POST-TROPICAL CYCLONE TERESA DISCUSSION NUMBER 5  
NWS NATIONAL HURRICANE CENTER MIAMI FL AL192021  
500 PM AST SAT SEP 25 2021  
 
TERESA HAS CONTINUED TO CONSIST OF JUST A SWIRL OF LOW-LEVEL CLOUDS  
SINCE LAST NIGHT. ALTHOUGH A CONVECTIVE BAND PERSISTS A COUPLE  
HUNDRED MILES NORTHEAST OF THE LOW CENTER, THE SYSTEM NO LONGER  
MEETS THE DEFINITION OF A TROPICAL CYCLONE. STRONG  
WEST-SOUTHWESTERLY WIND SHEAR SHOULD PREVENT ANY REGENERATION OF  
CONVECTION NEAR THE CENTER. ALL OF THE GLOBAL MODELS SHOW THE  
REMNANT LOW DEGENERATING INTO AN OPEN TROUGH BY SUNDAY MORNING.  
 
TERESA HAS BEEN MOVING EASTWARD OR 090/4 KT DURING THE PAST 12  
HOURS. A TURN TO THE NORTHEAST IS EXPECTED WITHIN THE NEXT COUPLE  
OF HOURS AS THE CYCLONE MOVES IN THE SOUTHWESTERLY FLOW AHEAD OF A  
DEEP-LAYER TROUGH. THE NORTHEASTWARD MOTION SHOULD CONTINUE UNTIL  
THE LOW DISSIPATES SUNDAY MORNING.
