IN YAMHILL COUNTY OREGON. THE SURVEY TEAM 
DETERMINED THAT A SHORT LIVED TORNADO OCCURRED IN MCMINNVILLE.

THE MCMINNVILLE TORNADO BEGAN NEAR A HOME ON THE SOUTHWEST 
INTERSECTION OF 14TH AVE AND KIRBY. AT THIS LOCATION SEVERAL 8-10 
INCH DIAMETER TREES WERE SNAPPED WITH DEBRIS TOSSED BOTH SOUTHEAST 
AND NORTHWEST OF THE LOCATION. THE DAMAGE IN THIS AREA WAS 
CONSISTENT WITH EF-0 DAMAGE. THE TORNADO CONTINUED SOUTHEAST FOR ONE 
BLOCK THROUGH A RESIDENTIAL NEIGHBORHOOD WITH SOME TREE DAMAGE NOTED.

THE MAXIMUM DAMAGE OCCURRED AS THE TORNADO CROSSED THE RAILROAD 
TRACKS NEAR 12TH AVE AND ENTERED AN INDUSTRIAL DISTRICT. A CAMPER 
WAS LIFTED OFF OF A PICKUP TRUCK AND THROWN OVER A CHAIN LINK FENCE 
TO THE NORTHWEST...OPPOSITE THE DIRECTION THE STORM WAS MOVING. A 
LARGE METAL INDUSTRIAL BUILDING HAD MUCH OF ITS ROOF STRUCTURE TORN 
OFF. 300 POUND TRELLISES WERE LOFTED...WITH SOME WOOD DEBRIS 
BECOMING IMPALED VERTICALLY INTO A MOBILE HOME. THIS EF-1 DAMAGE WAS 
CONSTRAINED TO ABOUT A 1 SQUARE BLOCK RADIUS BOUNDED BY NE 12TH 
AVE...NE 11TH WAY...NE ALPINE AVE...AND A RAILROAD. THE TORNADO 
PROCEEDED TO DO ADDITIONAL EF-0 DAMAGE TO 1-2 INDUSTRIAL BUILDINGS 
LOCATED BETWEEN ALPINE AND LAFAYETTE AVENUES.

DEBRIS WAS THROWN ACROSS LAFAYETTE AVENUE TOWARD AN AUTO REPAIR 
SHOP...AND THERE WAS DAMAGE TO A STRUCTURE HOLDING UP A SIGN AND 
SOME TREES NEAR THE SHOP. THE TORNADO LIFTED ON THE SE SIDE OF THE 
INTERSECTION OF 11TH AVE AND LAFAYETTE. DEBRIS CONTINUED TO BE 
THROWN ALONG THE STORMS SW MOVING PATH THROUGH A RESIDENTIAL 
NEIGHBORHOOD. THE STORM ENTERED JOE DANCER PARK...WHERE STRAIGHT 
LINE WIND DAMAGE WAS NOTED.  THE DAMAGE WAS WIDELY SCATTERED AND 
CONSISTENT WITH MAINLY 60-80 MPH WINDS. THIS INCLUDED ABOUT A HALF  
DOZEN MEDIUM-SIZED DECIDUOUS TREES SNAPPED IN THE DIRECTION OF STORM
