REMARKS:
261500Z4 POSITION NEAR 17.6S4  91.9E9.
TROPICAL CYCLONE (TC) 20S (OSCAR), LOCATED APPROXIMATELY
410 NM SOUTHWEST OF THE COCOS ISLANDS, HAS TRACKED SOUTH-
SOUTHWESTWARD AT 04 KNOTS OVER THE PAST 06 HOURS. THE
WARNING POSITION IS BASED ON 261130Z3 ENHANCED INFRARED
SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON
SATELLITE CURRENT INTENSITY ESTIMATES OF 102 AND 115 KNOTS.
THE SYSTEM IS FORECAST TO TRACK SLIGHTLY SOUTHWESTWARD
THROUGH THE FORECAST PERIOD INTO A WEAKNESS IN THE MID
LEVEL STEERING RIDGE SOUTH OF THE SYSTEM RESULTING FROM A
EASTWARD PROPAGATING SHORTWAVE. RECENT ANIMATED SATELLITE
IMAGERY INDICATES A BREAKDOWN OF THE PREVIOUSLY WELL DEFINED
EYE AND WEAKENING IN TC 20S AS IT CROSSES THE AXIS OF THE
PASSING SHORTWAVE TROUGH. TC 20S IS EXPECTED TO INTENSIFY AT
A SLIGHTLY LESS THAN CLIMATOLOGICAL RATE THROUGH THE FORECAST
PERIOD IN A FAVORABLE UPPER LEVEL ENVIRONMENT OF MODERATE OUTFLOW
AND WEAK VERTICAL WIND SHEAR. THE AVAILABLE DYNAMIC AIDS,
CONSISTING OF NOGAPS, TLAPS, TCLAPS, NCEP GFS AND GFDN ARE IN
GOOD AGREEMENT WITH THIS SCENARIO WITH EGRR AN OUTLIER TO THE WEST.
THIS FORECAST IS BASED ON A BLEND OF THE AVAILABLE AIDS. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 261200Z1 IS 24 FEET. NEXT WARNINGS AT
270300Z2 AND 271500Z5. REFER TO TROPICAL CYCLONE 18S (FAY) WARNINGS
(WTXS31 PGTW) FOR TWELVE-HOURLY UPDATES.//
