SUBJ/TROPICAL CYCLONE FORMATION ALERT 080151Z NOV 04//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
165 NM EITHER SIDE OF A LINE FROM 8.9S7 80.8E6 TO 13.0S4 77.2E6
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 072330Z5 INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 9.3S2 80.3E1. THE SYSTEM IS MOVING SOUTHWESTWARD AT 13
KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 7.8S5
81.9E8, IS NOW LOCATED NEAR 9.3S2 80.3E1, APPROXIMATELY 480 NM
EAST OF DIEGO GARCIA. ANIMATED WATER VAPOR SATELLITE IMAGERY
REVEALS THAT DEEP CONVECTION CONTINUES TO PERSIST OVER A
DEVELOPING LOW LEVEL CIRCULATION CENTER. UPPER LEVEL ANALYSIS
INDICATES MODERATE DIFFLUENCE ALOFT IN THE POLEWARD DIRECTION AND
WEAK TO MODERATE VERTICAL WIND SHEAR IN A LOCATION JUST
EQUATORWARD OF THE SUBTROPICAL RIDGE AXIS. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 30 KNOTS. MINIMUM SEA LEVEL PRESSURE
IS ESTIMATED TO BE 1004 MB. DUE TO PERISTENT CONVECTION AND IMPROVED
ORGANIZATION, 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
090200Z1.//

REMARKS:
080900Z7 POSITION NEAR 10.0S1 78.9E4.
TROPICAL CYCLONE (TC) 03S, LOCATED APPROXIMATELY 420 NM EAST-
SOUTHEAST OF DIEGO GARCIA, HAS TRACKED WEST-SOUTHWESTWARD AT
12 KNOTS OVER THE PAST 06 HOURS. THE WARNING POSITION IS BASED
ON 080530Z6 MULTISPECTRAL SATELLITE IMAGERY. THE WARNING INTEN-
SITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 30 AND
35 KNOTS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND A RECENT
QUIKSCAT PASS REVEAL THAT THE CONVECTION ASSOCIATED WITH THE
DEVELOPING LOW LEVEL CIRCULATION CENTER (LLCC) IS BECOMING MORE
ORGANIZED. TC 03S IS FORECAST TO TRACK WEST-SOUTHWESTWARD UNDER
THE STEERING INFLUENCE OF AN ANTICYCLONE ANCHORED TO THE SOUTH
OF THE SYSTEM. TC 03S IS FORECAST TO INTENSIFY SLOWLY FOR THE
FIRST 36 HOURS IN AN ENVIRONMENT OF LOW TO MODERATE VERTICAL WIND
SHEAR AND GOOD POLEWARD OUTFLOW. AFTER TAU 36, INTENSIFICATION
WILL BE HINDERED BY HIGHER VERTICAL WIND SHEAR. MAXIMUM SIGNIF-
ICANT WAVE HEIGHT AT 080600Z4 IS 10 FEET. THIS WARNING SUPERSEDES
AND CANCELS REF A, NAVPACMETOCCEN 080151ZNOV2004 TROPICAL CYCLONE

REMARKS:
090300Z2 POSITION NEAR 11.1S3 77.0E4.
THE WARNING HAS BEEN AMENDED DUE TO A RAPID INTENSIFYING TREND BASED
ON RECENT ENHANCED INFRARED SATELLITE IMAGERY. TROPICAL CYCLONE (TC)
03S (AROLA), LOCATED APPROXIMATELY 365 NM SOUTHEAST OF DIEGO GARCIA,
HAS TRACKED WEST-SOUTHWESTWARD AT 08 KNOTS OVER THE PAST 06 HOURS.
THE WARNING POSITION IS BASED ON 082330Z6 ENHANCED INFRARED SATELLITE
IMAGERY. THE WARNING INTENSITY IS BASED ON SATELLITE CURRENT
INTENSITY ESTIMATES OF 65 AND 77 KNOTS. ANIMATED ENHANCED WATER VAPOR
AND INFRARED IMAGERY REVEALS A VERY STRONG POLEWARD OUTFLOW CHANNEL.
DEEP CONVECTION AROUND THE LOW-LEVEL CIRCULATION CENTER HAS PERSISTED
AND INCREASED DURING THE PAST 06 HOURS. SURFACE INFLOW CONTINUES TO
BE STRONG WITH FEEDER BANDS STRETCHING OVER 300 NM EQUATORWARD OF
THE SYSTEM. THE AVAILABLE DYNAMIC AIDS CONSISTING OF TCLAPS, UKMO,
AND WBAR ARE IN POOR AGREEMENT. WBAR RESOLVES A SOLUTION WHICH TRACKS
TC 03S POLEWARD WHILE TCLAPS TRACKS THE SYSTEM EQUATORWARD. UKMO IS
MORE REPRESENTATIVE OF THE SYNOPTIC SCALE FLOW, HOWEVER THIS MODEL AND
TCLAPS DEPICT A STRONG SUBTROPICAL STEERING RIDGE TO THE SOUTH. GIVEN
THE RAPID INTENSIFICATION OF TC 03S AND THE CLOSE PROXIMITY TO AN
AREA OF INCREASED VERTICAL WIND SHEAR TO THE SOUTH, THE INTENSITY IS
EXPECTED TO STRENGTHEN SLIGHTLY, THEN MAINTAIN THROUGH THE MAJORITY
OF THE FORECAST PERIOD. AS TC 03S MOVES INTO AN ENVIRONMENT OF
INCREASED SHEAR, THE INTENSITY WILL BEGIN TO WEAKEN. ADDITIONALLY,
THE STRENGTH OF THE POLEWARD OUTFLOW CHANNEL SHOULD OFFSET ANY RAPID
WEAKENING DUE TO SHEAR. AFTER TAU 48, THE SYSTEM IS EXPECTED TO MOVE
OVER COOLER SEA SURFACE TEMPERATURES AND CONTINUE TO WEAKEN. THIS
FORECAST IS BASED ON A CONSENSUS OF ALL AVAILABLE DYNAMIC AIDS.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 090000Z9 IS 10 FEET. NEXT

092100Z2 POSITION NEAR 11.0S2 74.9E0.
TROPICAL CYCLONE (TC) 03S (AROLA), LOCATED APPROXIMATELY 275 NM
SOUTHEAST OF DIEGO GARCIA, HAS TRACKED WESTWARD AT 07 KNOTS OVER THE
PAST 06 HOURS. THE WARNING POSITION IS BASED ON 091730Z0 ENHANCED
INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON
SATELLITE CURRENT INTENSITY ESTIMATES OF 65 KNOTS FROM ALL FIXING
AGENCIES. ANIMATED ENHANCED INFRARED IMAGERY REVEALS A DECREASE IN
OVERALL CONVECTION, AND RECENT MICROWAVE IMAGERY SHOWS A PARTIALLY
EXPOSED LOW-LEVEL CIRCULATION WITH THE STRONGEST CONVECTION SITUATED
IN THE NORTHWEST QUADRANT. ANIMATED ENHANCED WATER VAPOR IMAGERY
ALSO REVEALS A STRONG POLEWARD OUTFLOW CHANNEL, BUT THERE IS VERY
LITTLE RADIAL OUTFLOW IN OTHER QUADRANTS. THE AVAILABLE DYNAMIC AIDS
CONSISTING OF TCLAPS, GFDN, UKMO, MM5, AND WBAR ARE IN POOR TO FAIR
AGREEMENT. MM5 AND WBAR RESOLVE A SOLUTION WHICH TRACKS TC 03S POLE-
WARD AFTER TAU 12 WHILE GFDN AND UKMO MAINTAIN A GENERAL WESTWARD
TRACK. TCLAPS RESOLVES A SOLUTION WHICH TRACKS THE SYSTEM EQUATOR-
WARD. GIVEN THE STRENGTH OF THE SUBTROPICAL RIDGE SITUATED SOUTH
OF THE SYSTEM, THE TRACK SHOULD REMAIN WESTWARD WITH A GRADUAL GAIN
IN LATITUDE AFTER TAU 24. THE INTENSITY WILL SLOWLY DECREASE THROUGH
THE FORECAST PERIOD AS TC 03S MOVES ALONG A REGION OF LOW TO
MODERATE VERTICAL WIND SHEAR. THIS FORECAST IS BASED ON A CONSENSUS
OF ALL AVAILABLE DYNAMIC AIDS WITH LESS EMPHASIS ON MM5 AND WBAR.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 091800Z8 IS 18 FEET. NEXT WARNINGS
AT 100900Z0 AND 102100Z4.//

REMARKS:
100900Z0 POSITION NEAR 10.5S6 74.8E9.
TROPICAL CYCLONE (TC) 03S (AROLA), LOCATED APPROXIMATELY 250 NM
SOUTHEAST OF DIEGO GARCIA, HAS TRACKED NORTH-NORTHWESTWARD AT 07
KNOTS OVER THE PAST 06 HOURS. THE WARNING POSITION IS BASED ON
1005330Z2 MULTISPECTRAL SATELLITE IMAGERY. THE WARNING INTENSITY
IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 55, 65 AND
77 KNOTS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY REVEALS A
DECREASE IN OVERALL CONVECTION AND A PARTIALLY EXPOSED LOW-LEVEL
CIRCULATION (LLCC) IN THE NORTHWEST QUADRANT. THE STRONGEST
CONVECTION IS LOCATED ALONG THE SOUTHERN PORTION OF THE LLCC WITH
A BAND OF CONVECTION EXTENDING NORTHEASTWARD. RECENT CIMSS DATA
INDICATES A GOOD POLEWARD OUTFLOW CHANNEL, BUT ALSO INDICATES TC
03S IS IN AN AREA OF MODERATE VERTICAL WIND SHEAR THAT IS HAMPERING
DEVELOPMENT. THE AVAILABLE DYNAMIC AIDS CONSISTING OF NOGAPS, NCEP
GFS, TLAPS, MM5, AND WBAR ARE IN POOR AGREEMENT. BASED ON THE
STORMS TRACK NORTHWESTWARD OVER THE PAST 12 HOURS, THE FORECASTED
TRACK HAS BEEN DEVIATED FROM THE CONW TO MAINTAIN A WESTWARD TRACK.
AN ALTERNATE SCENARIO IS FOR TC 03S TO CONTINUE TRACKING
NORTHWESTWARD BEFORE MAKING A LOOP AND THEN CONTINUING TO TRACK
WESTWARD ALONG THE SOUTHERN PERIPHERY OF THE SUBTROPICAL RIDGE.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 100600Z7 IS 22 FEET. NEXT

TROPICAL CYCLONE (TC) 03S (AROLA), LOCATED APPROXIMATELY 300 NM
SOUTH-SOUTHEAST OF DIEGO GARCIA, HAS TRACKED SOUTHWESTWARD AT 05
KNOTS OVER THE PAST 06 HOURS. THE WARNING POSITION IS BASED ON
111730Z3 ENHANCED INFRARED SATELLITE IMAGERY. THE WARNING
INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF
35, 45 AND 55 KNOTS. ANIMATED SATELLITE IMAGERY INDICATES THAT
THE STRONGEST CONVECTION REMAINS POLEWARD OF A WELL-DEVELOPED
LOW-LEVEL CIRCULATION CENTER. TC 03S IS FORECAST TO CONTINUE TO
TRACK SOUTHWESTWARD ALONG THE PERIPHERY OF AN ANTICYCLONE
CENTERED TO THE SOUTHEAST. THE SYSTEM IS FORECAST TO WEAKEN
THROUGH TAU 48 AS IT ENCOUNTERS AN ENVIRONMENT OF INCREASED
VERTICAL WIND SHEAR. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 111800Z1
IS 16 FEET. NEXT WARNINGS AT 120900Z2 AND 122100Z6.//

CONTINUE TO DRIFT ALONG A SOUTHWEST TRACK AROUND THE NORTHWEST
PERIPHERY OF THE STEERING RIDGE FOR THE NEXT 24 HOURS, THEN IT WILL
BECOME EMBEDDED IN THE MIDLATITUDE WESTERLIES. THE SYSTEM IS FORECAST
TO WEAKEN AND DISSIPATE OVER WATER AS IT ENCOUNTERS A REGION OF
MODERATE TO HIGH VERTICAL WIND SHEAR. MAXIMUM SIGNIFICANT WAVE HEIGHT
AT 121800Z2 IS 14 FEET. NEXT WARNINGS AT 130900Z3 AND 132100Z7.//
