REMARKS:
021500Z8 POSITION NEAR 8.0S8 173.8W9.
TROPICAL CYCLONE (TC) 07P (HETA), LOCATED APPROXIMATELY
350 NM NORTH-NORTHWEST OF APIA, WESTERN SAMOA, HAS
TRACKED EASTWARD AT 03 KNOTS OVER THE PAST SIX HOURS. THE
WARNING POSITION IS BASED ON 021130Z7 ENHANCED INFARED SATELLITE
IMAGERY. THE WARNING INTENSITY IS BASED ON SATELLITE CURRENT
INTENSITY ESTIMATES OF 45 AND 55 KNOTS. RECENT MICROWAVE IMAGERY
REVEALS THE DEEP CONVECTION IS NORTH OF THE LOW LEVEL CIRCULATION
CENTER (LLCC). TC 07P IS EXPECTED TO TRACK EAST-SOUTHEASTWARD AND
THEN CONTINUE RECURVING TO A MORE POLEWARD TRACK. THE SYSTEM IS
FORECAST TO INTENSIFY SLOWLY IN A MODERATELY FAVORABLE ENVIRONMENT
THROUGH THE FORECAST PERIOD. THE AVAILABLE DYNAMIC AIDS, CONSISTING
OF NOGAPS, NCEP GFS, UKMET (EGRR) AND THE BETA ADVECTION MODELS
ARE SEPARATED INTO TWO DISTINCT CLUSTERS. THE DYNAMIC AIDS DEPICT
A SHARP RECURVE SCENARIO WITH THE TC RECURVING BACK UPON ITSELF
AND CROSSING OVER THE HISTORICAL TRACK. THE BETA ADVECTION MODELS
CONTINUE TO DEPICT A MORE GRADUAL RECURVE SITUATION. THE FORECAST
IS BASED ON A BLEND OF NOGAPS, UKMET (EGRR), AND THE BETA ADVECTION
MODELS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 021200Z IS 22 FEET.
NEXT WARNINGS AT 022100Z5, 030300Z6, 030900Z2 AND 031500Z9.//
