REMARKS:
070900Z POSITION NEAR 17.4S 173.4E.
07APR20. TROPICAL CYCLONE (TC) 25P (HAROLD), LOCATED APPROXIMATELY 
337 NM WEST OF SUVA, FIJI, HAS TRACKED EAST-SOUTHEASTWARD AT 15 
KNOTS (KTS) OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED 
SATELLITE IMAGERY REVEALS AN EMBEDDED CENTER WITH THE BULK OF DEEP 
CONVECTION POLEWARD OF THE INITIAL POSITION. A 070541Z SSMIS 91 GHZ 
MICROWAVE IMAGE SHOWS A PARTIAL EYEWALL STILL EXISTS ON THE NORTHERN 
SIDE OF THE LOW LEVEL CIRCULATION BUT A MICROWAVE EYE IS NOT 
EVIDENT. COMBINED, THE TWO SOURCES PROVIDE GOOD CONFIDENCE IN THE 
INITIAL POSITION. THE 110 KT INITIAL INTENSITY IS SLIGHTLY BELOW 
PGTW AND PHFO DVORAK CURRENT INTENSITY ESTIMATES THAT CONSTRAINTS 
ARE MAINTAINING AT T6.0-6.5 (115-127 KTS). WITH LOW (10-15 KT) 
VERTICAL WIND SHEAR (VWS), EXCELLENT POLEWARD OUTFLOW, AND WARM (28-
29 CELSIUS) SEA SURFACE TEMPERATURE (SST), THE ENVIRONMENT IS 
SUPPORTIVE, ALTHOUGH LESS THAN PREVIOUS WARNINGS DUE TO A SLIGHTLY 
WEAKER EQUATORWARD OUTFLOW CHANNEL. FOR THE DURATION OF THE 
FORECAST, TC 25P WILL TRACK ALONG THE SOUTHERN PERIPHERY OF AN 
EXTENSIVE NORTHWEST-TO-SOUTHEAST ORIENTED SUBTROPICAL RIDGE (STR). 
AS IT TRACKS SOUTHEASTWARD, THE ALONG TRACK SPEED WILL ACCELERATE AS 
THE SYSTEM BEGINS INTERACTING WITH THE MIDLATITUDE WESTERLIES AND 
BEGINS EXTRATROPICAL TRANSITION (BY TAU 36). AROUND TAU 48, THE 
SYSTEM WILL MOVE UNDER THE SUBTROPICAL JET AND THE ASSOCIATED HIGH 
VWS SHOULD CAUSE SIGNIFICANT WEAKENING. EXTRATROPICAL TRANSITION 
SHOULD COMPLETE BY TAU 72. NUMERICAL MODEL GUIDANCE IS IN GOOD 
AGREEMENT ON THE TRACK DIRECTION BUT TRACK SPEED VARIES 
SIGNIFICANTLY AMONG THE MEMBERS AFTER TAU 36. BASED PRIMARILY ON 
UNCERTAINTY IN ALONG TRACK SPEED, THERE IS FAIR CONFIDENCE IN THE 
JTWC TRACK FORECAST. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 070600Z IS 
42 FEET. NEXT WARNINGS AT 071500Z, 072100Z, 080300Z AND 080900Z.//
