REF/A/RMG/NAVPACMETOCCEN PEARL HARBOR HI/041921Z APR 01//
AMPN/REF IS TROPICAL CYCLONE FORMATION ALERT (WTPS21 PGTW 041930)//
RMKS/
1. IMMEDIATE DELIVERY REQ TO AMEMBASSY PORT MORESBY
2. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
155 NM EITHER SIDE OF A LINE FROM 18.6S5 164.3E4 TO 12.9S2
168.0E5 WITHIN THE NEXT 12 TO 24 HOURS. AVAILABLE DATA DOES NOT
JUSTIFY ISSUANCE OF NUMBERED TROPICAL CYCLONE WARNINGS AT THIS
TIME. WINDS IN THE AREA ARE ESTIMATED TO BE 25 TO 30 KNOTS. METSAT
IMAGERY AT 041630Z4 INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 13.9S3 167.3E7. THE SYSTEM IS MOVING SOUTHWESTWARD AT 13 KNOTS.
3. REMARKS:
THE AREA OF CONVECTION LOCATED OVER NORTHERN VANAUATU, HAS CONTINUED
TO ORGANIZE OVER THE PAST 12 HOURS. RECENT MICROWAVE IMAGERY
INDICATES THE BANDS OF STRONG CONVECTION ASSOCIATED WITH THE SYSTEM.
RECENT SYNOPTIC AND SCATTEROMETER DATA INDICATE A LOW LEVEL
CIRCULATION CENTER ASSOCIATED WITH THE CONVECTION. UW-CIMSS VERTICAL
WIND SHEAR PRODUCT INDICATES THE SYSTEM IS UNDER WEAK TO MODERATE
VERTICAL WIND SHEAR AND BENEATH AN UPPER-LEVEL ANTI-CYCLONE. MINIMUM
SEA LEVEL PRESSURES IS ESTIMATED AT 1001 MB THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS UPGRADED TO GOOD.
4. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
051930Z8.

REMARKS:
052100Z8 POSITION NEAR 14.0S5 165.3E5.
TROPICAL CYCLONE 19P (SOSE) HAS DEVELOPED OVER THE SOUTHERN
CORAL SEA JUST NORTH OF VANUATU. TC 19P HAS TRACKED WESTWARD AT
08 KNOTS DURING THE PAST 6 HOURS. THE WARNING POSTION IS BASED ON
051730Z6 INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED
ON CURRENT INTENSITY ESTIMATES OF 30 TO 45 KNOTS. INFRARED ANIMATION
DEPICTS A SIGNIFICANT INCREASE IN DEEP CONVECTION COVERAGE DURING
THE PAST 6 HOURS. WATER VAPOR LOOP REVEALS IMPRESSIVE OUTFLOW
OVER THE SYSTEM. TC 19P SHOULD DRIFT WESTWARD OVER THE NEXT 24
HOURS BEFORE SHOWING A MORE SOUTHWESTWARD TRACK. SYSTEM IS
FORECAST TO INTENSIFY AT A CLIMATOLOGICAL RATE THROUGH THE
PERIOD. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 051800Z4 IS 12 FEET.

REMARKS:
060900Z5 POSITION NEAR 13.7S1 165.1E3.
TROPICAL CYCLONE 19P (SOSE), LOCATED ABOUT 95 NM NORTHWEST OF
VANUATU,HAS TRACKED WEST-SOUTHWESTWARD AT 2 KNOTS OVER THE PAST 6
HOURS. THE WARNING POSITION IS BASED ON 060530Z4 VISIBLE AND
INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON
CURRENT INTENSITY ESTIMATES OF 35 KNOTS AND SYNOPTIC OBSERVATIONS OF
25 AND 48 KNOTS. ANIMATED SATELLITE IMAGERY INDICATES A BROAD
CIRCULATION WITH BETTER ORGANIZATION AND INCREASED CONVECTION
COVERAGE DURING THE PAST 6 HOURS. WATER VAPOR IMAGERY REVEALS
IMPRESSIVE OUTFLOW. THE SYSTEM IS FORECAST TO TRACK SLOWLY WEST-
SOUTHWESTWARD FOR THE NEXT 12 HOURS AND THEN TRACK INCREASINGLY
SOUTHWARD WITH AN APPROACHING TROUGH. TC 19P IS FORECAST TO
INTENSIFY AT A CLIMATOLOGICAL RATE THROUGH THE FORECAST PERIOD.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 060600Z2 IS 14 FEET. NEXT

082100Z1 POSITION NEAR 21.0S3 169.7E3.
TROPICAL CYCLONE (TC) 19P (SOSE), LOCATED APPROXIMATELY 170 NM
NORTHEAST OF NEW CALEDONIA, HAS TRACKED SOUTHEASTWARD AT 9 KNOTS
OVER THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON 081730Z9
INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON
CURRENT INTENSITY ESTIMATES OF 45 AND 65 KNOTS. ANIMATED SATELLITE
IMAGERY SHOWS INDICATIONS OF INCREASING UPPER LEVEL WESTERLIES
AFFECTING TC 19P. A 081320Z4 TROPICAL RAINFALL MEASURING MISSION
(TRMM) PASS REVEALED A 24 NM EYE WITH DEEP CONVECTION IN SOUTHERN
SEMI-CIRCLE OF THE EYEWALL AND A WEAK BANDING FEATURE TO THE EAST.
THE SYSTEM IS FORECAST TO TRACK SOUTH-SOUTHEASTWARD BEFORE TURNING
SOUTH-SOUTHWEST AS A DYNAMIC RIDGE TO THE SOUTH STEERS THE SYSTEM.
TC 19P IS EXPECTED TO MAINTAIN INTENSITY THROUGH THE FORECAST PERIOD.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 081800Z7 IS 20 FEET. NEXT WARNINGS
AT 090900Z8 AND 092100Z2.//
