REMARKS:
121500Z9 POSITION 26.1S9   62.0E8
TROPICAL CYCLONE 20S (ANACELLE) IS MOVING SOUTHEASTWARD AT 15
KNOTS. THE SYSTEM HAS BEGUN TO ACCELERATE AND IS EXPECTED TO
CONTINUE TO DO THIS AS IT MOVES POLEWARD OF THE SUBTROPICAL
RIDGE AXIS. GRADUAL WEAKENING IS ALSO EXPECTED AS COLDER SEA
SURFACE TEMPERATURES ARE ENCOUNTERED. EXTRATROPICAL TRANSITION
IS ANTICIPATED TO BEGIN NEAR THE 24 HOUR POSITION. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 121200Z IS 23 FEET. NEXT WARNINGS AT
130300Z7 (DTG 130151Z1) AND 131500Z0 (DTG 131351Z4). REFER TO
TROPICAL CYCLONE 22S (VICTOR) WARNINGS (WTXS33 PGTW) FOR SIX-
HOURLY UPDATES.//
