MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/TROPICAL CYCLONE FORMATION ALERT//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
120 NM EITHER SIDE OF A LINE FROM 20.7S 41.2E TO 24.9S 43.9E
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 27 TO 32 KNOTS. METSAT
IMAGERY AT 060600Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 21.4S 41.6E. THE SYSTEM IS MOVING EAST-SOUTHEASTWARD AT 05
KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 20.0S
38.9E, IS NOW LOCATED NEAR 21.4S 41.6E, APPROXIMATELY 340 NM WEST-
SOUTHWEST OF ANTANANARIVO, MADAGASCAR. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY (MSI) CONTINUES TO SHOW A MORE DEVELOPED
CIRCULATION AND BETTER CONVECTION, AS WELL AS SOME POSSIBLE LIGHT
BANDING, ASSOCIATED WITH THIS SYSTEM. THE LOW-LEVEL CIRCULATION
CENTER (LLCC) IS CONCEALED BY THE HEAVY CONVECTIVE SIGNATURE ON THE
EASTERN SIDE OF THE SYSTEM AS SEEN IN THE 060429Z SSMIS, MID-LEVEL
TURNING IS CLEARLY EVIDENT IN THE MSI. ADDITIONALLY, AN EARLIER
060228Z ISS RSCAT SHOWS THE MAJORITY OF INTENSE (25 TO 30 KTS) WINDS
ARE LOCATED IN THE NORTHEASTERN QUADRANT WITH FAIRLY WEAK FLOW (10
TO 15 KTS) ALONG THE SOUTHWESTERN SIDE. THERE IS MODERATE (20 KTS)
SOUTHWESTERLY VERTICAL WIND SHEAR WHICH IS OFFSET BY GOOD DIVERGENT
OUTFLOW AND GOOD SSTS, LEADING TO AN OVERALL CONDUCIVE ENVIRONMENT
FOR  FURTHER DEVELOPMENT. NUMERIC DYNAMIC MODELS ARE IN GOOD
AGREEMENT OF A TROPICAL CYCLONE STRENGTH SYSTEM DEVELOPING FROM THIS
SYSTEM WITHIN THE NEXT 24 HOURS. FOR THE AFOREMENTIONED REASONS, 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
070900Z.//

REMARKS:
062100Z POSITION NEAR 23.1S 43.0E.
TROPICAL CYCLONE (TC) 11S (FUNDI), LOCATED APPROXIMATELY 315 NM
SOUTHWEST OF ANTANANARIVO, MADAGASCAR HAS TRACKED
SOUTH-SOUTHEASTWARD AT 09 KNOTS OVER THE PAST SIX HOURS. ANIMATED
ENHANCED INFRARED (EIR) SATELLITE IMAGERY SHOWS WELL DEFINED
CONVECTIVE BANDING WRAPPING INTO THE LOW LEVEL CIRCULATION CENTER
(LLCC). A 061701Z SSMIS MICROWAVE IMAGE REVEALS THAT THE BANDING HAS
EXPANDED TO THE SOUTHERN QUADRANT OF THE SYSTEM AND HAS STARTED TO
WRAP AROUND THE CENTER. UPPER LEVEL ANALYSIS INDICATES THAT TC FUNDI
IS IN A MARGINALLY FAVORABLE ENVIRONMENT, LOCATED JUST SOUTH OF THE
RIDGE AXIS IN AN AREA OF STRONG DIVERGENCE WITH GOOD EQUATORWARD
OUTFLOW. HOWEVER MODERATE (20 KNOTS) VERTICAL WIND SHEAR (VWS) AND
SUBSIDENCE FROM A SHORT WAVE TROUGH TO THE WEST WILL LIMIT OVERALL
INTENSIFICATION. THE INITIAL POSITION IS BASED ON THE EIR LOOP AND
MICROWAVE IMAGERY WITH GOOD CONFIDENCE. THE INITIAL INTENSITY OF 35
KNOTS IS BASED ON THE HIGH END OF AGENCY DVORAK INTENSITY ESTIMATES
OF 30 TO 35 KNOTS. TC 11S IS TRACKING UNDER THE STEERING INFLUENCE
OF A LOW- TO MID-LEVEL SUB-TROPICAL RIDGE (STR) TO THE EAST. AS TC
FUNDI TRACKS POLEWARD THROUGH TAU 48, ENVIRONMENTAL CONDITIONS WILL
REMAIN MODERATELY FAVORABLE ALLOWING THE SYSTEM TO REACH A PEAK
INTENSITY OF 55 KNOTS. BEYOND TAU 48 THE CYCLONE WILL TURN TO THE
SOUTHWEST AS THE STR BUILDS IN TO THE SOUTH. AT THIS POINT, TC FUNDI
WILL BEGIN ITS WEAKENING TREND AS IT ENCOUNTERS INCREASED VWS AND
COOLER SSTS (BELOW 26C). BY TAU 72, TC 11S WILL START TO ROUND THE
STR AXIS AND BEGIN EXTRA-TROPICAL TRANSITION (ETT). EXPECT THE
SYSTEM TO COMPLETE ETT BY THE END OF THE FORECAST PERIOD. AVAILABLE
MODEL GUIDANCE IS IN FAIR AGREEMENT THROUGH THE FORECAST PERIOD
LENDING TO GOOD CONFIDENCE IN THE JTWC FORECAST. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 061800Z IS 10 FEET. NEXT WARNINGS AT 070900Z AND

REMARKS:
070900Z POSITION NEAR 23.9S 43.7E.
TROPICAL CYCLONE (TC) 11S (FUNDI), LOCATED APPROXIMATELY 330 NM
SOUTHWEST OF ANTANANARIVO, MADAGASCAR, HAS TRACKED SOUTHEASTWARD AT
05 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY (MSI) DEPICTS TIGHTLY-CURVED BANDING WRAPPING INTO THE LOW
LEVEL CIRCULATION CENTER (LLCC) STRADDLING EASTERN COAST OF
MADAGASCAR. A 070417Z SSMIS MICROWAVE IMAGE REVEALS THE BULK OF THE
CONVECTIVE BANDING OVER THE NORTHEASTERN QUADRANT WRAPPING INTO THE
LLCC. UPPER-LEVEL ANALYSIS INDICATES THAT TC 11S IS LOCATED IN AN
AREA OF MODERATE (10 TO 20 KNOT) VERTICAL WIND SHEAR OFFSET BY GOOD
POLEWARD OUTFLOW. THE INITIAL POSITION IS BASED ON THE MSI AND
SATELLITE FIXES FROM PGTW, KNES AND FMEE WITH GOOD CONFIDENCE.
DVORAK VALUES ARE UNAVAILABLE DUE TO THE LLCC PROXIMITY TO LAND;
THEREFORE, THE INITIAL INTENSITY REMAINS AT 35 KNOTS BASED ON THE
OVERALL STRUCTURE AS IT INTERACTS WITH THE COASTLINE AND SATELLITE
CONSENSUS (SATCON) OF 32 KNOTS. TC FUNDI IS TRACKING UNDER THE
STEERING INFLUENCE OF A LOW- TO MID-LEVEL SUB-TROPICAL RIDGE (STR)
TO THE EAST.  MARGINALLY FAVORABLE CONDITIONS ARE EXPECTED TO
PERSIST ALLOWING TC 11S TO SLOWLY INTENSIFY REACHING A PEAK
INTENSITY OF 50 KNOTS OVER THE NEXT 24 HOURS.  AFTER TAU 24, THE
CYCLONE WILL TURN SOUTHWESTWARD AS THE STR BUILDS IN TO THE SOUTH.
CONCURRENTLY,  TC 11S WILL BEGIN ITS WEAKENING TREND AS IT
ENCOUNTERS INCREASED VWS AND  COOLER SEA SURFACE TEMPERATURES. BY
TAU 72, TC 11S WILL START TO ROUND THE STR AXIS AND BEGIN EXTRA-
TROPICAL TRANSITION (ETT).  TC 11S IS FORECAST TO COMPLETE ETT BY
THE END OF THE FORECAST PERIOD. AVAILABLE MODEL GUIDANCE REMAINS IN

SOUTH-SOUTHWEST OF ANTANANARIVO, MADAGASCAR, HAS TRACKED
SOUTH-SOUTHEASTWARD AT 09 KNOTS OVER THE PAST SIX HOURS. ANIMATED
ENHANCED INFRARED SATELLITE IMAGERY REVEALS THAT TC FUNDI HAS MOVED

TC 11S IS LOCATED IN AN AREA OF MODERATE WESTERLY (10 TO 20 KNOT)
VERTICAL WIND SHEAR (VWS) WHICH IS BEING OFFSET BY GOOD POLEWARD AND
EQUATORWARD OUTFLOW AS EVIDENT ON WATER VAPOR IMAGERY. THE INITIAL
POSITION IS BASED ON THE AFOREMENTIONED MICROWAVE IMAGE AND MULTI-
AGENCY FIXES WITH GOOD CONFIDENCE. THE INITIAL INTENSITY OF 35 KNOTS
IS BASED ON CONCURRING AGENCY CURRENT INTENSITY ESTIMATES OF 35
KNOTS. TC 11S IS STILL TRACKING UNDER THE INFLUENCE OF A LOW- TO MID-

REMARKS:
080900Z POSITION NEAR 28.7S 43.7E.
TROPICAL CYCLONE 11S (FUNDI), LOCATED APPROXIMATELY 570 NM SOUTH-
SOUTHWEST OF ANTANANARIVO, MADAGASCAR, HAS TRACKED SOUTHWARD AT 13
KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY (MSI) AND 080650Z METOP-B MICROWAVE IMAGE DEPICT THE BULK OF
THE DEEP CONVECTION HAS DISPLACED SOUTHWEST OF THE LOW-LEVEL
CIRCULATION CENTER. UPPER-LEVEL ANALYSIS INDICATES TC 11S IS NOW
LOCATED IN AN AREA OF MODERATE TO HIGH (20 TO 30 KNOT) VERTICAL WIND
SHEAR (VWS) WHICH IS BEING OFFSET BY EXCELLENT POLEWARD OUTFLOW. THE
CURRENT POSITION IS BASED ON THE MSI AND AFOREMENTIONED MICROWAVE
IMAGE WITH GOOD CONFIDENCE. THE INITIAL INTENSITY OF 40 KNOTS IS
BASED ON THE CURRENT STRUCTURE AND IS HEDGED SLIGHTLY HIGHER THAN
DVORAK INTENSITY ESTIMATE FROM PGTW. TC 11S IS TRACKING UNDER THE
STEERING INFLUENCE OF A LOW- TO MID-LEVEL SUB-TROPICAL RIDGE TO THE
EAST. OVER THE NEXT 24 HOURS, TC FUNDI WILL FURTHER TRACK INTO AN
UNFAVORABLE AREA OF INCREASING VWS AND COOLER SEA SURFACE
TEMPERATURES. THIS COMBINED EFFECT WILL WEAKEN THE SYSTEM LEADING TO
ITS DISSIPATION BY THE END OF THE FORECAST PERIOD, OR POSSIBLY
SOONER. AVAILABLE MODEL GUIDANCE CONTINUES TO BE IN GOOD AGREEMENT
LENDING TO HIGH CONFIDENCE IN JTWC TRACK FORECAST. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 080600Z IS 12 FEET. NEXT WARNING AT
082100Z.//

REMARKS:
082100Z POSITION NEAR 33.4S 43.8E.
TROPICAL CYCLONE (TC) 11S (FUNDI), LOCATED APPROXIMATELY 840 NM SOUTH
OF ANTANANARIVO, MADAGASCAR, HAS TRACKED SOUTHWARD AT 25 KNOTS OVER
THE PAST SIX HOURS. ENHANCED INFRARED SATELLITE IMAGERY DEPICTS AN
ELONGATING AND WEAKENING CONVECTIVE STRUCTURE WHICH IS LEAVING THE
LOW LEVEL CIRCULATION CENTER (LLCC) PARTIALLY EXPOSED. TC 11S HAS
MOVED INTO AN AREA OF STRONG (30 TO 40 KNOT) VERTICAL WIND SHEAR AND
SEA SURFACE TEMPERATURES BELOW 25C. IN ADDITION, DRY AIR IS WRAPPING
INTO THE LLCC WHICH IS EVIDENT IN THE 081634Z SSMIS COLOR COMPOSITE
MICROWAVE IMAGE. THESE ENVIRONMENTAL CONDITIONS WILL ONLY AGGRAVATE
AND CONTINUE TO RAPIDLY DETERIORATE THE SYSTEM LEADING TO COMPLETE
DISSIPATION WITHIN 12 HOURS. THIS IS THE FINAL WARNING ON THIS
SYSTEM BY THE JOINT TYPHOON WRNCEN PEARL HARBOR HI. THE SYSTEM WILL
BE CLOSELY MONITORED FOR SIGNS OF REGENERATION. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 081800Z IS 10 FEET.//
