REMARKS:
040900Z3 POSITION NEAR 14.1S6 166.7W0.
TROPICAL CYCLONE (TC) 15P (MEENA), LOCATED APPROXIMATELY 275 NM
EAST OF PAGO PAGO, AMERICAN SAMOA, HAS TRACKED EAST-SOUTHEAST
AT 06 KNOTS OVER THE PAST 06 HOURS. THE WARNING POSITION IS BASED
ON 040530Z2 ENHANCED INFRARED SATELLITE IMAGERY. THE WARNING
INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF
55 AND 65 KNOTS. RECENT ANIMATED SATELLITE IMAGERY SHOWS THAT DEEP
CONVECTION CONTINUES TO CYCLE OVER A WELL DEFINED LOW LEVEL
CIRCULATION CENTER. ANIMATED WATER VAPOR IMAGERY SHOWS GOOD
VENTILATION IN THE EQUATORWARD DIRECTION. TC 15P IS FORECAST TO
BEGIN TRACKING POLEWARD AS A MID LEVEL STEERING RIDGE BEGINS TO
BUILD IN FROM THE EAST. ALL AVAILABLE MODELS SHOW THAT THE VERTICAL
SHEAR WILL REMAIN WEAK AND THE OUTFLOW FAVORABLE, SO THE CYCLONE IS
FORECAST TO CONTINUE TO INTENSIFY. THE AVAILABLE NUMERICAL MODELS
OF NCEP GFS, NOGAPS, WBAR, AND UKMET ARE IN GOOD AGREEMENT WITH
THIS SCENARIO. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 150600Z2 IS 26
FEET. NEXT WARNINGS AT 042100Z7 AND 050900Z4.//
