JTWC 28/18Z評級Low。
(1) AN AREA OF CONVECTION (INVEST 90A) HAS PERSISTED NEAR 2.6N
56.0E, APPROXIMATELY 646 NM EAST OF MOGADISHU, SOMALIA. ANIMATED
MULTISPECTRAL IMAGERY DEPICTS DISORGANIZED CONVECTION OVER A
PARTIALLY EXPOSED LOW LEVEL CIRCULATION, SUPPORTED BY A 281130Z
85GHZ SSMI SATELLITE IMAGE. ENVIRONMENTAL ANALYSIS INDICATES A
MARGINAL POTENTIAL FOR DEVELOPMENT WITH WARM (29-30C) SEA SURFACE
TEMPERATURE AND MARGINAL WESTWARD OUTFLOW OFFSET BY HIGH (20-30KTS)
LEVELS OF VERTICAL WIND SHEAR. GLOBAL MODELS SHOW SOME DEVELOPMENT
BETWEEN TAU 96 AND 120, AS THE CIRCULATION MAKES LANDFALL OVER
SOMALIA.  MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1005 MB.
THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS LOW.

JTWC02/0900Z發布TCFA
WTIO21 PGTW 020900
MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/TROPICAL CYCLONE FORMATION ALERT (INVEST 90A)//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
A 120 NM RADIUS OF 5.6N 57.0E 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 25 TO 30 KNOTS. METSAT IMAGERY AT 020830Z INDICATES THAT A
CIRCULATION CENTER IS LOCATED NEAR 5.6N 57.0E. THE SYSTEM IS
MOVING NORTHWARD AT 01 KNOTS.
2. REMARKS: THE AREA OF CONVECTION (INVEST 90A) PREVIOUSLY LOCATED
NEAR 5.2N 57.0E IS NOW LOCATED NEAR 5.6N 57.0E, APPROXIMATELY 500 NM
SOUTHEAST OF CAPE GUARDAFUI, SOMALIA. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY DEPICTS A CONSOLIDATING SYSTEM WITH FRAGMENTED
DEEP CONVECTIVE BANDING WRAPPING TIGHTLY INTO A DEFINED LOW-LEVEL
CIRCULATION CENTER (LLCC). A 020210Z WINDSAT 37GHZ IMAGE DEPICTS
MULTIPLE CONVECTIVE BANDS WRAPPING INTO A BROAD BUT DEFINED LLCC. A
020527Z ASCAT-B IMAGE SHOWS A SYMMETRIC CIRCULATION WITH A BAND OF
25-30 KNOT WINDS OVER THE WESTERN SEMICIRCLE. ENVIRONMENTAL ANALYSIS
REVEALS FAVORABLE CONDITIONS WITH ROBUST POLEWARD AND EQUATORWARD
OUTFLOW, LOW VERTICAL WIND SHEAR, AND WARM SST (28-29C) VALUES.
NUMERICAL MODEL GUIDANCE INDICATES A SLOW, POSSIBLY QUASI-
STATIONARY, POLEWARD TRACK OVER THE NEXT TWO DAYS WITH GRADUAL
INTENSIFICATION. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 25
TO 30 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1000
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
030900Z.//

改編ARB 05B
(B) DEEP DEPRESSION OVER SOUTHWEST ARABIAN SEA:
THE DEEP DEPRESSION OVER SOUTHWEST ARABIAN SEA REMAINED PRACTICALLY STATIONARY DURING
PAST 06 HOURS AND LAY CENTRED AT 0000 HRS UTC OF 04TH DECEMBER, 2019 NEAR LATITUDE 7.2°N AND
LONGITUDE 56.6°E OVER SOUTHWEST ARABIAN SEA, ABOUT 670 KM SOUTH-SOUTHEAST OF SOCOTRA
(41494) AND 930 KM EAST-SOUTHEAST OF BOSASO (63210). IT IS VERY LIKELY TO INTENSIFY INTO A
CYCLONIC STORM DURING NEXT 12 HOURS. IT IS VERY LIKELY TO MOVE NORTH-NORTHWESTWARDS FOR
SOME MORE TIME AND THEN RECURVE WEST-SOUTHWESTWARDS TOWARDS SOMALIA COAST DURING
NEXT 03 DAYS.
