...RESULTS OF THE SURVEY OF THE COOKE COUNTY STORM DAMAGE...

THIS MORNING...STAFF FROM THE NATIONAL WEATHER SERVICE
IN FORT WORTH CONDUCTED A SURVEY OF THE DAMAGE IN COOKE COUNTY.
BASED ON THEIR STUDY OF THE STORM TRACK...IT APPEARS THAT A STRONG
DOWNBURST DEVELOPED AND MOVED ACROSS THE COUNTY.

DAMAGE ACROSS THE COUNTY COVERED A SWATH FROM NORTHEAST OF ERA TO
EAST OF GAINESVILLE. EARLY IN THE SWATH...NORTHEAST OF THE HOOD
COMMUNITY...DAMAGE WAS CONFINED MAINLY TO TREE LIMBS. AS THE STORM
APPROACHED LINDSAY...A SWATH OF MORE SIGNIFICANT WINDS REACHED THE
GROUND. SIGNIFICANT DAMAGE TO MOBILE HOMES AND OUTBUILDINGS WAS
NOTED. THE WINDS DOWNED TREES AND CAUSED ROOF DAMAGE TO PERMANENT
STRUCTURES.

FROM THE GAINESVILLE AIRPORT TO NEAR INTERSTATE 35...
SEVERAL METAL INDUSTRIAL BUILDINGS AND AIRPORT HANGARS WERE
DAMAGED...SOME EXTENSIVELY. THE ROOF OF A MOTEL WAS BLOWN OFF JUST
WEST OF INTERSTATE 35...AND THE PORCH OF A MOTEL JUST EAST OF THE
INTERSTATE WAS REMOVED.

AS THE STORM MOVED ACROSS GAINESVILLE...SCATTERED WIND DAMAGE
CONTINUED. TREE AND ROOF DAMAGE WAS NOTED EAST OF THE
INTERSTATE. ALSO AT THIS TIME...GIANT HAIL FROM THE STORM BEGAN
REACHING THE GROUND. BASEBALL SIZED HAIL DAMAGED VEHICLES ON THE EAST
SIDE OF TOWN. GIANT HAIL AND AREAS OF WIND DAMAGE CONTINUED NEAR AND
NORTH OF HIGHWAY 82 EAST OF GAINESVILLE.

IN THE WIND SWATH...WIND SPEEDS WERE GENERALLY IN THE 60 MILE PER
HOUR RANGE. HOWEVER...IN THE AREAS OF MORE SUBSTANTIAL DAMAGE FROM
LINDSAY TO INTERSTATE 35...WINDS MAY HAVE LOCALLY GUSTED TO 90 MPH.

THE TYPE OF STORM WHICH PRODUCED THIS DAMAGE IS KNOWN AS A HIGH
PRECIPITATION SUPERCELL. HIGH PRECIPITATION...OR HP...SUPERCELLS
HAVE A REPUTATION FOR PRODUCING EXTREMELY LARGE HAIL AND DAMAGING
DOWNBURSTS. HP SUPERCELLS HAVE SPAWNED DEVASTATING THUNDERSTORM
EVENTS IN NORTH TEXAS...INCLUDING THE JUNE 1 2004 STORM WHICH KNOCKED
OUT POWER TO HUNDREDS OF THOUSANDS OF PEOPLE...AND THE MAY 5 1995
STORM WHICH WAS ONE OF THE MOST DAMAGING SINGLE-THUNDERSTORM EVENTS
IN U.S. HISTORY.

wow...90mph wind gusts is like going through a TS or Cat. 1 hurricane. I am glad no one was killed since this was so sudden.

[HurricaneHunter914]

90 mph wind gusts would cause me to run outside.

WEST OF HIGHWAY 64. NUMEROUS TREES AND LARGE TREE LIMBS WERE DOWNED
IN A NEIGHBORHOOD EAST OF HIGHWAY 19 AND NORTH OF HIGHWAY 243. THE

...RESULTS OF THE SURVEY OF THE MCLENNAN COUNTY STORM DAMAGE...

THIS AFTERNOON AND EVENING...STAFF FROM THE NATIONAL WEATHER SERVICE
IN FORT WORTH CONDUCTED A SURVEY OF THE DAMAGE IN EASTERN WACO.
BASED ON THEIR STUDY OF THE STORM TRACK AND THE DEBRIS PATTERNS...IT
APPEARS THAT A SHORT-LIVED TORNADO DEVELOPED.

DAMAGE WAS FIRST NOTED SOUTH OF KENDALL LANE AND APPROXIMATELY 1.25
MILES WEST OF LOOP 340. THE TORNADO A BARN...OUTBUILDINGS...AND
PUSHED OVER SEVERAL TREES ON THE SOUTH SIDE OF KENDALL LANE. A
TWO-STORY HOME PARTIALLY COLLAPSED IN THIS AREA. THE TORNADO MOVED
NORTH-NORTHEAST AND DAMAGED OUTBUILDINGS AND TREES BETWEEN KENDALL
LANE AND ORCHARD LANE. AS THE STORM CROSSED ORCHARD LANE...TWO
HOMES SUFFERED ROOF AND WINDOW DAMAGE AND SEVERAL ADDITIONAL STORAGE
BUILDINGS WERE DAMAGED. THE TORNADO DISSIPATED NORTH OF ORCHARD LANE
AND DEPOSITED DEBRIS IN THE FIELD NORTH OF ORCHARD LANE.

THE TORNADO HAD A PATH LENGTH OF APPROXIMATELY 3/4 MILE AND AN
AVERAGE PATH WIDTH OF 150 FEET. INTENSITY OF THE TORNADO IS STILL
BEING EVALUATED.

RADAR DATA SUGGEST THAT THE TORNADO DEVELOPED IN THE LOWER LEVELS OF
THE STORM. THIS TYPE OF DEVELOPMENT CAN OCCUR VERY RAPIDLY AND CAN
BE DIFFICULT TO DETECT. ADDITIONALLY...THE NIGHTTIME CONDITIONS
PROVIDED POOR VIEWING CONDITIONS FOR STORM SPOTTERS IN THE AREA.
THESE FACTORS COMBINED TO CREATE A SCENARIO WHICH WAS A DIFFICULT
CHALLENGE TO THE WARNING SYSTEM.

857 PM CDT SAT MAY 6 2006

...RESULTS OF THE SURVEY OF THE MCLENNAN COUNTY STORM OF MAY 6...

ON SATURDAY AFTERNOON...STAFF FROM THE NATIONAL WEATHER SERVICE
SURVEYED THE DAMAGE IN WACO AND MCLENNAN COUNTY. BASED ON THE
RESULTS OF THIS SURVEY...IT WAS DETERMINED THAT THE DAMAGE IN AND
NEAR WACO WAS CAUSED BY A COMBINATION OF DOWNBURST WINDS AND A
TORNADO.

ISOLATED AREAS OF WIND DAMAGE WERE NOTED IN WESTERN MCLENNAN
COUNTY...NEAR CRAWFORD...NEAR VALLEY MILLS...AND WESTERN WACO. MORE
WIDESPREAD WIND DAMAGE WAS NOTED IN WOODWAY...HEWITT...ROBINSON...
AND SOUTH WACO. THIS DAMAGE EXTENDED ALONG AND SOUTH OF THE HIGHWAY
6 CORRIDOR. MINOR ROOF DAMAGE AND DAMAGE TO TREES...SIGNS...AND
AWNINGS WAS NOTED IN THIS AREA. DAMAGE PATTERNS AND CORRELATION WITH
RADAR DATA SUGGEST DOWNBURST WINDS OF 50 TO 80 MPH WERE LIKELY
RESPONSIBLE FOR THE DAMAGE.

NORTH OF THE DOWNBURST AREA...EVIDENCE OF A CIRCULATION WAS FIRST
OBSERVED SOUTH OF NEW ROAD AND JUST WEST OF SPUR 298...OR JUST
NORTH OF RICHLAND MALL. THE TORNADO REACHED ITS PEAK INTENSITY...
AND CAUSED THE MOST SIGNIFICANT DAMAGE...JUST EAST OF SPUR 298.
SEVERAL COMMERCIAL BUILDINGS HAD CONSIDERABLE SECTIONS OF ROOF
REMOVED AND WALLS DAMAGED. NUMEROUS TREES WERE DOWNED AND POWER
POLES WERE SNAPPED IN AND EAST OF THIS AREA. THE CIRCULATION WEAKENED
AS IT APPROACHED INTERSTATE 35...AND THE LAST EVIDENCE OF CIRCULATION
WAS NOTED IN BEVERLY HILLS...APPROXIMATELY 3/4 MILE EAST OF
INTERSTATE 35. DOWNBURST-RELATED WIND DAMAGE CONTINUED TO THE EAST OF
WACO.

WHILE DEBRIS IN THE AREA NEAR AND SOUTH OF HIGHWAY 6 WAS CARRIED
MAINLY EAST AND SOUTHEAST...DEBRIS IN THE CIRCULATION AREA WAS
CARRIED TO THE NORTH AND NORTHWEST IN SOME LOCATIONS. EVIDENCE WAS
ALSO SEEN OF A CONVERGING WIND FIELD IN THIS AREA. THIS SUGGESTS
THAT A TORNADO WAS RESPONSIBLE FOR THE NORTHERN PORTION OF THE
DAMAGE SWATH.

BASED ON THE DAMAGE...THE TORNADO WILL BE GIVEN A PRELIMINARY RATING
OF A LOWER F2 ON THE FUJITA SCALE. MAXIMUM WIND SPEEDS IN THE
TORNADO WERE LIKELY IN THE 115 MPH RANGE. PATH LENGTH WAS AROUND 2.6
MILES...AND AVERAGE PATH WIDTH WAS APPROXIMATELY 150 YARDS.

THIS WAS A METEOROLOGICALLY COMPLEX EVENT. THE TYPE OF THUNDERSTORM
WHICH MOVED ACROSS THE WACO AREA IS CALLED A SUPERCELL THUNDERSTORM.
SUPERCELLS ARE CHARACTERIZED BY AN AREA OF STORM-SCALE ROTATION...
KNOWN AS A MESOCYCLONE. A STRONG DOWNDRAFT...CALLED A REAR FLANK
DOWNDRAFT...LIKELY WRAPPED AROUND THE WEST AND SOUTH SIDE OF THE
MESOCYCLONE...STRUCK THE GROUND...AND PRODUCED THE DOWNBURST DAMAGE.
JUST NORTH OF THE DOWNBURST AREA AND NEAR THE CENTER OF THE
MESOCYCLONE...A SMALL VIGOROUS AREA OF ROTATION DEVELOPED AND EVOLVED
INTO THE TORNADO.

AFTER ADDITIONAL SURVEY WORK AND CONSULTATION WITH STORM SPOTTERS
AND WIND DAMAGE EXPERTS...HERE IS UPDATED INFORMATION ON THE
COLLIN-GRAYSON COUNTY STORM OF MAY 9.

IT APPEARS THAT TWO...AND POSSIBLY THREE...TORNADOES MOVED ACROSS
NORTHERN COLLIN AND INTO SOUTHEASTERN GRAYSON COUNTIES. ON THE NIGHT
OF MAY 9...STORM SPOTTERS REPORTED A POSSIBLE TORNADO JUST NORTHWEST
OF ANNA AT APPROXIMATELY 1026 PM CDT. NO SIGNIFICANT DAMAGE WAS
REPORTED TO THE ANNA FIRE DEPARTMENT...AND NO SIGNIFICANT DAMAGE WAS
NOTED BY THE SURVEY TEAM. THEREFORE...IF A CIRCULATION WAS
PRESENT...IT WAS LIKELY BRIEF AND WOULD BE RATED F0.

AS THE STORM PASSED JUST NORTH AND NORTHEAST OF ANNA...SPOTTERS
REPORTED ANOTHER TORNADO AT 1033 PM CDT. SOME DAMAGE WAS NOTED ALONG
FARM ROAD 2862 1 TO 2 MILES NORTHEAST OF ANNA. DAMAGE WAS CONFINED
TO TREE LIMBS AND STORAGE BUILDING ROOFS...AND THIS TORNADO WILL BE
RATED F0.

THE MOST SIGNIFICANT TORNADO DEVELOPED AT APPROXIMATELY 1037 PM...3
MILES EAST-NORTHEAST OF ANNA. JUST EAST OF COLLIN COUNTY ROAD
477...THE TORNADO UNROOFED A HOME AND DAMAGED ANOTHER. TREES WERE
SNAPPED AND UPROOTED...AND POWER POLES WERE DOWNED. A ROOF WAS
DAMAGED ALONG F.M. 2862 WEST OF COLLIN COUNTY ROAD 480. THE TORNADO
THEN TURNED ON A SLIGHTLY MORE NORTHERLY TRACK.

THE TORNADO REACHED ITS MAXIMUM INTENSITY AS IT CROSSED F.M. 3133
JUST NORTH OF THE WESTMINSTER COMMUNITY. VEGETATION WEST OF F.M.
3133 WAS SCOURED. THE TORNADO HEAVILY DAMAGED TWO HOMES SOUTH OF
COLLIN COUNTY ROAD 531. A MOBILE HOME AND SEVERAL PERMANENT
STRUCTURES SUFFERED HEAVY DAMAGE ALONG BRANGUS AND BLACK
ROADS...NEAR THE COLLIN-GRAYSON COUNTY LINE. THESE WERE THE
LOCATIONS OF THE FATALITIES.

THE TORNADO REMAINED STRONG AS IT CROSSED INTO GRAYSON COUNTY.
NUMEROUS TREES WERE SNAPPED OR UPROOTED ALONG YELLOW BRIDGE
ROAD...DURHAM ROAD...AND RED MOORE ROAD. THE TORNADO DAMAGED
OUTBUILDINGS...ROLLED OVER A MOBILE HOME...AND CAUSED AT LEAST MINOR
DAMAGE TO STRUCTURES IN THIS AREA. AS THE TORNADO APPROACHED GORDON
ROAD SOUTHEAST OF THE PILOT GROVE COMMUNITY...AT LEAST TWO
ADDITIONAL HOMES WERE HEAVILY DAMAGED. THE TORNADO CROSSED F.M. 121
AND DAMAGED A SHED ALONG BETHEL CANYON ROAD...JUST WEST OF HIGHWAY
160. THE TORNADO CROSSED HIGHWAY 160 AND DISSIPATED APPROXIMATELY 3
MILES SOUTH OF WHITEWRIGHT JUST BEFORE 11 PM.

BASED ON THE DAMAGE NEAR F.M. 3133 AND AFTER CONSULTATION WITH WIND
ENGINEERS...THE THIRD TORNADO WILL BE RATED F3 ON THE FUJITA SCALE.
USING THE NEW ENHANCED FUJITA SCALE GUIDELINES...MAXIMUM WINDS WERE
LIKELY IN THE 150 TO 160 MPH RANGE. F2 DAMAGE WAS NOTED AT OTHER
LOCATIONS ALONG THE TRACK...INCLUDING THE HOMES EAST OF COLLIN
COUNTY ROAD 477...AND THE HOMES NEAR GORDON ROAD IN GRAYSON COUNTY.
THESE AREAS WILL CONTINUE TO BE EVALUATED...AND MAY BE UPGRADED TO
F3 AS WELL. PATH LENGTH OF THE THIRD TORNADO WAS 9.3 MILES...AND THE
AVERAGE PATH WIDTH WAS AROUND 300 YARDS.

WHILE THIS INFORMATION IS MORE COMPLETE...IT SHOULD STILL BE
CONSIDERED PRELIMINARY. ADDITIONAL CONSULTATION WITH STORM
SPOTTERS...A MORE DETAILED REVIEW OF RADAR DATA...AND ADDITIONAL
FOLLOWUP WITH LOCAL EMERGENCY OFFICIALS MAY RESULT IN ADJUSTMENTS TO
THIS INFORMATION.
