REMARKS:
130900Z3 POSITION NEAR 14.9S4 71.3E1.
TROPICAL CYCLONE (TC) 17S (HAPE), LOCATED APPROXIMATELY 475 NM
SOUTH OF DIEGO GARCIA, HAS TRACKED NORTHEASTWARD AT 07 KNOTS OVER
THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON 122330Z1 VISIBLE
AND INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON
SATELLITE CURRENT INTENSITY ESTIMATES OF 77 KNOTS. RECENT MICROWAVE
IMAGERY REVEALED A WEAK BANDING EYE FEATURE ASSOCIATED WITH A SMALL
SYSTEM. TC 17S IS CURRENTLY TRACKING EQUATORWARD TOWARDS A WEAKNESS
IN THE LOW TO MID-LEVEL RIDGE NORTH OF THE SYSTEM. IN 12 TO 24
HOURS, THE SUB-TROPICAL RIDGE IS EXPECTED TO BUILD EAST-NORTHEAST OF
THE SYSTEM RESULTING IN A POLEWARD TRACK. TC 17S IS FORECAST TO
SLOWLY INTENSIFY THROUGH THE PERIOD AS OUTFLOW REMAINS MARGINAL. THE
AVAILABLE DYNAMIC AIDS CONSISTING OF TLAPS, AFWA MM5, NOGAPS, GFDN,
UKMET (EGRR) AND THE NCEP AVIATION (AVN) MODELS ARE IN GOOD
AGREEMENT WITH THIS SCENARIO. OUR FORECAST IS BASED ON A BLEND OF
PERSISTENCE AND ALL AVAILABLE DYNAMIC AIDS. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 130600Z0 IS 20 FEET. NEXT WARNINGS AT 132100Z7 AND
140900Z4. REFER TO TROPICAL CYCLONE 14S (FIONA) WARNINGS (WTXS31
PGTW) FOR THE FINAL WARNING. REFER TO TROPICAL CYCLONE 16S (GERRY)
WARNINGS (WTXS32 PGTW) FOR TWELVE-HOURLY UPDATES. REFER TO TROPICAL
