SUBJ/TROPICAL CYCLONE FORMATION ALERT//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
115 NM EITHER SIDE OF A LINE FROM 12.5S 89.1E TO 12.6S 84.4E
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 IM-
AGERY AT 070130Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 12.5S 88.7E. THE SYSTEM IS MOVING WESTWARD AT 09 KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 12.5S
90.7E, IS NOW LOCATED NEAR 12.5S 88.7E, APPROXIMATELY 1100 NM EAST-
SOUTHEAST OF DIEGO GARCIA. RECENT METSAT IMAGERY DEPICTS DEEP CON-
VECTION BUILDING TO THE WEST OF AN INCREASINGLY CONSOLIDATED LOW
LEVEL CIRCULATION CENTER (LLCC). THE LLCC IS CONFIRMED BY SCATTER-
OMETRY OBSERVATIONS WHICH SHOW 25 TO 30 KNOT WINDS ASSOCIATED WITH
THE CIRCULATION. UPPER LEVEL ANALYSIS INDICATES THAT THE LLCC IS IN
A REGION OF MODERATE VERTICAL WIND SHEAR WHICH IS EXPECTED TO DE-
CREASE OVER THE NEXT 18 TO 24 HOURS. GOOD DIFFLUENCE ALOFT ASSOCIATED
WITH A STRONG UPPER-LEVEL RIDGE IS PROVIDING AN AMPLE OUTFLOW CHANNEL
FOR THE DISTURBANCE. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT
25 TO 30 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR
1001 MB. DUE TO THE IMPROVED CONSOLIDATION OF THE LLCC, IMPROVING
CONVECTION AND MORE FAVORABLE UPPER LEVEL ENVIRONMENT, THE POTENTIAL
FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT
24 HOURS IS UPGRADED TO GOOD.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
080200Z.

TROPICAL CYCLONE (TC) 23S (NONAME) LOCATED APPROXIMATELY 910 NM
EAST-SOUTHEAST OF DIEGO GARCIA, HAS TRACKED WEST-NORTHWESTWARD
AT 08 KNOTS OVER THE PAST 06 HOURS. TC 23S IS TRACKING ALONG
THE NORTHERN PERIPHERY OF A SUBTROPICAL RIDGE TO THE SOUTH OF
THE STORM. THE SYSTEM WILL CONTINUE A GENERALLY WESTWARD TO
WEST-SOUTHWESTWARD TRACK THROUGH THE FORECAST PERIOD. THE
SYSTEM HAS INTENSIFIED OVER THE PAST 12 HOURS AND SATELLITE
INTENSITY ESTIMATES SUPPORT THE INITIAL INTENSITY. THE STORM
WILL INTENSIFY SLOWLY THROUGH TAU 36 DUE TO MODERATE VERTICAL
WIND SHEAR. THE VERTICAL WIND SHEAR WILL DECREASE AFTER THIS
TIME AND THE STORM IS FORECAST TO INTENSIFY MORE STEADILY.
THE TRACK FORECAST IS CLOSE TO THE CONSENSUS OF THE DYNAMIC
AIDS THAT ARE IN GOOD AGREEMENT AND THE INTENSITY FORECAST
IS NEAR THE STATISTICAL GUIDANCE. THIS WARNING SUPERSEDES
AND CANCELS REF A, NAVPACMETOCCEN 070200Z FEB 08 TROPICAL
CYCLONE FORMATION ALERT (WTXS21 PGTW 070200) MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 071200Z IS 15 FEET. NEXT WARNINGS

INTENSITY ESTIMATES SUPPORT THE INITIAL INTENSITY. THE STORM
WILL INTENSIFY THROUGH TAU 48 DUE TO LIGHT VERTICAL WIND SHEAR
AND GOOD OUTFLOW. THE TRACK FORECAST IS CLOSE TO THE CONSENSUS
OF THE DYNAMIC AIDS THAT ARE IN GOOD AGREEMENT AND THE INTENSITY
FORECAST IS NEAR THE STATISTICAL GUIDANCE. FORECAST INTENSITIES
ARE HIGHER THAN THE PREVIOUS FORECAST DUE TO STRONGER THAN

INTENSITY OVER THE PAST 12 HOURS UNDER THE COMPETING INFLUENCES
OF FAVORABLE OCEAN HEAT CONTENT AND GOOD UPPER LEVEL DIFFLUENCE
AND UNFAVORABLE, INCREASING EASTERLY VERTICAL WIND SHEAR. TC 23S
IS EXPECTED TO INTENSIFY SLOWLY DURING THE NEXT 48 HOURS AS THE
SYSTEM APPROACHES THE AXIS OF A SYNTOPIC-SCALE UPPER LEVEL
ANTICYCLONE, WHICH SHOULD REDUCE VERTICAL WIND SHEAR AND ENHANCE
POLEWARD OUTFLOW. THE TRACK AND INTENSITY FORECASTS ARE CLOSE TO

REMARKS:
091500Z POSITION NEAR 15.0S 81.6E.
TROPICAL CYCLONE (TC) 23S (KAMBA) LOCATED APPROXIMATELY 715 NM SOUTH-
EAST OF DIEGO GARCIA, HAS TRACKED WEST-SOUTHWESTWARD AT 12 KNOTS OVER
THE PAST 06 HOURS. TC 23S CONTINUES TO TRACK ALONG THE NORTHWESTERN
PERIPHERY OF A SUBTROPICAL RIDGE TO THE SOUTHEAST OF THE STORM.
GENERALLY SOUTHWESTWARD MOTION ALONG THE PERIPHERY OF THE CURRENT
STEERING RIDGE IS EXPECTED TO CONTINUE THROUGH THE FORECAST PERIOD.
SATELLITE INTENSITY ESTIMATES FROM VARIOUS REPORTING AGENCIES INDI-
CATE THAT THE SYSTEM HAS INTENSIFIED SLIGHTLY OVER THE PAST 12 HOURS
IN RESPONSE TO DECREASING VERTICAL WIND SHEAR AND FAVORABLE OUTFLOW
ALOFT. THE STORM IS EXPECTED TO CONTINUE THIS SLOW INTENSIFICATION
TREND THROUGH TAU 24 AS UPPER LEVEL CONDITIONS REMAIN FAVORABLE BUT
ALONG-TRACK OCEAN HEAT CONTENT DECREASES. THERAFTER, THE STORM WILL
ENCOUNTER COOLER WATER AND INCREASING WESTERLY VERTICAL WIND SHEAR
ASSOCIATED WITH A MID-LATITUDE TROUGH CURRENTLY LOCATED TO THE
SOUTHWEST OF THE STORM. AS TC 23S CONTINUES POLEWARD TOWARD THE
BASE OF THIS TROUGH AND ENCOUNTERS COOLER WATER, THE FIRST STAGE
OF EXTRATROPICAL TRANSITION WILL BEGIN BY TAU 48. THE TRACK AND
INTENSITY FORECASTS REMAIN CLOSE TO THEIR RESPECTIVE NUMERICAL AND
STATISTICAL MODEL CONSENSUSES. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
091200Z IS 32 FEET. NEXT WARNINGS AT 100300Z AND 101500Z. REFER TO

101500Z POSITION NEAR 18.7S 78.5E.
TROPICAL CYCLONE (TC) 23S (KAMBA) LOCATED APPROXIMATELY 740 NM SOUTH-
SOUTHEAST OF DIEGO GARCIA, HAS TRACKED SOUTH-SOUTHWESTWARD AT 14
KNOTS OVER THE PAST 06 HOURS. TC 23S IS TRACKING POLEWARD ALONG THE
WESTERN PERIPHERY OF A SUBTROPICAL STEERING RIDGE TO THE EAST OF
THE SYSTEM. THIS GENERAL MOTION IS EXPECTED TO CONTINUE THROUGH THE
FORECAST PERIOD. SATELLITE INTENSITY ESTIMATES FROM VARIOUS REPORTING
AGENCIES INDICATE THAT THE SYSTEM HAS CONTINUED A SIGNIFICANT INTEN-
SIFICATION TREND OVER THE PAST 12 HOURS DUE TO LOW VERTICAL WIND
SHEAR, FAVORABLE OCEAN HEAT CONTENT, AND EXCELLENT DUAL CHANNEL OUT-
FLOW. THE STORM IS EXPECTED TO NEARLY MAINTAIN INTENSITY OR WEAKEN
ONLY SLIGHTLY OVER THE NEXT 12 HOURS AS AN APPROACHING MID-LATITUDE
TROUGH TO THE SOUTHWEST INTRODUCES INCREASING EASTERLY VERTICAL WIND
SHEAR. THEREAFTER, INCREASING VERTICAL WIND SHEAR, DECREASING OCEAN
HEAT CONTENT, AND SUPPRESSED EQUATORWARD OUTFLOW WILL DRIVE STEADIER
WEAKENING. BY TAU 48, INTERACTION WITH THE AFOREMENTIONED MID-LATI-
TUDE TROUGH AND PASSAGE OVER COOLER WATER WILL INDUCE THE FIRST
STAGE OF EXTRATROPICAL TRANSITION. THE TRACK FORECAST REMAINS CLOSE
TO THE NUMERICAL MODEL CONSENSUSES. THE TAU 24 THROUGH TAU 48
INTENSITY FORECAST IS HIGHER THAN THE STATISTICAL MODEL GUIDANCE TO
REFLECT A MORE PROBABLE WEAKENING TREND. MAXIMUM SIGNIFICANT WAVE

REMARKS:
111500Z POSITION NEAR 23.6S 78.0E.
TROPICAL CYCLONE (TC) 23S (KAMBA) LOCATED APPROXIMATELY 995 NM SOUTH-
SOUTHEAST OF DIEGO GARCIA, HAS TRACKED SOUTHWARD AT 11 KNOTS OVER THE
PAST 06 HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS A
RAPIDLY WEAKENING SYSTEM WITH A PARTIALLY-EXPOSED LOW-LEVEL CIRCUL-
ATION CENTER DISPLACED NORTHWEST OF THE DEEP CONVECTION. AN 110849Z
TRMM IMAGE SHOWED THE BULK OF THE DEEP CONVECTION OVER THE SOUTHERN
SEMI-CIRCLE AND SUPPORTED THE CURRENT POSITION AND MOTION. TC 23S
IS TRACKING SOUTHWARD ALONG THE WESTERN PERIPHERY OF THE LOW- TO
MID-LEVEL SUBTROPICAL RIDGE OVER COOLER SST (25-26C) AND VERY LOW
OCEAN HEAT CONTENT. THE SYSTEM IS FORECAST TO TRACK GENERALLY SOUTH-
WARD INTO A STRONG VERTICAL WIND SHEAR ENVIRONMENT AND WILL INTERACT
WEAKLY WITH A MIDLATITUDE TROUGH THROUGH TAU 36. TC 23S IS EXPECTED
TO CONTINUE TO WEAKEN AND WILL LIKELY DISSIPATE OVER WATER PRIOR
TO COMPLETING EXTRA-TROPICAL TRANSITION AFTER TAU 48. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 111200Z IS 28 FEET. NEXT WARNINGS AT
120300Z AND 121500Z. REFER TO TROPICAL CYCLONE 22S (JOKWE) WARN-

REMARKS:
120300Z POSITION NEAR 25.9S 79.4E.
TROPICAL CYCLONE (TC) 23S (KAMBA) LOCATED APPROXIMATELY 1140 NM
SOUTH-SOUTHEAST OF DIEGO GARCIA, HAS TRACKED SOUTHEASTWARD AT 10
KNOTS OVER THE PAST 06 HOURS. THE SYSTEM HAS CRESTED THE AXIS OF
THE LOW- TO MID-LEVEL SUBTROPICAL RIDGE AND IS NOW BEGINNING TO
UNDERGO EXTRATROPICAL TRANSITION AS IT MOVES FURTHER INTO COOLER
WATER AND COMES UNDER THE INCREASING INFLUENCE OF THE MIDLATITUDE
TROUGH TO THE WEST. ANIMATED METSAT IMAGERY INDICATES THAT THE
MAJORITY OF THE CONVECTION ASSOCIATED WITH TC 23S IS NOW DETACHED
FROM THE LOW LEVEL CIRCULATION CENTER (LLCC). THE LLCC IS EXPECTED
TO CONTINUE TRACKING SOUTH-SOUTHEASTWARD BEFORE COMPLETING EXTRA-
TROPICAL TRANSITION NEAR TAU 12. 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. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 120000Z IS 18 FEET. REFER TO TROPICAL
CYCLONE 22S (JOKWE) WARNINGS (WTXS32 PGTW) FOR TWELVE-HOURLY UP-
Tropical cyclone tracks developed by Michael Bath using operational warnings and advisories.
