REF/A/RMG/NAVPACMETOCCEN PEARL HARBOR HI/181151Z JAN 01//
AMPN/REF IS TROPICAL CYCLONE FORMATION ALERT (WTXS21 PGTW 181200)//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
A 120 NM RADIUS OF 15.0S6 83.6E7 WITHIN THE NEXT 06 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 190530Z8 INDICATES THAT A
CIRCULATION CENTER IS LOCATED NEAR 14.3S8 84.8E0. THE SYSTEM IS
MOVING SOUTHWESTWARD AT 10 KNOTS.
2. REMARKS:
THIS SUPERSEDES REF A.
THE TROPICAL DISTURBANCE IN THE SOUTH INDIAN OCEAN, HAS SHOWN
SOME IMPROVEMENT IN ORGANIZATION OVER THE PAST 12 HOURS. ANIMATED
SATELLITE IMAGERY INDICATES THE LOW LEVEL CIRCULATION CENTER
(LLCC) HAS BEGUN TO MOVE BENEATH THE CONVECTION. A RECENT
QUICKSCATT PASS INDICATES INCREASED WIND SPEEDS AT THE SURFACE.
UW-CIMSS VERTICAL WIND SHEAR PRODUCT INDICATES THE SYSTEM REMAINS
UNDER WEAK VERTICAL WIND SHEAR WITH IMPROVING UPPER-LEVEL
OUTFLOW. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS GOOD.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
200630Z1.//

192100Z3 POSITION NEAR 15.2S8 83.3E4.
TROPICAL CYCLONE (TC) 06S (CHARLY) HAS DEVELOPED APPROXIMATELY 800
NM SOUTHEAST OF DIEGO GARCIA OVER THE SOUTH INDIAN OCEAN. TROPICAL
CYCLONE (TC) 06S HAS TRACKED SOUTHWESTWARD AT 07 KNOTS DURING
THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON 191730Z1 INFRARED
SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON SATELLITE
CURRENT INTENSITY ESTIMATES OF 30 TO 45 KNOTS. ANIMATED INFRARED
SATELLITE IMAGERY INDICATES THAT TC 06S HAS IMPROVED ORGANIZATION
OVER THE PAST 12 HOURS WITH A WEAK CONVECTIVE BAND DEVELOPING SOUTH-
SOUTHEAST OF THE LOW-LEVEL CIRCULATION CENTER (LLCC). A 191125Z9
TROPICAL RAINFALL MEASURING MISSION PASS DEPICTED A WELL-DEFINED
LLCC WITH A CONVECTIVE BAND WRAPPING INTO THE WESTERN QUADRANT.
IMAGERY ALSO SHOWS THAT CONVECTION HAS CYCLED AS THE SYSTEM
CONSOLIDATES. ANIMATED WATER VAPOR IMAGERY SHOWS IMPROVED OUTFLOW,
ESPECIALLY IN THE SOUTHERN SEMI-CIRCLE, WITH A NORTHWESTERLY JET
ENHANCING THE OUTFLOW. A LOW-MID LEVEL HIGH, CENTERED SOUTH-
SOUTHEAST OF TC 06S AT APPROXIMATELY 33S6 91E0, IS PROVIDING THE
DOMINANT STEERING FLOW. THE RIDGE IS EXPECTED TO BUILD WESTWARD AND
STRENGTHEN THROUGH THE FORECAST PERIOD, WHICH WILL PROVIDE A
GENERALLY WESTWARD STEERING INFLUENCE AFTER 12-24 HOURS. THE SYSTEM
SHOULD INTENSIFY AT A CLIMATOLOGICAL RATE THROUGH THE PERIOD.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 191800Z9 IS 10 FEET. THIS WARNING

BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 45 TO 55 KNOTS. A
200330Z8 SPECIAL SENSOR MICROWAVE IMAGER (SSM/I) PASS DEPICTED A
PRIMARY BAND WRAPPING FROM THE NORTHEAST TO WEST QUADRANTS OF THE
LOW-LEVEL CIRCULATION CENTER (LLCC). ANIMATED WATER VAPOR IMAGERY
SHOWS GOOD OUTFLOW, AND THE 200 MB ANALYSIS INDICATES THE SYSTEM IS
UNDER THE UPPER LEVEL RIDGE AXIS. TC 06S IS CURRENTLY TRACKING
WITHIN A WEAKNESS IN THE MID-LEVEL RIDGE CREATED BY A MID-LAT TROUGH
POLEWARD OF THE SYSTEM. THE RIDGE IS EXPECTED TO BUILD IN BEHIND THE
TROUGH AND STRENGTHEN THROUGH THE FORECAST PERIOD. THIS FEATURE
