THE LAST CLUSTER OF CONVECTION NEAR THE CENTER DISSIPATED A FEW HOURS AGO...AND LAST-LIGHT VISIBLE IMAGES THE CONVECTION-FREE CIRCULATION MOVING INTO A STRATOCUMULUS FIELD. DVORAK INTENSITY ESTIMATES CONTINUE TO DECREASE...SO THE INITIAL INTENSITY IS ESTIMATED TO BE 30 KT...WHICH COULD BE GENEROUS. ALTHOUGH MOVING OVER MARGINALLY WARM WATERS...NARDA IS EXPECTED TO ENCOUNTER INCREASING WESTERLY VERTICAL SHEAR WHILE IT SIMULTANEOUSLY MOVES INTO AN EVEN DRIER AND MORE STABLE AIR MASS. IF NO SIGNIFICANT DEEP CONVECTION RETURNS SOON...NARDA IS LIKELY TO BE DECLARED A REMNANT LOW IN 12 HOURS OR LESS. THE INITIAL MOTION IS NEARLY THE SAME AS BEFORE...295/10. NOW THAT THE CIRCULATION OF NARDA HAS BECOME SHALLOW...THE CYCLONE IS FORECAST TO SLOW DOWN AND TURN WESTWARD AND THEN WEST-SOUTHWESTARD IN THE LOW-LEVEL TRADES UNTIL DISSIPATION. THE TRACK FORECAST IS ADJUSTED SLIGHTLY FARTHER SOUTH IN THE DIRECTION OF THE MULTI-MODEL CONSENSUS...BUT NOT AS FAR SOUTH AS THE LATEST GFS/ECMWF SOLUTIONS.
