REMARKS:
260300Z1 POSITION NEAR 17.1S9 92.3E4.
TROPICAL CYCLONE (TC) 20S (OSCAR), LOCATED APPROXIMATELY 375 NM
SOUTHWEST OF THE COCOS ISLANDS, HAS TRACKED SOUTH-SOUTHWESTWARD
AT 03 KNOTS OVER THE PAST 06 HOURS. THE WARNING POSITION IS BASED
ON 252330Z5 INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS
BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 102 AND 115 KNOTS.
ANIMATED IMAGERY AND RECENT MICROWAVE INDICATE THAT TC 20S HAS
INTENSIFIED SIGNIFICANTLY OVER THE LAST 12 HOURS. THE SYSTEM IS
FORECAST TO TRACK SLIGHTLY POLEWARD THROUGH THE NEXT 12 HOURS AS
A MIGRATORY SHORTWAVE WEAKENS THE MID LEVEL STEERING RIDGE SOUTH
OF THE SYSTEM. BEYOND TAU 12 THE MID LEVEL RIDGE IS FORECAST TO
BUILD BACK IN AND TRACK TC 20S SOUTHWESTWARD ALONG THE NORTHERN
PERIPHERY OF THE MID-LEVEL STEERING RIDGE. TC 20S IS EXPECTED TO
INTENSIFY AT A SLIGHTLY LESS THAN CLIMATOLOGICAL RATE THROUGH THE
FORECAST PERIOD IN A FAVORABLE UPPER LEVEL ENVIRONMENT OF GOOD
OUTFLOW AND WEAK VERTICAL WIND SHEAR. THE AVAILABLE DYNAMIC AIDS,
CONSISTING OF NOGAPS, TLAPS, TCLAPS, NCEP GFS, GFDN AND EGRR ARE
IN REASONABLE AGREEMENT WITH THIS SCENARIO. THIS FORECAST IS
BASED ON A BLEND OF THE AVAILABLE AIDS. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 260000Z8 IS 24 FEET. NEXT WARNINGS AT 261500Z4 AND
270300Z2. REFER TO TROPICAL CYCLONE 18S (FAY) WARNINGS (WTXS31 PGTW)
FOR TWELVE-HOURLY UPDATES.//
