REMARKS:
270900Z8 POSITION NEAR 22.1S5 169.5E1.
TROPICAL CYCLONE (TC) 13P (IVY), LOCATED APPROXIMATELY 220
NM SOUTH-SOUTHEAST OF PORT VILA, VANUATU, HAS TRACKED
SOUTHWARD AT 12 KNOTS OVER THE PAST SIX HOURS. THE WARNING
POSITION IS BASED ON 270530Z7 ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON
SATELLITE CURRENT INTENSITY ESTIMATES OF 102 KNOTS. COOLER
SEA SURFACE TEMPERATURES, DIMINISHED UPPER LEVEL OUTFLOW AND
INCREASED VERTICAL WIND SHEAR ARE EXPECTED TO WEAKEN THE
SYSTEM AS IT TRANSITIONS TO AN EXTRATROPICAL SYSTEM. TC 13P
IS EXPECTED TO CONTINUE TRACKING POLEWARD AND COMPLETE
EXTRATROPICAL TRANSITION BY TAU 48. AVAILABLE DYNAMIC AIDS,
CONSISTING OF UKMET (EGRR), NOGAPS, AND NCEP GFS ARE IN GOOD
AGREEMENT. THIS FORECAST IS BASED ON A CONSENSUS OF ALL
AVAILABLE AIDS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 270600Z5 IS
30 FEET. NEXT WARNINGS AT 272100Z2 AND 280900Z9.//
