Estrecho de Madagascar: No creo que salga nada del Invest situado en esa zona, pero GFS y Europeo están tontorrones y marcan algo de desarrollo de aquí a 48-72h. Habrá que estar atentos.
Pues sí. De Invest directamente a Tormenta Tropical. :-X
09SNINE.35kts-996mb-218S-429E
REMARKS:
161500Z POSITION NEAR 20.6S 43.2E.
TROPICAL CYCLONE 09S (NINE), LOCATED APPROXIMATELY 215 NM WEST-
SOUTHWEST OF ANTANANARIVO, MADAGASCAR, HAS TRACKED SOUTH-
SOUTHWESTWARD AT 10 KNOTS OVER THE PAST SIX HOURS. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY ALONG WITH A 161224Z SSMI MICROWAVE
IMAGE SHOWS A WELL DEFINED AND TIGHTLY WRAPPED LOW LEVEL CIRCULATION
CENTER (LLCC) WITH DEEPENING CENTRAL CONVECTION AND IMPROVED
BANDING. THE INITIAL POSITION IS BASED UPON THIS WELL MARKED LLCC
SEEN IN THE AFOREMENTIONED IMAGERY WITH HIGH CONFIDENCE. THE CURRENT
INTENSITY HAS BEEN INCREASED TO TROPICAL CYCLONE STRENGTH (35 KNOTS)
BASED UPON THE TIGHTLY WRAPPED STRUCTURE OF THE SYSTEM AND IS
SLIGHTLY HIGHER THAN DVORAK INTENSITY ESTIMATES OF 30 KNOTS FROM ALL
REPORTING AGENCIES. UPPER LEVEL ANALYSIS INDICATES THE SYSTEM IS
UNDERNEATH A RIDGE AXIS IN AN AREA OF LOW (05-10 KNOT) VERTICAL WIND
SHEAR (VWS) AND EXCELLENT DUAL CHANNEL OUTFLOW, ONE CHANNEL
NORTHWESTWARD AND ANOTHER TOWARDS THE SOUTHEAST INTO THE MIDLATITUDE
WESTERLIES. TC 09S IS CURRENTLY TRACKING SOUTH ALONG THE WESTERN
PERIPHERY OF A SUBTROPICAL RIDGE (STR) POSITIONED TO THE EAST OF THE
SYSTEM. THIS STR WILL BE THE DOMINANT STEERING INFLUENCE THROUGH THE
NEXT 36 HOURS AS IT DRIVES THE SYSTEM TO THE SOUTH-SOUTHWEST.
BETWEEN TAU 36 AND TAU 48, ANOTHER RIDGE WILL BUILD IN FROM THE
WEST, WHICH WILL INITIALLY SLOW THE SYSTEM AS IT SWITCHES STEERING
INFLUENCES. AFTER TAU 48, THIS WESTERN STR WILL DRIVE TC 09S TO THE
NORTHWEST TOWARDS THE COAST OF MOZAMBIQUE. THE SYSTEM WILL STRUGGLE
TO INTENSIFY THROUGH THE NEXT 12 HOURS AS IT TRACKS ALONG THE COAST
OF MADAGASCAR. AFTER WHICH, WARM SEA SURFACE TEMPERATURES AND
FAVORABLE UPPER-LEVEL SUPPORT WILL ALLOW FOR GENERAL INTENSIFICATION
THROUGH TAU 48 TO A PEAK OF 50 KNOTS. AFTER THE SYSTEM BEGINS TO
TRACK TO THE NORTHWEST, INCREASING VWS WILL SLOWLY WEAKEN THE SYSTEM
AS IT APPROACHES MOZAMBIQUE. AVAILABLE DYNAMIC MODEL GUIDANCE IS
GENERALLY IN GOOD AGREEMENT WITH THE FORECAST TRACK WHICH IS
POSITIONED CLOSE TO THE MULTI-MODEL CONSENSUS. HOWEVER, THERE IS
SOME SLIGHT VARIANCES IN THE TIMING OF THE TURN TO THE NORTHWEST AS
THE SYSTEM SWITCHES STEERING INFLUENCES. DUE TO THIS, THERE IS LOW
CONFIDENCE IN THE INITIAL FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 161200Z IS 8 FEET. NEXT WARNINGS AT 170300Z AND 171500Z.
THIS WARNING SUPERSEDES AND CANCELS REF A, JOINT TYPHOON WRNCEN
PEARL HARBOR HI 152000Z JAN 14 TROPICAL CYCLONE FORMATION ALERT
(WTXS21 PGTW 152000).//

Ojo con ADT que ya le otorga más de 45 kts. Y es que no hay más que ver la convección que va generando con el paso de las horas. Para aquellos que la quieran observar en directo, casi a tiempo real, tan solo entrar en el SAT24-Africa_zona de Madagascar. 8)

Sale la oficialidad, cuando ADT le da un poco más de fuerza. Las agencias solo le dan un pico de 45 kts. algo que ya ha cumplido con creces. :P

Baja a 40 kts. Su cercanía a tierra parece que le ha pasado factura. Veremos ahora que parece se va alejando del SW de la isla, si mejora algo.
-
En vez de recurvar hacia el WNW, ha seguido trayectoria hacia el SW, por lo que se aleja de las aguas cálidas y aumenta la cizalladura. Sigue su camino como "Baja remanente" y termina su seguimiento por las agencias.

Bonito "remolino" de nubes bajas, con algo de convección hacia el Sur de su centro, se observa esta mañana en el SAT.
