1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION (INVEST 96W) HAS PERSISTED NEAR 7.4N
131.6W, APPROXIMATELY 184 NM WEST OF PALAU. ANIMATED ENHANCED
INFRARED (EIR) SATELLITE IMAGERY AND 111923Z SSMIS 91 GHZ MICROWAVE
IMAGE DEPICT CONSOLIDATED AND FLARING CONVECTION OVER A WEAK,
PARTIALLY EXPOSED LOW LEVEL CIRCULATION. INVEST 96W IS IN A
FAVORABLE ENVIRONMENT WITH VERY WARM (30-31C) SEA SURFACE
TEMPERATURE AND WEAK (05-10KT) VERTICAL WIND SHEAR. GLOBAL MODELS
ARE IN MODERATE AGREEMENT THAT INVEST 96W WILL GRADUALLY INTENSIFY
AS IT TRACKS WESTWARD OVER THE NEXT 24-72 HOURS. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 1003 MB. THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS UPGRADED TO LOW.

JTWC06Z評級提升至Medium
   (1) THE AREA OF CONVECTION (INVEST 96W) PREVIOUSLY LOCATED
NEAR 7.4N 131.6E IS NOW LOCATED NEAR 7.6N 131.1E, APPROXIMATELY 210
NM WEST OF PALAU. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI)  
DEPICTS BROAD LOWER LEVEL TURNING MARGINALLY DECOUPLED FROM A MORE
DEFINED UPPER LEVEL CIRCULATION. AN 112304Z ASCAT-A PASS REVEALS A
BROAD LOWER LEVEL CIRUCLATION WITH 15-20KT WINDS IN THE NORTHERN
PERIPHERY. INVEST 96W IS IN A FAVORABLE ENVIRONMENT WITH VERY WARM
(30-31C) SEA SURFACE TEMPERATURES, AND NEARLY RADIAL OUTFLOW
MARGINALLY OFFSET BY MODERATE (10-20KT) VERTICAL WIND SHEAR. GLOBAL
MODELS PREDICT THAT 96W WILL EXPERIENCE LITTLE TO NO INTENSIFICATION
AS IT PROPAGATES NORTHWESTWARD. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED
TO BE NEAR 1006 MB. DUE TO THE FAVORABLE ENVIRONMENT, THE POTENTIAL
FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE
NEXT 24 HOURS IS UPGRADED TO MEDIUM.

JTWC1600Z發布TCFA
WTPN22 PGTW 121600
MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/TROPICAL CYCLONE FORMATION ALERT (INVEST 96W)//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
120 NM EITHER SIDE OF A LINE FROM 6.6N 131.3E TO 8.7N 124.5E
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 18 TO 23 KNOTS. METSAT
IMAGERY AT 121200Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 6.8N 130.9E. THE SYSTEM IS MOVING WESTWARD AT 03 KNOTS.
2. REMARKS: ANIMATED ENHANCED INFRARED SATELLITE IMAGERY DEPICTS A
COMPACT AREA OF CONVECTION OBSCURING A WELL DEFINED LOW LEVEL
CIRCULATION THAT IS EVIDENT IN DATA FROM A 121302Z ASCAT-B PASS.
FURTHERMORE, THE SCATTEROMETRY DATA REVEALS 20-25 KTS WINDS ALONG
THE PERIPHERY OF THE CIRCULATION CENTER, WITH ISOLATED REGIONS OF
HIGHER WINDS IN THE EASTERN PORTION OF THE SEMICIRCLE. THE
ENVIRONMENT IS FAVORABLE FOR FURTHER INTENSIFICATION WITH LOW
(5-10 KTS) VERTICAL WIND SHEAR, WARM (27-28 CELSIUS) SEA SURFACE
TEMPERATURES AND MODEST DIVERGENCE SUPPORTED BY A POINT SOURCE
OVERHEAD. GLOBAL MODELS ARE IN GOOD AGREEMENT THAT THE SYSTEM WILL
GRADUALLY DEEPEN AND TRACK WESTWARD TOWARDS THE PHILIPPINE COAST.
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 131600Z.
