Gran sorpresa con este sistema, que parecía que no iba a alcanzar un gran desarrollo, debido a su cercanía a la línea ecuatorial, pero ha sido bajar de latitud y desviarse hacia el SW de Australia, para crecer hasta casi la Categoría 2 S.S. en la que disfruta en estos momentos, porque vamos, viendo el SAT y el OJO incipiente...... 21SIKOLA.70kts-970mb-149S-901E
En el JTWC todavía lo mantiene como "sistema tropical" sin más.
EDITO: Acabado de cocinar. Ni que me hubiesen oido.

060900Z POSITION NEAR 14.6S 89.5E.
TROPICAL CYCLONE 21S (IKOLA), LOCATED APPROXIMATELY 1497 NM WEST-
NORTHWEST OF LEARMONTH, AUSTRALIA, HAS TRACKED SOUTHEASTWARD AT
09 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY SHOWS THE RAPIDLY DEEPENING SYSTEM WITH GOOD SPIRALED
BANDING WRAPPING TIGHTLY INTO A WELL-DEFINED LOW LEVEL CIRCULATION
CENTER (LLCC). IN ADDITION TO THE MSI, A 060231 GPM 36GHZ IMAGE
SHOWS A CLEARLY DEFINED MICROWAVE EYE, GIVING GOOD CONFIDENCE IN THE
INITIAL POSITIONING OF THE SYSTEM. THE INTENSITY OF 65 KNOTS HAS
BEEN INCREASED BASED ON CONCURRENT DVORAK ESTIMATES FROM KNES AND
PTGW. UPPER LEVEL ANALYSIS SHOWS VIGOROUS POLEWARD OUTFLOW WHICH
OFFSETS THE MODERATE VERTICAL WIND SHEAR (VWS). THE CYCLONE IS
TRACKING ALONG THE SOUTHWEST PERIPHERY OF AN EXTENSION OF A DEEP-
LAYERED SUBTROPICAL RIDGE. TC 21S WILL CONTINUE TO TRACK TO THE
SOUTHEAST THROUGH THE FORECAST PERIOD AS THE STR CONTINUES TO
PROVIDE THE DOMINATE STEERING MECHANISM FOR THE SYSTEM. MODELS
SUGGEST THAT THERE WILL BE SOME INCREASE IN THE INTENSITY OF THE
SYSTEM OVER THE NEXT 12 HOURS AS UPPER LEVEL OUTFLOW CONTINUES TO
AID IN DEVELOPMENT. BEYOND THAT, EXPECT A MARGINAL UPPER LEVEL
ENVIRONMENT, INCLUDING INCREASING VWS, TO SLOWLY WEAKEN THE SYSTEM
THOUGH TAU 48. IN ADDITION TO THE INCREASING VWS, SEA SURFACE
TEMPERATURES AND OCEAN HEAT CONTENT WILL DECEASE AS THE SYSTEM DROPS
POLEWARD OF 24 DEGREES SOUTH, CAUSING THE SYSTEM TO RAPIDLY
DISSIPATE WITH COMPLETE DISSIPATION BY TAU 96 AT THE LATEST. NUMERIC
MODEL GUIDANCE IS IN VERY TIGHT AGREEMENT, LEADING TO HIGH 
CONFIDENCE TO THE JTWC TRACK FORECAST. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 060600Z IS 14 FEET. NEXT WARNINGS AT 062100Z AND 070900Z.
