REMARKS:
120300Z6 POSITION NEAR 19.9S9 86.9E3.
TROPICAL CYCLONE (TC) 17S (NICKY-HELMA), LOCATED APPROXIMATELY
680 NM SOUTHWEST OF THE COCOS ISLANDS, HAS TRACKED SOUTH-
SOUTHWESTWARD AT 06 KNOTS OVER THE PAST SIX HOURS. THE WARNING
POSITION IS BASED ON 112330Z0 ENHANCED INFRARED SATELLITE
IMAGERY. THE WARNING INTENSITY IS BASED ON SATELLITE CURRENT
INTENSITY ESTIMATES OF 65, 77 AND 90 KNOTS. ANIMATED ENHANCED
INFRARED SATELLITE IMAGERY SHOWS POLEWARD OUTFLOW BEGINNING TO
INTERACT WITH THE BAROCLINIC ZONE. TC 17S IS FORECAST TO TRACK
POLEWARD ALONG THE WESTERN PERIPHERY OF A MID LEVEL STEERING
RIDGE TO THE EAST. TC 17S IS EXPECTED TO WEAKEN GRADUALLY
THROUGH THE FORECAST PERIOD AS THE SYSTEM ENCOUNTERS INCREASED
VERTICAL WIND SHEAR AND BEGINS TRANSITION INTO AN EXTRATROPICAL
SYSTEM. THE AVAILABLE DYNAMIC AIDS CONSISTING OF NOGAPS, WBAR,
EGRR, GFDN, AND NCEP GFS ARE IN GOOD AGREEMENT WITH THIS
SCENARIO. THIS FORECAST IS BASED ON A CONSENSUS OF ALL AVAILABLE
AIDS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 120000Z3 IS 18 FEET.
NEXT WARNINGS AT 121500Z9 AND 130300Z7.//
