SURVEY SUMMARY: A TORNADO INITIALLY TOUCHED DOWN JUST SOUTH OF
BROW ROAD IN NORTHERN ETOWAH COUNTY…ABOUT 4 MILES EAST OF SARDIS
CITY…SNAPPING AND UPROOTING MANY TREES. THE TORNADO RAPIDLY
INTENSIFIED AS IT TRACKED NORTHEAST AND CROSSED LIBERTY HILL
AND HORTON GAP ROADS. SEVERE DAMAGE OCCURRED ALONG LIBERTY HILL
ROAD WHERE A HOME WAS LIFTED OFF ITS BLOCK FOUNDATION AND MOVED
ABOUT 60-80 FEET FROM ITS ORIGINAL LOCATION. DESPITE THIS…MOST
OF THE EXTERIOR WALLS /AND EVEN A PORTION OF THE ROOF/ REMAINED
INTACT. NUMEROUS TREES AROUND THIS PROPERTY WERE SNAPPED NEAR THE
BASE INDICATING VERY STRONG WINDS. JUST WEST OF THIS LOCATION…
SEVERAL MANUFACTURED HOMES/TRAILERS WERE COMPLETELY DESTROYED. TWO
OTHER HOMES SUSTAINED SIGNIFICANT ROOF LOSS AND EXTERIOR WALL DAMAGE.
ALONG HORTON GAP ROAD…A TWO-STORY HOME WAS DESTROYED WITH JUST A
FEW INTERIOR WALLS LEFT STANDING. MUCH OF THE DEBRIS WAS THROWN
SEVERAL HUNDRED YARDS AWAY FROM ITS ORIGINAL LOCATION AND TREES WERE
LITERALLY RIPPED OUT OF THE GROUND AND THROWN. JUST NORTHEAST OF THIS
LOCATION…A LARGE WOOD-FRAMED CHICKEN HOUSE WAS DESTROYED.

AT THESE LOCATIONS…THE TORNADO WAS AT ITS PEAK INTENSITY WITH
WINDS ESTIMATED BETWEEN 135 AND 155 MPH…GIVING IT A RATING OF
EF-3.

ON EITHER SIDE OF THE CENTER LINE TRACK…DAMAGE WAS SEEN ALONG
OWENS ROAD /WEST OF THE TRACK/ AND RODEN ROAD /EAST/. STRUCTURAL
DAMAGE RESULTING IN LOSS OF ROOF AND EXTERIOR WALLS/SIDE PANELS WAS
SEEN ALONG WITH NUMEROUS TREES SNAPPED OR UPROOTED. THE TORNADO CROSSED
VERY NEAR WHERE THE RODEN AND OWENS ROADS INTERSECT…JUST SOUTH
OF THE ETOWAH/DEKALB COUNTY LINE.

THE TORNADO CONTINUED TO BE STRONG /EF-2 INTENSITY/ AS IT CROSSED INTO
DEKALB COUNTY. JUST SOUTH OF WHERE CR 4 AND 450 MEET…A MANUFACTURED
HOME WAS COMPLETELY DESTROYED. THE UNDERCARRIAGE WAS SO BADLY
MANGLED AND TWISTED UP…IT WAS NEARLY UNRECOGNIZABLE. TREES WERE ALSO
DEBARKED AT THIS LOCATION.

WHERE CR 4/450 AND 455 MEET…A SINGLE-STORY HOME WAS HEAVILY
DAMAGED AND SHIFTED OFF ITS FOUNDATION. NEARLY THE ENTIRE ROOF WAS
LIFTED. THE TORNADO CONTINUED TO PRODUCE DAMAGE AS IT TRACKED
NORTHEAST…CROSSING CR 25. THE TORNADO WAS AT LEAST 1/4 MILE WIDE
AT THIS POINT WITH NOTICEABLE DAMAGE SEEN ALONG CR 4 /EAST OF THE
CENTER TRACK/ AND CR 455 /WEST OF THE TRACK/. THE TORNADO THEN TOOK
A SLIGHT JOG TO THE NORTH AND CROSSED CR 457 AND 29 WHERE SEVERAL
HOMES SUSTAINED SIGNIFICANT LOSS OF ROOF COVERING/SHINGLES AND TREES
WERE EITHER SNAPPED OR UPROOTED. THE TORNADO APPEARED TO ENTER A
WEAKENING PHASE AT THIS POINT. ON THE WEST SIDE OF THE TRACK…
A SMALL FARM OUTBUILDING COLLAPSED AND A LARGE OAK TREE FELL ON
TOP OF A HOME ALONG CR 29. TREES WERE EITHER UPROOTED OR SNAPPED
ALONG CR 1920. THE TORNADO CROSSED CR 4 AGAIN /JUST NORTH OF CR 1920/
AND APPROACHED THE HIGHER TERRAIN/RIDGETOP AREA WEST OF DUGOUT AND
LITTLE SAND VALLEY. TREES WERE SEEN SNAPPED OR UPROOTED. A BARN WAS
DESTROYED ALONG CR 4…JUST SOUTH OF COAL CREEK. THE TORNADO HAD
NARROWED SIGNIFICANTLY BY THIS POINT BUT WAS STILL PRODUCING WINDS
BETWEEN 80-90 MPH.

NEARING THE END OF ITS LIFE…THE TORNADO CROSSED HIGHWAY 227 OVER
THE HIGHER TERRAIN…SNAPPING AND UPROOTING A NARROW CORRIDOR OF
TREES. JUST NORTH OF HIGHWAY 227…ALONG CR 12 JUST NORTH OF HAYES
GAP…ADDITIONAL TREES WERE SNAPPED. THIS MATCHED UP FAIRLY WELL
WITH THE DIMINISHING RADAR DEBRIS SIGNATURE AND BROADENING CICRULATION
DEPICTED BY RADAR VELOCITY PRODUCTS. NO ADDITIONAL/DEFINITIVE DAMAGE
WAS SEEN NORTH OF THIS LOCATION…THEREFORE THE PRELIMINARY ‘END
POINT’ IS PLACED IN THE HIGHER TERRAIN JUST NORTH OF CR 12 AND WEST
OF CR 221 IN SOUTHERN DEKALB COUNTY…ABOUT 4 MILES SOUTHEAST OF
CROSSVILLE.
