SURVEY_SUMMARY: AFTER PASSING THROUGH HALLIBURTON...THIS TORNADO
MOSTLY MOVED ACROSS MOSTLY OPEN COUNTRY. PATH ACTUALLY CROSSED THE
PATH OF THE EARLIER POWERFUL TORNADO LESS THAN A HOUR LATER. THIS
MAKES IT DIFFICULT TO SAY WHICH STORM PRODUCED CERTAIN DAMAGE ALONG
THE PATH NEAR CODMAN...BUT BOTH WERE DOCUMENTED PHOTOGRAPHICALLY AS
BEING LARGE WEDGE TORNADOS FROM EAST OF A PAMPA TO NORTH OF MIAMI.
BEING IN VERY RURAL OPEN COUNTRY...DAMAGE WAS MAINLY CONFINED TO
TREES AND POWER POLES ALONG THE FEW ROADS IT CROSSED AND MUCH OF THE
TRACK WAS NOT ACCESSIBLE. THIS LIMITED THE EF RATING FOR THIS STORM.
IT IS UNCLEAR WHICH TORNADO DERAILED A TRAIN NEAR CODMAN.

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
EF3...STRONG....136 TO 165 MPH
