(As is )

WTIO21 PGTW 210730
MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/TROPICAL CYCLONE FORMATION ALERT//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
110 NM EITHER SIDE OF A LINE FROM 15.5N 91.2E TO 18.5N 92.6E
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 210530Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 16.1N 91.4E. THE SYSTEM IS MOVING NORTHWARD AT 06 KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 14.8N 
91.5E, IS NOW LOCATED NEAR 16.1N 91.4E, APPROXIMATELY 375 NM SOUTH 
OF CHITTAGONG, BANGLADESH. ANIMATED MULTISPECTRAL SATELLITE IMAGERY 
DEPICTS IMPROVED DEEP CONVECTIVE BANDING ASSOCIATED WITH A 
CONSOLIDATING LOW-LEVEL CIRCULATION CENTER (LLCC). A 210454Z METOP-B 
MICROWAVE IMAGE REVEALS AN ORGANIZING SYSTEM WITH THE BULK OF THE 
DEEP CONVECTION OVER THE SOUTHERN PERIPHERY WRAPPING INTO THE LLCC. 
A 210357Z ASCAT PASS SHOWS AN ELONGATED CIRCULATION WITH 35 TO 40 
KNOT WINDS OVER THE SOUTHWEST QUADRANT WITH WEAKER WINDS (15 TO 20 
KNOT) OVER THE NORTHERN SEMI-CIRCLE. WARM SEA SURFACE TEMPERATES IN 
THE AREA ARE CONDUCIVE FOR FURTHER DEVELOPMENT. UPPER-LEVEL ANALYSIS 
INDICATES THE DISTURBANCE IS LOCATED IN AN AREA OF MODERARE VERTICAL 
WIND SHEAR (20 KNOTS) OFFSET BY GOOD OUTFLOW. MAXIMUM SUSTAINED 
SURFACE WINDS ARE ESTIMATED AT 25 TO 30 KNOTS. MINIMUM SEA LEVEL 
PRESSURE IS ESTIMATED TO BE NEAR 1004 MB. DUE TO INCREASED 
CONSOLIDATION OF THE LOW-LEVEL SIGNATURE AND IMPROVING ENVIRONMENTAL 
CONDITIONS, 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 
220730Z.//
