SUBJ/TROPICAL CYCLONE FORMATION ALERT
091323Z FEB 99//
RMKS/
1. IMMEDIATE DELIVERY REQ TO AMEMBASSY SUVA
2. IMMEDIATE DELIVERY REQ TO AMEMBASSY PORT MORESBY AND AMEMBASSY
HONIARA SOLOMON ISLANDS
3. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
A 200 NM RADIUS OF 13.2S6 160.4E1 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 20 TO 25 KNOTS. METSAT IMAGERY AT 091130Z INDICATES THAT A
CIRCULATION CENTER IS LOCATED NEAR 13.2S6 160.4E1. THE SYSTEM IS
QUASI-STATIONARY.
4. REMARKS: 091130 INFRARED SATELLITE IMAGERY INDICATES A WELL
DEFINED LOW LEVEL CIRCULATION CENTER ASSOCIATED WITH THE CONVECTION.
CURRENT SATELLITE INTENSITY ESTIMATES AND SYNOPTIC SHIP REPORTS IN
THE AREA INDICATE MAXIMUM WINDS AT 25 KNOTS. MODERATE SHEAR IS
ADVECTING MUCH OF THE CIRRUS TO THE NORTHEAST. HOWEVER, AN
UPPER-LEVEL ANTICYCLONE VISIBLE IN THE WATER VAPOR IMAGERY NORTH OF
THE SYSTEM MAY ALLOW FOR INCREASED OUTFLOW AND STIMULATE FURTHER
DEVELOPMENT. THE UW-CIMSS SHEAR PRODUCT INDICATES STRONG SHEAR TO
THE NORTH, BUT MODERATE TO WEAK IN THE IMMEDIATE VICINITY OF THE
SYSTEM. SEA SURFACE TEMPERATURE IS NEAR 29 DEGREES, AND MINIMUM SEA
LEVEL PRESSURE IS NEAR 999 MB. THE POTENTIAL FOR THE DEVELOPMENT OF
A SIGNIFICANT TROPICAL CYCLONE WITHIN 24 HOURS IS GOOD.
5. THIS ALERT VALID UNTIL 101330Z8.//

TROPICAL CYCLONE 19P HAS FORMED IN THE MONSOON TROUGH SOUTH OF THE
SOLOMON ISLANDS AND IS DRIFTING SLOWLY NORTHEASTWARD IN WEAK
ENVIRONMENTAL STEERING FLOW. ANIMATED VISIBLE AND INFRARED
SATELLITE IMAGERY INDICATE DEEP CONVECTION HAS ORGANIZED INTO
SPIRAL BANDS NORTH AND WEST OF THE SYSTEM CENTER. UPPER-LEVEL
OUTFLOW IS FAIR TO GOOD IN ALL QUADRANTS. THE WARNING POSITION AND

ESTIMATES OF 25 KNOTS AND EXTRAPOLATION FROM SHIP SYNOPTIC DATA.
TROPICAL CYCLONE 19P IS FORECAST TO TURN TOWARD THE SOUTHEAST AND
ACCELERATE TOWARD THE END OF THE FORECAST PERIOD DUE TO A BUILDING
MID-LEVEL RIDGE TO ITS EAST. TC 19P IS EXPECTED TO SLOWLY INTENSIFY
AS ITS UPPER-LEVEL ANTICYCLONE STRENGTHENS. MAXIMUM SIGNIFICANT

TROPICAL CYCLONE 19P HAS REMAINED QUASISTAIONARY SOUTH OF THE
SOLOMON ISLANDS OVER THE PAST 12 HOURS. THE WARNING POSITION IS
BASED UPON 101130Z6 ANIMATED INFRARED SATELLITE IMAGERY WITH A
CURRENT INTENSITY ESTIMATE OF 30 KNOTS. SHIP AND SYNOPTIC DATA ARE
INDICATING 20 KNOT WINDS UP TO 180 NM FROM THE CENTER. ANIMATED
INFRARED SATELLITE IMAGERY INDICATES STRONG UPPER-LEVEL OUTFLOW TO
THE NORTH OF TC 19P AS WELL AS AN AREA OF STRONG SUBSIDENCE SOUTH
OF THE SYSTEM. SOUTHERLY FLOW FROM THIS AREA IS ENTRAINING DRY AIR
INTO THE LOWER AND MID LEVELS OF TC 19P, HINDERING ITS DEVELOPMENT.
TROPICAL CYCLONE 19P IS FORECAST TO MOVE SLOWLY UNTIL PICKED UP BY
THE STEERING INFLUENCE OF THE SUBTROPICAL RIDGE WHICH WILL BEGIN TO
MOVE THE SYSTEM EASTWARD THROUGH 36 HOURS, THEN SOUTH-
SOUTHEASTWARD. TC 19P IS EXPECTED TO WEAKEN AS DRY AIR CONTINUES TO
BE ENTRAINED INTO IT AND IT MOVES INTO INCREASING VERTICAL WIND
SHEAR. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 101200Z IS 13 FEET. NEXT

TROPICAL CYCLONE 19P HAS BEEN RELOCATED FURTHER EAST BASED ON
CURRENT VISIBLE IMAGERY AND A MICROWAVE IMAGER PASS (102206Z1).
TROPICAL CYCLONE 19P HAS TRACKED EASTWARD AT 9 KNOTS OVER THE PAST
6 HOURS UNDER THE STEERING INFLUENCE OF THE SUBTROPICAL RIDGE TO
THE NORTH. THE WARNING POSITION IS BASED ON 102330Z9 VISIBLE
SATELLITE IMAGERY AND THE 102206Z1 MICROWAVE IMAGER PASS. THE
WARNING INTENSITY IS BASED ON CURRENT SATELLITE INTENSITY ESTIMATES
OF 35 KNOTS. ANIMATED INFRARED AND VISIBLE SATELLITE IMAGERY
INDICATE STRONG UPPER-LEVEL OUTFLOW TO THE EAST AND AN OVERALL
WEAKENING OF THE CONVECTION OVER THE PAST THREE HOURS. ANIMATED
WATER VAPOR IMAGERY INDICATES A LARGE AREA OF SUBSIDENCE SOUTHWEST
OF THE SYSTEM. SOUTHERLY FLOW FROM THIS SUBSIDENCE AREA IS
ENTRAINING DRY AIR INTO THE LOWER AND MID LEVELS OF TC 19P. OVER
THE NEXT 12 HOURS, TROPICAL CYCLONE 19P IS FORECAST TO BEGIN MOVING
SOUTHEASTERLY AS IT GETS PICKED UP BY THE STEERING INFLUENCE OF THE
SUBTROPICAL RIDGE TO THE EAST. AFTERWARDS, TC 19P SHOULD BEGIN A
MORE SOUTHWARD TRACK AND ACCELERATE AS IT MOVES THROUGH THE ALREADY
ESTABLISHED TROUGH. TC 19P IS EXPECTED TO WEAKEN AS DRY AIR
CONTINUES TO BE ENTRAINED INTO IT AND IT MOVES INTO INCREASING
VERTICAL WINDSHEAR. TC 19P IS EXPECTED TO DISSIPATE AS A
SIGNIFICANT TROPICAL CYCLONE BY THE 48 HOUR POSITION. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 110000Z2 IS 13 FEET. NEXT WARNINGS AT

TROPICAL CYCLONE 19P HAS TRACKED TOWARDS THE SOUTH-SOUTHEAST AT 13
KNOTS DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON
021130Z7 INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED
ON 021130Z7 SATELLITE CURRENT INTENSITY ESTIMATES OF T3.0 (45
KNOTS). TC 19P HAS ACCELERATED TOWARDS THE SOUTH-SOUTHEAST UNDER
THE INCREASED STEERING FLOW OF THE SUBTROPICAL RIDGE TO THE EAST.
THIS STEERING FLOW IS EXPECTED TO REMAIN INTACT AND CONTINUE TO
TRACK TC 19P TOWARDS THE SOUTH-SOUTHEAST DURING THE FIRST 36 HOURS.
AFTERWARDS, THE SYSTEM IS FORECAST TO TRACK MORE SOUTHEASTWARD AS
IT MOVES AROUND THE SOUTHWEST PERIPHERY OF THE SUBTROPICAL RIDGE.
TC 19P HAS INTENSIFIED AND APPEARS MORE SYMMETRIC AROUND THE CENTER
OF CIRCULATION. THIS INTENSIFICATION IS FORECAST TO CONTINUE
THROUGHOUT THE FIRST 12 HOURS. AFTERWHICH, TC 19P IS FORECAST TO
BEGIN TO WEAKEN AS THE SYSTEM ENCOUNTERS INCREASED SHEAR AND MIXES
WITH DRIER AIR ASSOCIATED WITH THE SUBTROPICAL RIDGE. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 111200Z IS 14 FEET. NEXT WARNINGS AT

121730Z4 INFRARED INTENSITY ESTIMATE OF 25 KNOTS AUGMENTED BY
121153Z3 SCATTEROMETER DATA. WIND RADII HAVE BEEN ADDED BASED ON
THE SCATTEROMETER DATA. TROPICAL CYCLONE 19P (ELLA) IS FORECAST TO
CONTINUE MOVING SOUTH-SOUTHEASTWARD THROUGH 12 HOURS THEN MOVE
SOUTHWARD UNDER THE ENVIRONMENTAL STEERING INFLUENCE OF A MID-LEVEL
RIDGE TO THE EAST. TC 19P (ELLA) IS EXPECTED TO SLOWLY WEAKEN
UNDER THE INFLUENCE OF WESTERLY VERTICAL WIND SHEAR AND MOVEMENT
OVER COOLER SEA SURFACE TEMPERATURES. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 121800Z2 IS 15 FEET. REFER TO WWPWPN30 PGFW FOR
ADDITIONAL SEA HEIGHT INFORMATION. NEXT WARNINGS AT 130300Z7 (DTG
130151Z1), 130900Z3 (DTG 130751Z7), 131500Z0 (DTG 131351Z4) AND

TROPICAL CYCLONE 19P (ELLA) CONTINUES TO MOVE SOUTH-SOUTHEASTWARD
IN THE SOUTH PACIFIC OCEAN. THE LOW-LEVEL CIRCULATION CENTER HAS
BECOME PARTLY EXPOSED DURING THE PAST 06 HOURS DUE TO WESTERLY
VERTICAL WIND SHEAR. THE WARNING POSITION AND INTENSITY ARE BASED
ON 122330Z1 VISIBLE AND INFRARED SATELLITE INTENSITY ESTIMATES OF
25 KNOTS AND EXTRAPOLATION FROM 121153Z3 SCATTEROMETER DATA. THERE
IS NO SIGNIFICANT CHANGE TO FORECAST REASONING. TC 19P (ELLA) IS
EXPECTED TO TRACK SOUTHWARD IN ENVIRONMENTAL STEERING FLOW FROM A
LOW-TO MID-LEVEL RIDGE TO THE EAST. THIS SYSTEM IS ANTICIPATED TO
CONTINUE WEAKENING DUE TO VERTICAL SHEAR AND COOLER SEA SURFACE
TEMPERATURES, DISSIPATING BY 36 HOURS. MAXIMUM SIGNIFICANT WAVE

REMARKS:
130900Z3 POSITION NEAR 25.1S8 170.3E1.
TROPICAL CYCLONE 19P (ELLA) CONTINUES TO MOVE SOUTHEASTWARD
IN THE SOUTH PACIFIC OCEAN. THE WARNING POSITION AND INTENSITY ARE
BASED ON 130530Z2 VISIBLE AND INFRARED SATELLITE IMAGERY WITH
CURRENT INTENSITY ESTIMATES OF 30 KNOTS AND 130000Z4 SHIP AND
SYNOPTIC DATA REPORTS OF 20 KNOTS 200 NM OF THE 130600Z0 WARNING
POSITION. HOWEVER,THE INTENSITY IS CONSISTENT WITH THE PREVIOUS
FORECAST AS THE LOW LEVEL CIRCULATION CENTER HAS MOVED BACK UNDER
THE STRONG CONVECTION.THEN, TC 19P SHOULD WEAKEN AS THE VERTICAL
WIND SHEAR INCREASES. TC 19P (ELLA) IS EXPECTED TO TRACK SOUTHWARD
WITHIN THE ENVIRONMENTAL STEERING FLOW FROM A LOW-TO MID-LEVEL

REMARKS:
132100Z7 POSITION NEAR 25.7S4 170.4E2.
TROPICAL CYCLONE 19P (ELLA) IS MOVING SOUTH-SOUTHEASTWARD AT 06
KNOTS IN THE SOUTH PACIFIC OCEAN. ANIMATED INFRARED IMAGERY
INDICATES DEEP CONVECTION PREVIOUSLY ASSOCIATED WITH THIS SYSTEM
HAS DISSIPATED DUE TO MODERATE WESTERLY VERTICAL WIND SHEAR. THE
LOW-LEVEL CIRCULATION APPEARS TO HAVE SLOWED AND IS BEING STEERED
BY LOW-LEVEL NORTHWESTERLY WIND FLOW. THE WARNING POSITION AND
INTENSITY ARE BASED ON 131730Z5 INFRARED SATELLITE INTENSITY
ESTIMATES OF 25 KNOTS AND 30 KNOTS. THERE IS NO SIGNIFICANT CHANGE
TO FORECAST REASONING. TC 19P (ELLA) IS FORECAST TO CONTINUE MOVING
SLOWLY SOUTH-SOUTHEASTWARD AND DISSIPATE WITHIN 24 HOURS DUE TO
MODERATE VERTICAL SHEAR AND COOLER SEA SURFACE TEMPERATURES.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 131800Z3 IS 14 FEET. THIS IS THE
FINAL WARNING ON THIS SYSTEM BY THE JOINT TYPHOON WARNING CENTER
(NAVPACMETOCCEN PEARL HARBOR HI). THE SYSTEM WILL BE CLOSELY
MONITORED FOR SIGNS OF REGENERATION. REFER TO TROPICAL CYCLONE 21S
WARNINGS (WTXS31 PGTW) FOR SIX-HOURLY UPDATES.//
