I don’t know what’s funnier. The guy doing this or the weather neckbeards on Twitter freaking out over it like he said the weather version of the n-word.

SURVEY SUMMARY:
A TORNADO TOUCHED DOWN IN JEFFERSON PARISH, SOUTHWEST OF
TERRYTOWN. IT MOVED NORTHEAST THROUGH JEFFERSON PARISH AND INTO
ORLEANS PARISH. AS IT MOVED NORTHEAST THROUGH THE WESTBANK, IT
CAUSED MINOR TREE DAMAGE AS WELL AS STRUCTURAL DAMAGE. THIS DAMAGE
CONSISTED OF MINOR ROOF, SIDING AND FENCE DAMAGE. THERE WAS VIDEO
FOOTAGE OF THE TORNADO CROSSING THE MISSISSIPPI RIVER AND DAMAGE
WAS FOUND ON THE EASTBANK AS IT MOVED INTO ST. BERNARD PARISH,
INTO THE TOWN OF ARABI. THE MOST INTENSE DAMAGE WAS FROM THE
RIVERBANK TO THE CANAL IN ARABI. IT WAS A VERY NARROW, INTENSE
TORNADO WITH TWO AREAS OF CONCENTRATED EF3 DAMAGE. ONE WAS A HOUSE
THAT WAS SWEPT OFF ITS RAISED FOUNDATION WITH ALL WALLS AND THE
ROOF DESTROYED. THIS WAS NEAR WHERE THE ONE FATALITY OCCURRED. DUE
TO POOR CONSTRUCTION, THIS WAS EF3. THE HIGHEST EF3 RATING WAS
GIVEN TO A HOUSE THAT WAS CONSTRUCTED IN THE LAST 6 MONTHS. WHILE
THIS HOUSE WAS RAISED ON CINDER BLOCKS, EVERY TOWER OF BLOCKS HAD
STRAPPING TO THE HOUSE. THE HOUSE HAD ADDITIONAL STRAPPING
DIRECTLY INTO THE FOUNDATION, AS WELL AS STRAPPING FROM THE CINDER
BLOCKS TO THE FOUNDATION. THE HOUSE ITSELF HELD TOGETHER BUT WAS
SHIFTED ABOUT 50 YARDS TO THE NORTH AND ROTATED ABOUT 90 DEGREES.
THE HOUSE NEXT DOOR WAS ALSO SWEPT OFF THE FOUNDATION, MOVED AND
MOSTLY DESTROYED. THIS ALSO HAD SOME EVIDENCE OF STRAPPING TO THE
SLAB FOUNDATION. THIS AREA IS WHAT WILL JUSTIFY THE 160 MPH EF3
RATING. MOST IF NOT ALL HOUSES ON THE SOUTH TO NORTH PATH WITHIN A
4 BLOCK WEST TO EAST RANGE RECEIVED MINOR TO SUBSTANTIAL ROOF
DAMAGE WITH MANY HOUSES SEEING WALLS COLLAPSED, LEAVING INTERIOR
ROOMS INTACT. THE TORNADO THEN DAMAGED ELECTRICAL TOWERS ON THE
BANK OF THE CANAL BEFORE MOVING NORTHEAST ACROSS THE CANAL. DAMAGE
WAS NOTED ON THE OTHER SIDE OF THE INTRACOASTAL WATERWAY IN NEW
ORLEANS EAST AND CONTINUED NORTHEAST. THIS DAMAGE WAS MINOR TREE
DAMAGE AND MINOR ROOF AND SIDING DAMAGE. IT IS ESTIMATED THE
TORNADO LIFTED BEFORE JOE W BROWN MEMORIAL PARK. THERE WERE ALSO
AT LEAST TWO INJURIES NOTED FROM THE SURVEY BUT ADDITIONAL
INJURIES WILL NEED TO BE REPORTED FROM THE LOCAL OFFICIALS.

SATELLITE DATA HAS STILL NOT YET BEEN RECEIVED AND DRONE VIDEO HAS
NOT BEEN FULLY ANALYZED. LENGTH, WIDTH AND TIMING INFORMATION MAY
BE UPDATED IN THE COMING DAYS. THIS DATA IS ALL PRELIMINARY UNTIL
IT IS FINALIZED IN THE OFFICIAL NWS STORM DATA RECORD.

SPECIAL THANKS TO ST. BERNARD, JEFFERSON AND NEW ORLEANS PARISH EMERGENCY
MANAGEMENT AND SAFETY OFFICIALS.
