REMARKS:
090900Z8 POSITION NEAR 21.1S4 169.0W6.
TROPICAL CYCLONE (TC) 15P (DOVI), LOCATED APPROXIMATELY 450 NM
SOUTH-SOUTHEAST OF PAGO PAGO, HAS TRACKED SOUTH-SOUTHWEST AT 07
KNOTS OVER THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON
090530Z7 ENHANCED INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY
IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 127 KNOTS AND
SLIGHT WEAKENING IN THE PAST 12 HOURS. ANIMATED WATER VAPOR
SATELLITE IMAGERY DEPICTS GOOD POLEWARD OUTFLOW. TC 15P IS FORECAST
TO TRACK GENERALLY POLEWARD DURING THE FORECAST PERIOD ALONG THE
WESTERN PERIPHERY OF A POLEWARD ORIENTED RIDGE TO THE EAST. TC 15P
IS FORECAST TO SLOWLY WEAKEN IN THE NEXT 24 HOURS BEFORE WEAKENING
MORE RAPIDLY AS IT TRACKS OVER COOLER SST AND INTO UNFAVORABLE
VERTICAL WIND SHEAR. THE AVAILABLE DYNAMIC AIDS, INCLUDING NGPS,
GFDN, UKMET (EGRR), AND NCEP AVIATION (AVN) ARE IN GOOD AGREEMENT
WITH THIS SCENARIO. OUR FORECAST IS BASED ON PERSISTENCE AND A BLEND
OF AVAILABLE DYNAMIC AIDS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
090600Z5 IS 34 FEET. NEXT WARNINGS AT 092100Z2 AND 100900Z0.//
