JTWC 09z評級 Low

(1) AN AREA OF CONVECTION (INVEST 98S) HAS PERSISTED NEAR
10.0S 71.6E, APPROXIMATELY 166 NM SOUTH-SOUTHWEST OF DIEGO. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY AND A 030508Z PARTIAL AMSU 89GHZ
IMAGE DEPICTS A DISORGANIZED LOW LEVEL CIRCULATION CENTER (LLCC)
WITH MAJORITY OF THE CONVECTION LOCATED IN THE NORTHERN WESTERN
PERIPHERY. UPPER LEVEL ANALYSIS DEPICTS 98S LOCATED IN AN AREA WITH
MODERATE TO SEVERE (15-20 KNOTS) VERTICAL WIND SHEAR AND WEAK
OUTFLOW. SUPPORTIVE SEA SURFACE TEMPERATURES (30-32 CELSIUS) WILL
CONTINUE TO ENHANCE 98S OVER THE NEXT SEVERAL DAYS. GLOBAL MODELS
ARE IN GOOD AGREEMENT THAT 98S WILL DEVELOP AND TRACK TO THE
SOUTHEAST, BUT DO NOT AGREE ON THE INTENSIFICATION AND THE TIMING
THEREOF. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1007 MB.  
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS.
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1007 MB. THE
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS LOW.

JTWC 11Z評級提升至Medium，機構看好發展。

(1) THE AREA OF CONVECTION (INVEST 98S) PREVIOUSLY LOCATED
NEAR 10.5S 71.6E, IS NOW LOCATED NEAR 13.4S 69.2E, APPROXIMATELY 785
NM EAST-NORTHEAST OF MAURITIUS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY AND A 040850Z 89GHZ AMSR2 MICROWAVE IMAGE DEPICT A LARGE
CENTRALLY LOCATED MASS OF CONVECTION WITH SOME FRAGMENTARY BANDING
WRAPPING INTO THE PARTIALLY EXPOSED LOW LEVEL CIRCULATION CENTER.
THE UPPER LEVEL ENVIRONMENT IS OVERALL FAVORABLE, WITH STRONG
DIVERGENCE ALOFT DUE TO FORMATIVE DUAL CHANNEL OUTFLOW SLIGHTLY
OFFSET BY MODERATE (10-20KTS) VERTICAL WIND SHEAR. SEA SURFACE
TEMPERATURES REMAIN FAVORABLY WARM (28-30C) IN THIS REGION OF THE
SOUTHERN INDIAN OCEAN. GLOBAL MODELS ARE IN OVERALL AGREEMENT THAT
THE SYSTEM WILL CONTINUE TO CONSOLIDATE AND REACH 35 KNOTS WITHIN
THE NEXT 36-54 HOURS. JGSM IS DISSENTING, FAVORING DEVELOPMENT OF
INVEST 97S INSTEAD. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT
20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR
1007 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL
CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO MEDIUM.

2.C COMMENTAIRES:
LA CONVECTION ASSOCIEE A LA CIRCULATION DE BASSES COUCHES SUIVIE DEPUIS
PLUSIEURS JOURS S'EST MAINTENUE AU COURS DES DERNIERES 24H. LA DERNIERE
PASSE ASCAT DE 0448UTC PERMET D'ESTIMER DES VENT DE L'ORDRE DE 20KT, MAIS
SUR LES DERNIERES IMAGES MICRO-ONDES DE 0850UTC ET 1058UTC LA
CIRCULATION SEMBLE ENCORE MAL DEFINIE.
LA CONFIGURATION DES GRANDS CENTRES D'ACTION, QUE CE SOIT EN ALTITUDE
OU EN BASSES COUCHES, PERMET DE DEFINIR UNE BONNE CONFIANCE EN TERME
DE TRAJECTOIRE. APRES UNE ORIENTATION SUD-OUEST EN DEBUT DE VIE,
GLISSANT SUR LES HAUTS GEOPOTENTIELS POSITIONNES ACTUELLEMENT AU
CENTRE DU BASSIN, LE PROFOND TALWEG QUI CIRCULE AU SUD VA OUVRIR UN
CANAL D'EVACUATION A ECHEANCE DE 36H, EN DECALANT LES HAUTS
GEOPOTENTIELS SUR LA PARTIE EST DU BASSIN. CE CANAL VA PERMETTRE UNE
TRAJECTOIRE VERS LE SUD-EST BIEN DEFINIE A PARTIR DE MERCREDI.
L'INCERTITUDE SE PLACE PLUTOT EN TERME DE PREVISION D'INTENSITE DU A
L'INFLUENCE CONJOINTE AVEC UNE DEUXIEME CIRCULATION SE SITUANT AU
SUD-EST D'AGALEGA. LES MODELES NUMERIQUES SONT EN TOTAL DESACCORD
SUR L'EVOLUTION DE SES DEUX SYSTEMES : LE DEVELOPPEMENT DE L'UN ALLANT
A L'ENCONTRE DE L'AUTRE. LA PREVISION ACTUELLE DU CMRS PRIVILEGIE LE
DEVELOPPEMENT DU SYSTEME 08-20182019 AU DETRIMENT DE LA CIRCULATION AU
SUD-EST DE AGALEGA. ACTUELLEMENT SOUS UNE ZONE DE CISAILLEMENT FAIBLE
A MODERE, LA PERTURBATION TROPICALE VA VOIR SON INTENSITE AUGMENTER
PROGRESSIVEMENT. SANS CONTRAINTE OCEANIQUE, CE SONT LES CONDITIONS
ATMOSPHERIQUES QUI JOUENT : L'AUGMENTATION DU CISAILLEMENT LE LONG DE
LA TRAJECTOIRE DU SYSTEME ET UN ENVIRONNEMENT ASSEZ SEC DANS LA PARTIE
SUD VA TOUTEFOIS LIMITER CETTE INTENSIFICATION, LAISSANT LE SYSTEME
08-20182019 ATTEINDRE LE SEUIL DE CYCLONE QUE ASSEZ TARDIVEMENT, AVANT

1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
150 NM EITHER SIDE OF A LINE FROM 14.0S 67.7E TO 17.9S 64.2E
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 IMAGERY AT
042030Z INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 14.4S
67.1E. THE SYSTEM IS MOVING SOUTHWESTWARD AT 11 KNOTS.
2. REMARKS: THE AREA OF CONVECTION (INVEST 98S) PREVIOUSLY LOCATED
NEAR 13.7S 67.9E, IS NOW LOCATED NEAR 14.4S 67.1E, APPROXIMATELY 645
NM EAST-NORTHEAST OF MAURITIUS. ANIMATED ENHANCED INFRARED SATELLITE

SEMICIRCLE WRAPPING INTO A BROAD LOW LEVEL CIRCULATION CENTER. A
041722Z ASCAT IMAGE SHOWS A DEFINED CIRCULATION WITH 25 TO 30 KNOT
WINDS. THE UPPER LEVEL ENVIRONMENT IS FAVORABLE WITH STRONG
DIVERGENCE ALOFT DUE TO DUAL CHANNEL OUTFLOW AND LOW (10-15KTS)
VERTICAL WIND SHEAR. SEA SURFACE TEMPERATURES ARE FAVORABLE (28-
30C). GLOBAL MODELS ARE IN OVERALL AGREEMENT THAT THE SYSTEM WILL
TRACK WEST-SOUTHWESTWARD TO SOUTHWESTWARD OVER THE NEXT TWO DAYS
WITH STEADY INTENSIFICATION. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 25 TO 30 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED
TO BE NEAR 1000 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS HIGH.

2.C COMMENTAIRES:
T=CI=2.5-
AU COURS DES DERNIERES 6 HEURES, LA CONVECTION EST RESTEE TRES FORTE
DANS LE DEMI-CERCLE NORD TOUT EN RESTANT TRES FLUCTUANTE. DANS LE
DEMI-CERCLE SUD, LA CONVECTION SEMBLE TOUJOURS PERTURBEE PAR LA
PRESENCE D'AIR SEC. CEPENDANT, L'IMAGE MICRO-ONDE 37 GHZ SSMI DE 2207Z
MONTRE UNE CIRCULATION DE BASSES COUCHES DE MIEUX EN MIEUX DEFINI.
LA CONFIGURATION DES GRANDS CENTRES D'ACTION, QUE CE SOIT EN ALTITUDE
OU EN BASSES COUCHES, PERMET DE DEFINIR UNE BONNE CONFIANCE EN TERME
DE TRAJECTOIRE. LE SYSTEME EST PREVU SE DEPLACER VERS LE SUD-OUEST
PILOTE PAR LA DORSALE DE BASSE/MOYENNE TROPOSPHERE SITUEE DANS LE
SUD-EST DU SYSTEME. A PARTIR DE MERCREDI, LA DORSALE SE DECALE VERS
L'EST ET LAISSE PLACE A UN PROFOND TALWEG DES MOYENNES LATITUDES. LA
TRAJECTOIRE DU SYSTEME VA ALORS S'INCURVER VERS LE SUD PUIS A PARTIR DE
JEUDI VERS LE SUD-EST EN ACCELERANT.
SUR CETTE TRAJECTOIRE, LES CONDITIONS ENVIRONNEMENTALES SONT PLUTOT
FAVORABLES JUSQU'A JEUDI. L'ALIMENTATION DE BASSES COUCHES EST TRÈS
BONNE CÔTE EQUATORIALE ET DEVRAIT RESTER SUFFISANTE CÔTE POLAIRE
AVANT L'ARRIVÉE DU PROFOND TALWEG DE SURFACE. LES CONDITIONS
D'ALTITUDE SONT BONNES AVEC UNE TRÈS BONNE DIVERGENCE D'ALTITUDE A LA
FOIS CÔTE POLAIRE ET EQUATORIALE ET UN FAIBLE CISAILLEMENT VERTICAL DE
VENT. SEUL L'AIR SEC DE MOYENNE TROPOSPHERE ADVECTE PAR LA DORSALE DE
BASSES COUCHES PEUT RALENTIR L'INTENSIFICATION DU SYSTEME. A PARTIR DE
VENDREDI, LE CISAILLEMENT D'OUEST LIÉ A L'ARRIVÉE DU PROFOND TALWEG
D'ALTITUDE DEVRAIT DEVENIR MODERE A FORT ET AFFAIBLIR LE SYSTEME. A
PARTIR DE CE WEEK-END, EN INTERAGISSANT AVEC LE JET SUBTROPICAL, LE
SYSTEME DEVRAIT PERDRE SES CARACTERISTIQUES PUREMENT TROPICALES. LES
MODELES SONT GLOBALEMENT EN ACCORD AVEC CE SCENARIO.

Special Weather Bulletin
Info on the low pressure systems to the north northeast of Rodrigues and in the vicinity of Agalega
Issued at 1400 hours on Tuesday 05 February 2019.

1. The tropical disturbance located far to the southwest of Diego Garcia intensified into a tropical depression during last night. At 1000 hours this morning it was centered at about 550 km to the north northeast of Rodrigues. This system will move in a general southwesterly direction at a speed of about 15 km/h, while continuing to intensify and becoming a moderate tropical storm by this evening. It will then be named FUNANI. The tropical storm is expected to recurve towards the south-east as from Wednesday 06 February 2019. On this trajectory the centre of the storm will approach Rodrigues and is likely to pass at about 160 km to the East Northeast of Rodrigues on Wednesday 06 February around mid-night.
