REMARKS:
262100Z POSITION NEAR 14.9S 168.8E.
26NOV19. TROPICAL CYCLONE 01P (RITA), LOCATED APPROXIMATELY 177 NM
NORTH OF PORT VILA, VANUATU, HAS TRACKED SOUTHWESTWARD AT 07 KNOTS
OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY
DEPICTS AN EXPOSED LOW-LEVEL CIRCULATION CENTER WITH NO CONVECTION
ASSOCIATED WITH THE SYSTEM. THE INITIAL POSITION IS PLACED WITH FAIR
CONFIDENCE BASED ON THIS EXPOSED LLCC. INITIAL INTENSITY OF 35 KNOTS
IS BASED ON THE PGTW/KNES DVORAK CURRENT INTENSITY ESTIMATES OF 2.0
(30 KNOTS). ENVIRONMENTAL ANALYSIS INDICATES THAT THE SYSTEM IS
TRANSITING AN INCREASINGLY UNFAVORABLE ENVIRONMENT AS DRY AIR WRAPS
INTO THE SYSTEM WITH MARGINAL VERTICAL WIND SHEAR (15-25KTS) AND VERY
MINIMAL UPPER-LEVEL OUTFLOW. AS 01P TRACKS SLOWLY SOUTHWEST IT WILL
FURTHER WEAKEN AND DISSIPATE OVER WATER BY TAU 12. THIS IS THE FINAL
WARNING ON THIS SYSTEM BY THE JOINT TYPHOON WRNCEN PEARL HARBOR HI.
THE SYSTEM WILL BE CLOSELY MONITORED FOR SIGNS OF REGENERATION.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 261800Z IS 11 FEET.//

REMARKS:
250300Z POSITION NEAR 12.1S 169.7E.
25NOV19. TROPICAL CYCLONE (TC) 01P (RITA), LOCATED APPROXIMATELY 363
NM NORTH-NORTHEAST OF PORT VILA, VANUATU, HAS TRACKED SOUTH-
SOUTHEASTWARD AT 07 KNOTS (KTS) OVER THE PAST SIX HOURS. THERE IS
HIGH CONFIDENCE IN THE INITIAL POSITION BASED ON A 13 NM CLOUD-
FILLED EYE IN ANIMATED ENHANCED INFRARED SATELLITE IMAGERY AND
EXTRAPOLATION FROM A 242150Z METOP-B ASCAT PASS. THE 65 KT INITIAL
INTENSITY IS CONSISTENT WITH THE PGTW DVORAK CURRENT INTENSITY
ESTIMATE OF T4.0 (65 KTS). GOOD POLEWARD OUTFLOW, LOW (5-10 KT)
VERTICAL WIND SHEAR, AND WARM (28-29 CELSIUS) SEA SURFACE
TEMPERATURE SUPPORT INTENSIFICATION. TC 01P IS TRACKING ALONG THE
SOUTHWEST PERIPHERY OF A NORTHWEST-TO-SOUTHEAST ORIENTED SUBTROPICAL
RIDGE (STR) TO THE EAST. BY TAU 48, INTERACTION WITH A STR TO THE
SOUTHWEST WILL BEGIN TO SLOWLY TURN TC 01P WESTWARD. DIMINISHED
OUTFLOW AND INCREASING VWS WILL HALT INTENSIFICATION BY TAU 12 AND
STEADY WEAKENING WILL LEAD TO DISSIPATION BY TAU 96. NAVGEM IS THE
SOLE DETERMINISTIC MODEL SOLUTION SHOWING TC 01P GRADUALLY TURN
EASTWARD AFTER TAU 24. ALTHOUGH THE REMAINING GUIDANCE IS SIMILAR TO
THE JTWC TRACK FORECAST, SPREAD IS QUITE LARGE AS SEVERAL MEMBERS
STALL THE SYSTEM WHILE OTHERS ACCELERATE IT. THE JTWC TRACK FORECAST
FOLLOWS CLOSE TO CONSENSUS WITH LOW CONFIDENCE BASED ON HIGH
UNCERTAINTY IN THE TRACK GUIDANCE. MAXIMUM SIGNIFICANT WAVE HEIGHT
AT 250000Z IS 17 FEET. NEXT WARNINGS AT 250900Z, 251500Z, 252100Z
AND 260300Z.//

REMARKS:
240300Z POSITION NEAR 10.4S 168.3E.
24NOV19. TROPICAL CYCLONE (TC) 01P (ONE), LOCATED APPROXIMATELY 450
NM NORTH OF PORT VILA, VANUATU, HAS TRACKED SOUTH-SOUTHEASTWARD AT
05 KNOTS (KTS) OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY REVEALS SPIRAL RAIN BANDS WRAPPING UNDER DEEP
CENTRAL CONVECTION THAT IS OBSCURING THE LOW LEVEL CIRCULATION
CENTER (LLCC). SUPPORTED BY A 232209Z MHS 89 GHZ MICROWAVE IMAGE
THAT SUGGESTS THE LLCC IS ON THE EQUATORWARD SIDE OF THE DEEP
CONVECTION, THERE IS FAIR CONFIDENCE IN THE INITIAL POSITION. THE
INITIAL INTENSITY OF 35 KTS IS CONSISTENT WITH THE PGTW DVORAK
CURRENT INTENSITY ESTIMATE OF T2.5 (35 KTS). THE ENVIRONMENT, WITH
LOW (10-15 KT) VERTICAL WIND SHEAR (VWS), EXCELLENT POLEWARD
OUTFLOW, AND WARM (29-30 CELSIUS) SEA SURFACE TEMPERATURE, IS
FAVORABLE. TC 01P IS TRACKING ALONG THE SOUTHWEST PERIPHERY OF A
NORTHWEST-TO-SOUTHEAST ORIENTED SUBTROPICAL RIDGE (STR). FOR THE
DURATION OF THE FORECAST, THE AFOREMENTIONED STR WILL STEER TC 01P
GENERALLY SOUTHEASTWARD. MODEL SOLUTIONS SUGGEST TWO DISTINCT
SCENARIOS ON THE TRACK OF TC 01P. NAVGEM AND ECMWF SHOW THE SYSTEM
CONTINUING TO TRACK SOUTHEASTWARD FOR THE DURATION OF THE FORECAST
PERIOD. THE OTHER MODELS SUGGEST THE SYSTEM WILL STALL AFTER ABOUT
TAU 48. THE JTWC TRACK FORECAST FOLLOWS THE NAVGEM AND ECMWF
SOLUTION. WITH THAT TRACK, THE SYSTEM WILL ENCOUNTER STRONG VWS
AFTER TAU 48 AND SHOULD DISSIPATE BY TAU 120. IF TC 01P STALLS AS
DEPICTED BY THE OTHER MODELS, VWS WILL REMAIN SOMEWHAT FAVORABLE AND
THE INTENSITY SHOULD WEAKEN MORE SLOWLY. BASED ON HIGH UNCERTAINTY
IN THE GUIDANCE BEYOND TAU 48, THERE IS LOW CONFIDENCE IN THE JTWC
TRACK FORECAST. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 240000Z IS 9
FEET. NEXT WARNINGS AT 240900Z, 241500Z, 242100Z AND 250300Z.//

FMS判定23/06Z升格為熱帶低壓,定強25kts。
Tropical Disturbance Summary For area Equator to 25S, 160E to 120W
ISSUED FROM RSMC NADI Nov 230917 UTC.

TROPICAL DEPRESSION 01F CENTRE 1002HPA WAS LOCATED NEAR 8.2S 167.6E
AT 230600 UTC. POSITION POOR BASED ON HR HIWARI EIR AND VIS IMAGERY
AND PERIPHERAL SURFACE REPORTS. TD01F SLOW MOVING.
MAXIMUM 10-MINUTE AVERAGE WINDS NEAR THE CENTRE ESTIMATED AT ABOUT 25
KNOTS.

POTENTIAL FOR THIS SYSTEM TO DEVELOP INTO A TROPICAL CYCLONE IN THE
NEXT 24 TO 48 HOURS IS HIGH.
TROPICAL DISTURBANCE ADVISORY NUMBER A2 ISSUED FROM RSMC NADI
Nov 231406 UTC.

TROPICAL DEPRESSION 01F CENTRE 1002HPA WAS LOCATED NEAR 9.4S 168.0E
AT 231200 UTC. POSITION POOR BASED ON HR HIMAWARI EIR AND VIS
IMAGERY AND PERIPHERAL SURFACE REPORTS. TD01F MOVING SOUTH-SOUTHEAST
AT ABOUT 13 KNOTS.
MAXIMUM 10-MINUTE AVERAGE WINDS NEAR THE CENTRE ESTIMATED AT ABOUT 25
KNOTS.

EXPECT CLOCKWISE WINDS UP TO 40 KNOTS WITHIN 60 TO 120 NAUTICAL MILES
AWAY FROM THE CENTER IN THE SECTORS FROM NORTHEAST THROUGH SOUTH TO
SOUTHWEST DEVELOPING IN THE NEXT 06 TO 12 HOURS.

TD01F HAS LLCC EXPOSED IN THE LAST 3 HOURS BUT CONVECTIVE BAND TO
NORTH HAS PERSISTED AND IS TRYING TO WRAP ONTO LLCC. TD01F LIES UNDER
A MODERATE DIFFLUENT REGION WITH LOW WIND SHEAR. SST IS AROUND 30
DEGREE CELSIUS. TD01F IS CURRENTLY BEING STEERED SOUTH ALONG THE
PERIPHERY OF A MID-LEVEL SUBTROPICAL RIDGE LOCATED TO THE EAST OF THE
SYSTEM.
GLOBAL MODELS AGREE ON A SOUTHWARDS TRACK WITH SOME INTENSIFICATION.
DVORAK ANALYSIS BASED ON 0.2/0.3 WRAP ON LOG 10 SPIRAL WHICH YIELDS A
DT OF 2.0. MET AND PAT AGREE WITH DT. FT BASED ON DT. THUS, YIELDS
T2.0/2.0/D0.5/24HRS.

FORECASTS :
AT 12 HRS VALID AT 240000 UTC 10.2S 168.9E MOV SE AT 06 KT WITH 30 KT
CLOSE TO CENTRE
AT 24 HRS VALID AT 241200 UTC 11.5S 169.6E MOV SE AT 07 KT WITH 30 KT
CLOSE TO CENTRE

OUTLOOK :
AT 36 HRS VALID AT 250000 UTC 12.7S 170.0E MOV SSE AT 06 KT WITH 35
KT CLOSE TO CENTRE
AT 48 HRS VALID AT 251200 UTC 13.7S 170.1E MOV SSE AT 06 KT WITH 45
KT CLOSE TO CENTRE

THE NEXT TROPICAL DISTURBANCE ADVISORY ON TROPICAL DEPRESSION 01F
WILL BE ISSUED AROUND 232000 UTC.

MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/TROPICAL CYCLONE FORMATION ALERT//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
150 NM EITHER SIDE OF A LINE FROM 7.6S 166.0E TO 9.8S 169.7E
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 230000Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 7.7S 166.3E. THE SYSTEM IS MOVING EAST-SOUTHEASTWARD AT 07
KNOTS.
2. REMARKS:
AN AREA OF CONVECTION (INVEST 90P), PREVIOUSLY LOCATED NEAR 7.1S
163.4E, IS NOW LOCATED NEAR 7.7S 166.3E,  APPROXIMATELY 380 NM EAST-
NORTHEAST OF HONIARA, SOLOMON ISLANDS. ANIMATED MULTISPECTRAL
IMAGERY DEPICTS CONVECTIVE BANDING WRAPPING OVER A LOW LEVEL
CIRCULATION CENTER EVIDENT BY A 22229Z METOP-B 89GHZ SATELLITE
IMAGE. THE ENVIRONMENT PROVIDES FOR MODERATE DEVELOPMENT WITH WARM
(29-30C) SEA SURFACE TEMPERATURES, LOW TO MODERATE (10-20KTS)
VERTICAL WIND SHEAR, AND DIFFLUENCE ALOFT. GLOBAL MODELS ARE IN GOOD
AGREEMENT THAT DEVELOPMENT INTO WARNING STATUS IS LIKELY BY TAU 24.
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 KNOTS.
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1004 MB. THE
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS HIGH.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
240330Z.//
