JTWC評級Low
   (1) AN AREA OF CONVECTION HAS PERSISTED NEAR 11.2N 68.9E,
APPROXIMATELY 812 NM SOUTHEAST OF MASIRAH ISLAND, OMAN. ANIMATED
ENHANCED INFRARED SATELLITE IMAGERY DEPICTS A BROAD AREA OF
CONVECTION WITH NO DEFINED CIRCULATION CENTER. A PARTIAL 181546Z
METOPA-A 89GHZ IMAGE FURTHER DEPICTS POCKETS OF WEAK CONVECTION TO
THE SOUTH AND EAST OF THE 12Z BEST TRACK POSITION. UPPER LEVEL
ANALYSIS INDICATES BROAD, DIFFLUENT, SOUTHERLY FLOW ALOFT. THIS,
COUPLED WITH MARGINAL VERTICAL WIND SHEAR (10-20 KNOTS) DEPICT A
MARGINAL ENVIRONMENT FOR DEVELOPMENT, HOWEVER WARM (29-30 CELSIUS)
SEA SURFACE TEMPERATURES ARE FAVORABLE. GLOBAL MODELS ARE IN GOOD
AGREEMENT THAT 97A WILL CONTINUE TO SLOWLY CONSOLIDATE AS IT TRACKS
WESTWARD THROUGH TAU 24, HOWEVER THE WIND FIELDS ARE EXPECTED TO
REMAIN BELOW 25 KNOTS DURING THIS TIME.  MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1006 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.

JTWC24/0300Z發布TCFA
WTIO21 PGTW 240300
MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/TROPICAL CYCLONE FORMATION ALERT (INVEST 97A)//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
080 NM EITHER SIDE OF A LINE FROM 15.6N 72.0E TO 16.0N 66.7E
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 23 TO 28 KNOTS. METSAT
IMAGERY AT 240000Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 15.6N 70.5E. THE SYSTEM IS MOVING EAST-SOUTHEASTWARD AT 04
KNOTS.
2. REMARKS: THE AREA OF CONVECTION (INVEST 97A) PREVIOUSLY LOCATED
NEAR 15.8N 70.1E IS NOW LOCATED NEAR 15.6N 70.5E, APPROXIMATELY 243
NM SOUTHWEST OF MUMBAI, INDIA. ANIMATED ENHANCED INFRARED SATELLITE
IMAGERY SHOWS FLARING CONVECTION TO THE NORTH OF A CONSOLIDATING
LOW-LEVEL CIRCULATION CENTER (LLCC) WITH FORMATIVE BANDING TO THE
SOUTH AND WEST. A 231659 ASCAT-B IMAGE DEPICTS THIS TIGHTENING LLCC
WITH A LARGE BAND OF 25 KT WINDS SOUTH OF THE LLCC WITH POCKETS OF 30
KT WINDS 140 NM FROM THE CIRCULATION. UPPER-LEVEL ANALYSIS REVEALS
DECENT POLEWARD OUTFLOW WITH THE SYSTEM CURRENTLY UNDER FAVORABLE
VERTICAL WIND SHEAR (VWS) (5-10 KTS). HOWEVER, JUST TO THE WEST OF
THE SYSTEM IS STRONG VWS REACHING 25-30 KTS OVER THE CENTRAL ARABIAN
SEA. NUMERICAL MODEL GUIDANCE INDICATES STEADY INTENSIFICATION TO 35
KTS IN THE NEXT 24 HOURS. TRACK GUIDANCE INITIALLY SLOWLY TRACKS THE
SYSTEM TO THE EAST, HOWEVER ALL MODELS THEN REVERSE THE TRACK BETWEEN
TAUS 24 AND 72 TO TRACK WESTWARD INTO THE ARABIAN SEA. MAXIMUM
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 23 TO 28 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 HIGH.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
250300Z.//

氣旋強度達到了Cat.4
這張底層有機會強度上到Cat.5的可能性
