SUBJ/TROPICAL CYCLONE FORMATION ALERT 042121ZMAR03//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
A 125 NM RADIUS OF 11.5S7 78.4E9 WITHIN THE NEXT 06 TO 24 HOURS.
AVAILABLE DATA DOES NOT JUSTIFY ISSUANCE OF A NUMBERED TROPICAL
CYCLONE WARNING AT THIS TIME. WINDS IN THE AREA ARE ESTIMATED TO BE
25 TO 35 KNOTS. METSAT IMAGERY AT 041730Z5 INDICATES THAT A
CIRCULATION CENTER IS LOCATED NEAR 11.5S7 78.4E9. THE SYSTEM IS
QUASI-STATIONARY.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 11.6S8
78.5E0, IS NOW LOCATED NEAR 11.5S7 78.7E2, APPROXIMATELY 445 NM
SOUTHEAST OF DIEGO GARCIA. ANIMATED INFRARED SATELLITE IMAGERY AND A
041307Z5 SPECIAL SENSOR MICROWAVE IMAGER (SSM/I) PASS INDICATES DEEP
CONVECTION OVER A LOW LEVEL CIRCULATION CENTER (LLCC) HAS INCREASED
IN ORGANIZATION OVER THE PAST 6 HOURS. DEEP CONVECTION IS LOCATED
PRIMARILY WEST THROUGH SOUTHWEST OF THE LLCC. UPPER-LEVEL ANALYSIS
INDICATES WEAK TO MODERATE VERTICAL WIND SHEAR AND FAVORABLE
DIVERGENCE ALOFT OVER THE AREA. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 25 TO 35 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED
TO BE NEAR 1006 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE OVER THE NEXT 24 HOURS IS UPGRADED TO
GOOD.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
052130Z1.

REMARKS:
080300Z1 POSITION NEAR 13.9S3 71.0E8.
THE WARNING IS AMENDED BASED ON A RAPID INTENSIFICATION TREND,
GREATER THAN PREVIOUSLY FORECAST. TROPICAL CYCLONE (TC) 23S
(KALUNDE), LOCATED APPROXIMATELY 395 NM SOUTH-SOUTHWEST OF DIEGO
GARCIA, HAS TRACKED WEST-SOUTHWESTWARD AT 08 KNOTS DURING THE PAST 6
HOURS. THE WARNING POSITION IS BASED ON 072330Z5 ENHANCED INFRARED
SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON SATELLITE
CURRENT INTENSITY ESTIMATES OF 140 KNOTS. A 072318Z1 TROPICAL
RAINFALL MEASURING MISSION (TRMM) PASS REVEALS A 30 NM EYE. TC 23S
IS FORECAST TO CONTINUE ON A SOUTHWESTWARD TRACK THROUGH 48 HOURS
ABOVE THE MID-LEVEL SUBTROPICAL RIDGE SOUTHEAST OF THE SYSTEM. TC
23S IS EXPECTED TO CONTINUE INTENSIFICATION AT A CLIMATOLOGICAL RATE
IN A VERY FAVORABLE UPPER LEVEL ENVIRONMENT. THE AVAILABLE DYNAMIC
AIDS, CONSISTING OF NOGAPS, GFDN, NCEP AVIATION (AVN), AND THE UKMET
OFFICE (EGRR) MODELS ARE IN GOOD AGREEMENT. THIS FORECAST IS BASED
ON A CONSENSUS OF THE AVAILABLE MODELS AND PERSISTENCE. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 080000Z8 IS 25 FEET. NEXT WARNINGS AT
081500Z4 AND 090300Z2. REFER TO TROPICAL CYCLONE 21S (HARRIET)

REMARKS:
141500Z1 POSITION NEAR 25.1S8 65.4E5.
TROPICAL CYCLONE (TC) 23S (KALUNDE), LOCATED IN THE SOUTH INDIAN
OCEAN, HAS TRACKED SOUTHWARD AT 07 KNOTS OVER THE PAST 6 HOURS. THE
WARNING POSITION IS BASED ON 141130Z0 MULTISPECTRAL SATELLITE
IMAGERY. THE WARNING INTENSITY IS BASED ON SATELLITE CURRENT
INTENSITY ESTIMATES OF 45 AND 55 KNOTS. VISIBLE SATELLITE IMAGERY
REVEALS THE LOW LEVEL CIRCULATION CENTER IS FULLY EXPOSED WITH THE
DEEP CONVECTION SHEARED 90 NM TO THE SOUTHEAST. TC 23S IS FORECAST
TO CONTINUE ON A POLEWARD TRACK THROUGH THE FORECAST PERIOD, BELOW
THE AXIS OF THE SUBTROPICAL RIDGE LOCATED NORTHEAST OF THE SYSTEM.
TC 23S WILL CONTINUE TO WEAKEN AS THE SYSTEM ENCOUNTERS INCREASING
VERTICAL WIND SHEAR. TC 23S IS EXPECTED TO ULTIMATELY DISSIPATE AS A
SIGNIFICANT TROPICAL CYCLONE OVER WATER. THE AVAILABLE DYNAMIC AIDS,
CONSISTING OF NOGAPS, GFDN, NCEP AVIATION (AVN), AND UKMET OFFICE
(EGRR) ARE IN FAIR AGREEMENT. THIS FORECAST IS BASED ON A CONSENSUS
OF THE AVAILABLE DYNAMIC AIDS AND PERSISTENCE. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 141200Z8 IS 20 FEET. NEXT WARNINGS AT 150300Z9 AND
151500Z2. RELEASED BY CAPT KENDALL, USAF.//

REMARKS:
150300Z9 POSITION NEAR 26.4S2 65.6E7.
TROPICAL CYCLONE (TC) 23S (KALUNDE), LOCATED IN THE SOUTH INDIAN
OCEAN, HAS TRACKED SOUTH-SOUTHEASTWARD AT 05 KNOTS OVER THE PAST 6
HOURS. THE WARNING POSITION IS BASED ON 142330Z3 ENHANCED INFRARED
SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON SATELLITE
CURRENT INTENSITY ESTIMATES OF 45 AND 55 KNOTS. RECENT MICROWAVE AND
ANIMATED WATER VAPOR IMAGERY SUGGEST THE SYSTEM IS TRANSITIONING
INTO AN EXTRATROPICAL SYSTEM, WITH THE DEEP CONVECTION BEING
SHEARED TO THE SOUTHEAST. TC 23S IS FORECAST TO TRACK SOUTHEASTWARD
THROUGH THE FORECAST PERIOD. TC 23S WILL CONTINUE TO WEAKEN AS THE
SYSTEM ENCOUNTERS INCREASING VERTICAL WIND SHEAR. TC 23S IS EXPECTED
TO COMPLETE EXTRATROPICAL TRANSITION WITHIN THE NEXT 12 TO 24 HOURS.
THE AVAILABLE DYNAMIC AIDS, CONSISTING OF NOGAPS, GFDN, NCEP
AVIATION (AVN), AND UKMET OFFICE (EGRR) ARE IN FAIR AGREEMENT. THIS
FORECAST IS BASED ON A CONSENSUS OF THE AVAILABLE DYNAMIC AIDS AND

REMARKS:
151500Z2 POSITION NEAR 29.3S4 66.3E5.
TROPICAL CYCLONE (TC) 23S (KALUNDE), LOCATED IN THE SOUTH INDIAN
OCEAN, HAS TRACKED SOUTHWARD AT 13 KNOTS OVER THE PAST 6 HOURS. THE
WARNING POSITION IS BASED ON 151130Z1 VISIBLE SATELLITE IMAGERY. THE
WARNING INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES
OF 25 KNOTS. RECENT ANIMATED SATELLITE IMAGERY SUGGESTS THAT THE
INTENSITY IS SLIGHTLY HIGHER THAN DVORAK INTENSITY ESTIMATES GIVE
DUE TO THE FULLY EXPOSED LOW LEVEL CIRCULATION CENTER. THE IMAGERY
ALSO SUGGESTS THE SYSTEM IS DISSIPATING WHILE TRANSITIONING INTO AN
EXTRATROPICAL SYSTEM, WITH THE REMAINING DEEP CONVECTION CONFINED TO
THE SOUTHEAST QUADRANT. TC 23S IS FORECAST TO TRACK SOUTHWARD AND BE
EXTRATROPICAL IN 12 HOURS. THE AVAILABLE DYNAMIC AIDS, CONSISTING OF
NOGAPS, GFDN, NCEP AVIATION (AVN), AND UKMET OFFICE (EGRR) ARE IN
GOOD AGREEMENT. THIS FORECAST IS BASED ON A CONSENSUS OF THE
AVAILABLE DYNAMIC AIDS AND PERSISTENCE. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 151200Z9 IS 15 FEET. THIS IS THE FINAL WARNING ON THIS
SYSTEM BY THE JOINT TYPHOON WARNING CENTER (NAVPACMETOCCEN). THE
SYSTEM WILL BE CLOSELY MONITORED FOR SIGNS OF REGENERATION. RELEASED
BY CAPT LEEJOICE, USAF.//
