REMARKS:
090900Z POSITION NEAR 18.2S 59.5E.
TROPICAL CYCLONE 13S (GELENA), LOCATED APPROXIMATELY 157 NM
NORTH-NORTHEAST OF PORT LOUIS, MAURITIUS, HAS TRACKED EAST-
SOUTHEASTWARD AT 19 KNOTS OVER THE PAST SIX HOURS. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY (MSI) SHOWS ROBUST DEEP CONVECTION
SURROUNDING A SMALL EYE. THE INITIAL POSITION IS BASED ON THE EYE
WITH HIGH CONFIDENCE. THE INITIAL INTENSITY IS ASSESSED AT 115 KNOTS
BASED ON MULTIAGENCY DVORAK CURRENT INTENSITY ESTIMATES OF T6.0 (115
KTS). TC 13S IS TAPPING INTO A MIDLATITUDE TROUGH TO ITS SOUTH AND
STRONG POLEWARD OUTFLOW, LOW VERTICAL WIND SHEAR, AND FAVORABLE SST
VALUES (29-30C) ARE FUELING CONTINUED INTENSIFICATION, WITH AN
EXPECTED PEAK AT 130 KTS AT TAU 12. TC 13S IS FORECAST TO TRACK EAST-
SOUTHEASTWARD TO EASTWARD THROUGH THE FORECAST PERIOD AS IT TRACKS
ALONG THE SOUTHERN PERIPHERY OF A NEAR-EQUATORIAL RIDGE. NUMERICAL
MODEL GUIDANCE REMAINS IN TIGHT AGREEMENT THROUGH TAU 72, BUT
UNCERTAINTY INCREASES SOMEWHAT AFTERWARDS IN ALONG-TRACK SPEED AND
NORTH-SOUTH SPREAD AS THE MIDLATITUDE TROUGH LEAVES TC 13S BEHIND.
AFTER TAU 72, ECMWF IS THE NORTHERN OUTLIER, WHILE NAVGEM AND GFS
BRING THE TRACK SOUTH OF THE MULTI-MODEL CONSENSUS; HOWEVER, ALL
MODELS AGREE ON A DUE EASTWARD TRACK AND SPREAD AT TAU 120 IS ONLY
150 NM. TC 13S IS EXPECTED TO WEAKEN STEADILY AFTER TAU 12 DUE TO
INCREASING WESTERLY VERTICAL WIND SHEAR AND UPPER-LEVEL CONVERGENCE
ASSOCIATED WITH THE SUBTROPICAL WESTERLIES. MESOSCALE MODEL
INTENSITY GUIDANCE HAS BACKED OFF IN THE NEAR TERM BUT STILL SHOWS
SLIGHT INTENSIFICATION THROUGH TAU 12. AFTERWARD, COAMPS-NAVGEM AND
HWRF MAINTAIN SYSTEM INTENSITY ABOVE 65 KTS THROUGHOUT THE FORECAST
PERIOD, ALTHOUGH VWS WILL REMAIN HIGH, DIVERGENCE ALOFT WILL BE
LIMITED BY UPPER-LEVEL SUBTROPICAL WESTERLIES, AND THE SYSTEM WILL
BE TRACKING INTO DRIER AIR. THE JTWC FORECAST FAVORS A WEAKENING AND
DISSIPATION SCENARIO DUE TO THE PERSISTENT MARGINAL TO UNFAVORABLE
ENVIRONMENT. OVERALL, THERE IS HIGH CONFIDENCE IN THE JTWC FORECAST
TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 090600Z IS 37 FEET. NEXT
WARNINGS AT 091500Z, 092100Z, 100300Z AND 100900Z.

2.C ADDITIONAL INFORMATION:
T=6.0+, CI=6.0+
EXTREMELY DANGEROUS CYCLONE GELENA HEADING TOWARDS RODRIGUES !
OVER THE PAST 6 HOURS, THE EYE PATTERN OF GELENA HAS CONTINUED TO
IMPROVE WITH A WARMING EYE AND COLDER CLOUD TOPS. THE INITIAL
INTENSITY IS RAISED AT 105 KT BASED ON LATEST DVORAK ANALYSIS.
SHORTLY BEFORE 06 UTC, THE RAW DT NUMBERS ARE NOW AT 6.5.
GELENA IS NOW ACCELERATING EAST-SOUTH-EASTWARDS AND GELENA IS STILL
EXPECTED TO RACE ON THIS TRACK UNTIL TOMORROW MORNING BEFORE A
GRADUAL DECREASE IN FORWARD MOTION. THE DEEP UPPER-TO-MID LEVELS
TROUGH LOCATED SOUTH OF THE MASCARENES ALONG WITH A STRENGTHENING
NEAR EQUATORIAL RIDGE IN THE NORTH-EAST ARE STILL STEERING THE
CYCLONE. THESE TWO SYNOPTIC FEATURES ARE FUNNELING THE TRACK AND
PROVIDE GOOD CONFIDENCE FOR THE NEXT TWO DAYS. FROM MONDAY THERE IS A
LOT MORE SPREAD IN THE GUIDANCE IN RELATIONSHIP WITH THE RATE OF
WEAKENING. THE CURRENT TRACK LIES MORE CLOSER TO THE GFS SOLUTION AT
THE INITIAL STAGE AND THEN IS CLOSE TO THE MULTI-ENSEMBLE LATER IN
THE FORECAST PERIOD.
THE CURRENT RAPID MOTION OF GELENA ALLOW IT TO ESCAPE THE HARMFUL
EFFECTS OF OF AN INCREASE OF THE SHEAR AT PRESENT TIME. GIVEN THE
CURRENT TREND, SOME ADDITIONAL STRENGTHENING IS LIKELY TODAY BEFORE A
WEAKENING TREND THAT SHOULD START LATER TONIGHT AND TOMORROW.
ON THIS TRACK, GELENA IS EXPECTED TO PASS VERY CLOSE OR OVER
RODRIGUES ISLANDS LATER TONIGHT OR TOMORROW MORNING. THIS IS A VERY
SERIOUS SITUATION AND THE INHABITANTS OF RODRIGUES ARE INVITED TO
CLOSELY MONITOR THE PROGRESS OF GELENA THROUGH THE NEXT WARNINGS AND
PRODUCTS FROM MMS. DYNAMICAL FETCH SHOULD TRIGGER A SIGNIFICANT SWELL
EVENT ALONG WITH ANOMALOUS SEA LEVEL RISING THAT COULD REACH 2 METERS
OVER SOME EXPOSED AREAS.=

LE SERVICE METEOROLOGIQUE DE MAURICE A RELEVE DES RAFALES MAXIMUM
DE 165KM/H ET UNE PRESSION ATMOSPHERIQUE MINIMALE DE 993 HPA SUR LA
STATION DE POINTE CANON A L'ILE RODRIGUES. A 0200Z, LA BOUEE OMM NUM
5601527 A RELEVE UNE PRESSION DE 981HPA A ENVIRON 22MN DU CENTRE DE
GELENA.
AU COURS DES 6 DERNIERES HEURES, LA STRUCTURE EN OEIL N'EST PAS
REAPPARUE SUR LES IMAGES IR, SEUL UN POINT CHAUD EST VISIBLE DE FACON
INTERMITTENTE. CEPENDANT, UN OEIL DECHIQUETE EST ENCORE PRESENT SUR
L'IMAGERIE VISIBLE. L'IMAGE MICRO-ONDE 89GHZ GMI DE 0106Z MONTRE UN
ANNEAU DE CONVECTION CENTRAL OUVERT DANS LE QUADRANT NORD-OUEST ET
UNE SECONDE BANDE S'ENROULANT AUTOUR DU COEUR PAR L'OUEST. CELA
SEMBLE SUGGERER QU'UN CYCLE DE REMPLACEMENT DU MUR DE L'OEIL A
DEBUTE MAIS QUE LE CISAILLEMENT DE SECTEUR NORD-OUEST L'A
POSSIBLEMENT INTERROMPU. POUR TENIR COMPTE DE L'AFFAIBLISSEMENT LIE A
CE DEBUT D'ERC, LE CI DE DVORAK N'A ETE GARDE QUE DE .5 AU DESSUS DU T
FINAL.
LE DEPLACEMENT DE GELENA RESTE PILOTE PAR LE PROFOND TALWEG DE HAUTE
A MOYENNE TROPO SITUE AU SUD DES MASCAREIGNES, ACCOMPAGNE D'UNE
DORSALE PROCHE EQUATORIALE AU NORD-EST. DEMAIN, AVEC
L'AFFAIBLISSEMENT DU TALWEG, GELENA DEVRAIT RALENTIR PROGRESSIVEMENT.
A PARTIR DE LUNDI SOIR, LE SYSTEME EST PREVU EVOLUER A L'ARRIERE DU
TALWEG D'ALTITUDE DANS UN FLUX D'OUEST ZONAL. LA TRAJECTOIRE DEVRAIT
ALORS SE REDRESSER VERS L'EST VOIRE MÊME TEMPORAIREMENT VERS
L'EST-NORD-EST AU COURS DE LA JOURNEE DE MARDI. LA DISPERSION DES
MODELES DETERMINISTES ET DE L'EPS MONTRENT UNE AUGMENTATION DE
L'INCERTITUDE A PARTIR DE LUNDI SOIR, UNE FOIS LE VIRAGE VERS L'OUEST
EFFECTUE.
DIMANCHE ET LUNDI, AVEC LE RALENTISSEMENT PREVU DE GELENA, LES EFFETS
DU CISAILLEMENT DEVRAIENT ETRE PLUS MARQUÉS ET DEVRAIENT CONDUIRE A
UN AFFAIBLISSEMENT. MAIS LE SYSTEME POURRAIT ENCORE TIRER PARTIE DE LA
BONNE DIVERGENCE D'ALTITUDE POUR CONSERVER UNE INTENSITE SIGNIFICATIVE
JUSQU'A LUNDI SOIR. A PARTIR DE MARDI, A L'ARRIÈRE DU TALWEG D'ALTITUDE, LA
DIVERGENCE D'ALTITUDE DIMINUE ET LE SYSTEME DEVRAIT ALORS S'AFFAIBLIR
PLUS RAPIDEMENT. EN ALTITUDE, LES VENTS D'OUEST DE MOYENNE/HAUTE
TROPOSPHERE AU NORD DU JET SUBTROPICAL NE LAISSENT PAS DE POSSIBILITE DE
REINTENSIFICATION.
