2.B OTHER INFORMATIONS:
T=CI=2.5-
LOW LEVEL CLOUDS PATTERN HAS IMPROVED TEMPORARILY DURING THE PAST 6 HOURS. THE LOW LEVEL CIRCULATION CENTRE HAS BEEN RELOCATED SOUTH OF THE ANALIZED POSITION AT 06TU.
LOW LEVEL CIRCULATION CENTRE IS STILL EXPOSED EAST OF THE DEEP CONVECTION.

ENVIRONMENTAL CONDITIONS ARE NOT FAVORABLE FOR INTENSIFICATION OVER THE STAGE OF TROPICAL DEPRESSION.
LOW LEVEL INFLOW IS GOOD POLEWARD BUT IS RATHER POOR EQUATORWARD.
SYSTEM IS LOCATED NORTH OF THE UPPER LEVEL RIDGE AXIS AND IS UNDER THE INFLUENCE OF MOEDRATE EAST-NORTH-EAST UPPER LEVEL WIND SHEAR.
HOWEVER WIND SHEAR EFFECT IS LIMITED IN RELATION WITH THE SOUTHWESTWARD MOVEMENT OF THE SYSTEM.

POTENTIAL FOR INTENSIFICATION BEYOND THE TROPICAL DEPRESSION STAGE IS ALSO LIMITED.

MOST OF THE NWP MODELS FORECAST A TRACK SOUTH-WESTWARD RATHER SLOWLY WITHIN THE NEXT 48 HOURS, THEN SYSTEM SHOULD ACCELERATE SLIGHTLY WEST-SOUTH-WESTWARD.

Importante golpe convectivo que ha cogido en las ultimas  6 horas...

AS IT UNDERGOES THE REBUILDING SUBTROPICAL HIGH PRESSURES, SYSTEM IS
EXPECTED TO GRADUALLY SLOW DOWN AND RECURVE SOUTHWESTWARDS THEN WESTWARDS
.
ENVIRONMENTAL CONDITIONS WOULD REMAIN UNFAVOURABLE AND THE LOW LEVEL
CIRCULATION IS THEREFORE EXPECTED TO DISSIPATE IN THE TRADE WIND FLOW
WITHIN THE NEXT THREE DAYS.

Hola , Meteo France deja de seguir al  97-S

INFORMATION CYCLONE DU 04/01/2011 A 18:14 UTC

IL N'Y A PAS DE SYSTEME DEPRESSIONNAIRE TROPICAL ACTUELLEMENT EN COURS

De momento tranquilidad , y a la espera si el 97S  evoluciona un poco más...

Meteo France vuelve a seguir al sistema 97S

Actualmente posee 20 - 25 KT  1003 HPA

A mejorado respecto ayer.. pero poco futuro le ven al sistema.


Ultimo boletín  ( 5 Enero 11:57 UTC )

Déplacement : Ouest à 6 kt.

Pression estimée au centre : 1003 hPa.

Vent maxi : 10/15 kt atteignant localement 20/25 kt dans le
demi-cercle Sud loin du centre.


Pour les trois prochains jours, l'ensemble des modèles numériques
disponibles comblent lentement le minimum associé aux résidus de la
DT nr3 tout en le maintenant dans un lent déplacement  vers
l'Ouest. Ils ne creusent pas le minimum situé au Sud-Ouest des
Seychelles. Le manque d'alimentation avec un air particulièrement
sec dans les basses/moyennes couches est le principal facteur
manquant dans les deux cas. Seul le modèle ALADIN creuse des petits
minimums au-delà de 24 heures d'échéance, entre Madagascar et les
Seychelles, mais ce scénario semble peu vraisemblable.


Pour les prochaines  72 heures,

il n'y pas de risque de formation d'une dépression tropicale.

BULLETIN FOR CYCLONIC ACTIVITY AND SIGNIFICANT TROPICAL WEATHER IN
THE SOUTHWEST  INDIAN OCEAN

DATE: 2011/01/07 AT 1200 UTC

PART 1 :

WARNING SUMMARY :   Néant.

PART 2 :

 TROPICAL WEATHER DISCUSSION  :


Transequatorial flow persists West of 75E, and mainly West of 60E
and feeds two areas of convection  south-west of Seychelles Islands
and south of the Mozambique Channel.


South-west of Seychelles :

Convective activity is moderate and very fluctuating, located from
47E to 56E between 6S and 12S.   Within this activity, a weak low
level vortex is centered near 10S/51E at 10TU, almost stationnary,
with winds in range of 10/15 kt, and an estimated pression of
1008hPa. Equatoral and polar inflows are moderate. Upper level
vertical wind shear is weak to moderate.


In the south of the Mozambique Channel :

Convective activity is moderate to strong, located from 40E to 45E
and from 17S to 24S,  and concerns the western coast of Madagascar
from Besalampy to Toliara. Low level inflow is rather good but the
upper levels north-west vertical wind shear is strong ahead of an
upper tropospheric trough. According to the last animated satellite
pictures, convection isn't organized.

Remnants of Tropical Depression nr3 :

Fluctuating  convection remains located within the western part of
the exposed low level circulation.

Estimated position of the centre at 1100Z : 13.6S/71.0E

Motion: westward at 6 kt

Estimated minimum pressure : 1006 hPa

Maximum winds : 10/15 kt reaching 20 kt in the southern semi-circle
far away from the centre.


Within the next three days, the area of convection south of the
Mozambique Channel is expected to dig into the southern latitudes
and associated convective activity should edge away south-west of
Madagascar within the next 24 hours.

Remnants of Tropical Depression nr3 :

Fluctuating  convection remains located within the western part of
the exposed low level circulation.

Estimated position of the centre at 1100Z : 13.6S/71.0E

Motion: westward at 6 kt

Estimated minimum pressure : 1006 hPa

Maximum winds : 10/15 kt reaching 20 kt in the southern semi-circle
far away from the centre.

Within the next three days, the area of convection south of the
Mozambique Channel is expected to dig into the southern latitudes
and associated convective activity should edge away south-west of
Madagascar within the next 24 hours.
