REMARKS:
052100Z8 POSITION NEAR 17.2S0 162.4W3.
TROPICAL CYCLONE (TC) 15P (MEENA), LOCATED APPROXIMATELY 325 NM
NORTH-NORTHWEST OF RAROTONGA, HAS TRACKED SOUTH-SOUTHEASTWARD AT 10
KNOTS OVER THE PAST 06 HOURS. THE WARNING POSITION IS BASED ON
051730Z6 ENHANCED INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY
IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 115 AND 127
KNOTS. RECENT ANIMATED ENHANCED WATER VAPOR SATELLITE IMAGERY REVEALS
SIGNIFICANT EQUATORWARD OUTFLOW, AND MICROWAVE IMAGERY SHOWS A WELL
DEFINED EYE. TC 15P IS FORECAST TO CONTINUE TRACKING POLEWARD AROUND
THE WESTERN PERIPHERY OF THE SUBTROPICAL STEERING RIDGE ANCHORED OVER
TAHITI. DUE TO VERY FAVORABLE OUTFLOW AND THE FORMATION OF AN EYE,
THE INTENSITY OF TC 15P IS EXPECTED TO STRENGTHEN AT A CLIMATOLOGICAL
RATE THROUGH THE ENTIRE FORECAST PERIOD. AFTER TAU 48, THE SYSTEM
SHOULD MERGE WITH THE MIDLATITUDE WESTERLIES AND BEGIN EXTRATROPICAL
TRANSITION. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 051800Z4 IS 38 FEET.
NEXT WARNINGS AT 060900Z5 AND 062100Z9.//
Now up to 115 kts wow what a rapid intensification trend this cyclone has had.
