...NWS DAMAGE SURVEY FOR NOVEMBER 06TH, 2018 TORNADO EVENT...

A LINE OF STORMS MOVED THROUGH CENTRAL ALABAMA DURING THE EARLY- 
MORNING HOURS OF TUESDAY, NOVEMBER 06TH. STRONG WIND SHEAR WAS 
ALREADY IN PLACE, WITH A NORTHWARD-MOVING INSTABILITY AXIS THAT AIDED
IN A WINDOW FOR STORM INTENSIFICATION AND MORE ROBUST ROTATION. ONE 
OF THESE STORMS MOVED INTO SOUTHERN LAMAR COUNTY FROM MISSISSIPPI. 
AFTER SOME INTERACTION BETWEEN THE STORM'S COUPLET AND A 
SOUTHEASTWARD-MOVING WIND SHIFT, PART OF THE LARGER CONVECTIVE LINE,
THE COUPLET INTENSIFIED AS IT MOVED INTO THE MILLPORT AREA. THIS 
FEATURE ENDED UP PRODUCING A TORNADO ON THE EASTERN SIDE OF TOWN.

SURVEY SUMMARY:
NWS METEOROLOGISTS SURVEYED MINOR DAMAGE IN FAR SOUTHERN LAMAR COUNTY
AND DETERMINED THAT IT WAS CONSISTENT WITH A LOW-END, EF-1 TORNADO.
THE TORNADO TOUCHED DOWN IN A WOODED AREA ABOUT 150 YARDS WEST OF
LEONARD DRIVE, OVER A GRASSY PLOT, AND THEN UPROOTED AND SNAPPED A
DOZEN PINE TREES ACROSS A UTILITY RIGHT OF WAY. THE WORST DAMAGE,
WHICH TIPPED THE RATING INTO THE LOW-END, EF-1 RANGE, OCCURRED WHERE
THE TORNADO FIRST BEGAN. THE TORNADO THEN CONTINUED EAST-
SOUTHEASTWARD ACROSS LEONARD DRIVE, PRODUCING MINOR SPORADIC TREE 
DAMAGE FOR THE REMAINDER OF THE PATH, WHICH CROSSED EVANS ROAD/SLS 
ROAD, JUST SOUTH OF SOUTH LAMAR HIGH SCHOOL. SPORADIC TREE DAMAGE 
CONTINUED TO JUST ACROSS CONKLAN ROAD, WHERE SEVERAL LARGE LIMBS AND 
TREE TOPS WERE TWISTED BUT STILL INTACT.

EF SCALE: THE ENHANCED FUJITA SCALE CLASSIFIES TORNADOES INTO THE 
FOLLOWING CATEGORIES:

EF0...WEAK......65 TO 85 MPH
EF1...WEAK......86 TO 110 MPH
EF2...STRONG....111 TO 135 MPH
