JTWC 17Z評級提升至Medium，機構看好發展。

(2) AN AREA OF CONVECTION (INVEST 94P) HAS PERSISTED NEAR 10S
164E, APPROXIMATELY 238 NM EAST OF HONIARA, SOLOMON ISLANDS.
ANIMATED ENHANCED INFRARED SATELLITE IMAGERY AND A 281820Z SSMIS
91GHZ IMAGE DEPICTS A RAGGED ELONGATED LOW LEVEL CIRCULATION CENTER
(LLCC) THAT IS BECOMING MORE DEFINED, WITH FORMATIVE UPPER LEVEL
BANDING. OVERALL THE ENVIRONMENT IS FAVORABLE FOR DEVELOPMENT WITH
LOW VERTICAL WIND SHEAR (5-10 KNOTS), GOOD RADIAL OUTFLOW, AND WARM
SEA SURFACE TEMPERATURES (26-28 CELSIUS). MOST GLOBAL MODELS ARE IN
AGREEMENT ABOUT THE SYSTEM DEVELOPING WITHIN 36 TO 60 HOURS AND
TRACKING EASTWARD. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT
20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR
1001 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL
CYCLONE WITHIN THE NEXT 24 HOURS IS MEDIUM.

FMS 編號熱帶擾動03F。

TROPICAL DISTURBANCE TD03F CENTRE[1002HPA] WAS ANALYSED NEAR 09.8S
166.2E AT 282100 UTC SLOW MOVING. POSITION POOR BASED ON HIMAWARI 8
VIS IMAGERY.

DEEP CONVECTION OVER SUPPOSED LLCC WITH GOOD ORGANISATION. CYCLONIC
CIRCULATION EXTENDS UPTO 500HPA. SYSTEM LIES OF AN UPPER RIDGE WITH
GOOD OUTFLOW IN A MODERATE SHEARED ENVIRONMENT. SST AROUND 29 DEGREES
CELSIUS.

GLOBAL MODELS HAVE PICKED UP THE SYSTEM AND GRADUALLY MOVE IT IN A
SOUTHEAST DIRECTION WITH FURTHER INTENSIFICATION

POTENTIAL FOR THIS SYSTEM TO DEVELOP INTO A TROPICAL CYCLONE IN THE
NEXT 24 TO 36 HOURS IS LOW.

JTWC 09Z發布TCFA。

WTPS22 PGTW 300930
MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/TROPICAL CYCLONE FORMATION ALERT//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
165 NM EITHER SIDE OF A LINE FROM 11.0S 170.1E TO 16.6S 178.1E
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 300600Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 11.6S 171.2E. THE SYSTEM IS MOVING EAST-SOUTHEASTWARD AT 18
KNOTS.
2. REMARKS: THE AREA OF CONVECTION (INVEST 94P) PREVIOUSLY LOCATED
NEAR 11.0S 169.5E, IS NOW LOCATED NEAR 11.6S 171.2E, APPROXIMATELY
410 NM NORTH-NORTHEAST OF PORT VILA, VANUATU. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY AND A 300339Z SSMI F-15 85GHZ MICROWAVE IMAGE
DEPICT A BROAD AREA OF TURNING WITH POCKETS OF FLARING CONVECTION
LOCATED PRIMARILY TO THE NORTH. THE DISTURBANCE IS CURRENTLY LOCATED
IN AN AREA OF EXCELLENT POLEWARD DIVERGENCE, LOW TO MODERATE
VERTICAL WIND SHEAR (15-20 KNOTS), AND WARM SEA SURFACE TEMPERATURES
(27-29 CELSIUS). GLOBAL MODELS ARE IN AGREEMENT THAT THE SYSTEM WILL
CONTINUE TRACKING TO THE EAST OVER THE NEXT SEVERAL DAYS WITH
INTENSIFICATION LIKELY. 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
310930Z.

JTWC 06Z取消TCFA，評級降低至Low。

(1) THE AREA OF CONVECTION (INVEST 94P) PREVIOUSLY LOCATED
NEAR 13.5S 178.4E, IS NOW LOCATED NEAR 15.2S 179.9E, APPROXIMATELY
210 NM NORTHEAST OF NADI, FIJI. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY AND A 010305Z SSMI F-15 85GHZ MICROWAVE IMAGE DEPICTS A LOW
LEVEL CIRCULATION (LLC) WITH FLARING CONVECTION BECOMING SPARSER AND
MORE INCONSISTENT. THE DISTURBANCE IS CURRENTLY LOCATED IN AN AREA
OF STRONG POLEWARD OUTFLOW, MODERATE TO HIGH VERTICAL WIND SHEAR (25-
35 KNOTS), AND WARM SEA SURFACE TEMPERATURES (28-30 CELSIUS). GLOBAL
MODELS SHOW THAT IT WILL CONTINUE TO DRIFT SOUTHEAST AND IS UNLIKELY
TO INTENSIFY. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 25 TO
30 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 994 MB.
THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS DOWNGRADED TO LOW.
