REMARKS:
131500Z0 POSITION 31.3S7   67.7E0
TROPICAL CYCLONE 20S (ANACELLE) IS MOVING SOUTHEASTWARD AT 24
KNOTS. THERE IS NO SIGNIFICANT CHANGE IN THE FORECAST
PHILOSOPHY. THE SYSTEM IS EXPECTED TO CONTINUE IN ITS CURRENT
DIRECTION AS IT MOVES POLEWARD OF THE SUB-TROPICAL RIDGE AXIS.
TC 20S (ANACELLE) HAS MOVED OVER COLDER SURFACE WATERS AND
ANIMATED INFRARED IMAGERY INDICATES THAT IT IS ALSO
EXPERIENCING COLD AIR ADVECTION. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 131200Z IS 25 FEET. NEXT WARNINGS AT 140300Z8
(DTG 140151Z2) AND 141500Z1 (DTG 141351Z5). REFER TO TROPICAL
