SUMMARY: A SIGNIFICANT DOWNBURST WIND EVENT OCCURRED WEST AND  
SOUTHWEST OF DALHART, TX ON SUNDAY EVENING. THE DOWNBURST WAS  
ASSOCIATED WITH THE REAR FLANK DOWNDRAFT OF A SUPERCELL  
THUNDERSTORM. DAMAGE FROM THE DOWNBURST WAS INITIALLY OBSERVED  
AT THE TWISTED ELMS GOLF COURSE WHERE SEVERAL TREES WERE  
UPROOTED AND MANY LARGE BRANCHES WERE DOWNED, INCLUDING SOME  
ONTO POWER LINES. DAMAGE AT THE GOLF COURSE WAS ESTIMATED TO  
BE CAUSED BY WINDS AROUND 75 TO 85 MPH. THE DAMAGE CONTINUED

SEVERE STRAIGHT LINE WIND DAMAGE PEAKED AT THE AIRPORT WHERE A  
74 MPH WIND WAS OBSERVED BY NWS ASOS EQUIPMENT BEFORE THE

MULTIPLE AIRPORT HANGARS THAT WERE COMPLETELY DESTROYED. DEBRIS  
FROM THE HANGARS WAS FOUND UP TO A HALF MILE AWAY. SEVERAL  
SMALL PLANES AND A POP-UP CAMPER WERE FLIPPED AND THROWN UP TO  
50 YARDS. DAMAGE AT THE AIRPORT WAS ESTIMATED TO BE FROM 100 TO
