2.B OTHER INFORMATIONS:
T AND CI=2.5

LOCATION OF THE LOW LEVEL CENTER HAS BEEN ESTIMATED ACCORDING TO
MICRO-WAVE DATA (MAINLY TRMM AT 0710Z, WHICH SHOWS A GOOD ORGANZATION
OF
THE LOW LEVEL CIRCULATION AND A CURVED BAND OF DEEP CONVECTION STILL
LIGHLTY EAST OF THE LLCC).

THIS CENTER IS TRACKING SLOWLY NORTWESTWARDS, IT SHOULD MAKE A SMALL
LOOP
ON THE NORTHERN EDGE OF SUBTROPICAL HIGH PRESSURES CENTERED SOUTH OF
MADAGASCAR) BEFORE TRACKING MORE CLEARLY SOUTHWARDS DURING THE NEXT
24
HOURS, AFTER THE SHIF EASTWARDS OF THOSE SUBTROPICAL HIGH PRESSURES,
FOLLOWED BY A POL
AR TROUGH COMING FROM THE SOUTHWEST OVER THE SOUTH OF THE MOZAMBIC
CHANNEL.

IT SHOULD THEN START TO INTENSIFY RATHER RAPIDLY IN A FAVORABLE
ENVIRONMENT (SST BETWEEN 29 AND 30 CELSIUS DEGREES OVER THE
FORECASTED
TRACK, GOOD LOW LEVEL INFLOWS AND UPPER LEVEL OUTFLOWS - SEE 200 HPA
LEVEL).

THE WEAKENING OF THE OF THE TRADE WINDS INFLOW (DU TO THE SHIFH OF
HIGH
PRESSURES) SHOULD BE COMPENSATED BY AN ENHANCED POLEWARDS UPPER LEVEL
OUTFLOW (AN UPPER LEVEL TROUGH SHOULD BUILD SOUTWESTWARD OF THE
SYSTEM).=

CIMSS has upgraded this system to Tropical Storm 09S........ So, its name should be ELNUS, isn't it?

REMARKS:
311500Z POSITION NEAR 18.1S 41.1E.
TROPICAL CYCLONE (TC) 09S (NONAME), LOCATED APPROXIMATELY 345 NM
WEST OF ANTANANARIVO, MADAGASCAR, HAS BEEN QUASISTATIONARY OVER THE
PAST 06 HOURS. THE STORM HAS STRENGTHEN TO A SIGNIFICANT TC DUE TO FAVOR-
ABLE WATER AND AN UPPER LEVEL ANTICYCLONE JUST NORTHEAST OF THE LOW
LEVEL CIRCULATION WHICH HAS PROVIDED GOOD OUTFLOW AND LOW VERTICAL
WIND SHEAR. THE STORM IS CAUGHT IN A WEAK STEERING ENVIRONMENT, BETWEEN
TWO ANTICYCLONES TO THE WEST AND EAST. AN APPROACHING MIDLATITUDE TROUGH
OVER THE SOUTHERN ATLANTIC WILL CAUSE THE ANTICYCLONE TO THE WEST OF TC
09S TO BUILD TO NORTH AND EAST AND BECOME THE PRIMARY STEERING INFLUENCE
OF TC 09S. THE GRADUAL TRANSITION WILL CAUSE A SLOW SOUTH-SOUTHWESTWARD
TRACK OVER THE NEXT 48 HOURS. THE RELATIVELY SLOW MOVEMENT POLEWARD WILL
KEEP THE STORM OVER WATERS WITH FAVORABLE OCEAN HEAT CONTENT. THIS COUPLED
WITH CONTINUED POLEWARD AND EQUATORWARD OUTFLOW WILL ALLOW THE STORM TO
INTENSIFY OVER THE END OF THE FORECAST PERIOD. OVERALL, DYNAMICAL AIDS
ARE IN GOOD AGREEMENT WITH BOTH THE TRACK AND INTENSITY FORECAST. HOWEVER,
GIVEN THE HISTORICAL TRENDS OF THE REGION AND THE WEAK STEERING ENVIRONMENT
THIS STORM WILL BE CLOSELY MONITOR FOR ERRATIC MOVEMENT. THIS WARNING
SUPERSEDES AND CANCELS REF A, NAVPACMETOCCEN 301721Z DEC 07 TROPICAL
CYCLONE FORMATION ALERT (WTXS21 PGTW 301730). MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 311200Z IS 10 FEET. NEXT WARNINGS AT 010300Z AND 011500Z. REFER
TO TROPICAL CYCLONE 08S (MELANIE) WARNINGS (WTXS31 PGTW) FOR TWELVE-HOURLY
UPDATES.//

澳大利亚不是不认为它能够生成热带旋风么?

BoM, Australia doesn't think that it will become a tropical cyclone later, am I right?

ELNUS SHOWS A CURVED BAND PATTERN WITH 6/10 BANDING ON THE LAST IR
IMAGERY AND HAS THEN REACHED THE MINIMAL STAGE OF MODERATE TROPICAL
STORM
.


THIS CENTER HAS SLOWLY TRACKED SOUTHWARDS OVER THE LAST HOURS. IT
SHOULD
KEEP ON ON TRACKING GLOBALLY SOUTHWARDS OVER THE NEXT RANGES AS THE
SUBTROPICAL HIGH PRESSURES CENTERED SOUTH OF MADAGASCAR SHIFT
EASTWARDS
AND AS A TROUGH BUILDS FROM THE SOUTHWEST.

ENVIRONMENT IS VERY FAVORABLE FOR AN INTENSIFICATION OF THE SYSTEM
(SST
BETWEEN 29 AND 30 CELSIUS DEGREES ALONG THE FORECASTED TRACK, GOOD
LOW
LEVEL INFLOWS AND UPPER LEVEL OUTFLOWS - REFER TO 200 HPA LEVEL).

THE WEAKENING OF THE TRADE WINDS INFLOW (DUE TO THE SHIFT OF HIGH
PRESSURES) SHOULD BE BALANCED BY AN ENHANCED POLEWARDS UPPER LEVEL
OUTFLOW (AN UPPER LEVEL TROUGH SHOULD BUILD SOUTWESTWARD OF THE
SYSTEM).

HAPPY NEW YEAR=

And as such, it is now in the SW Pacific:

(1) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 13.3S
133.3E IS NOW LOCATED NEAR 15.0S 135.1E, APPROXIMATELY 285 NM
EAST-SOUTHEAST OF DARWIN, AUSTRALIA. RECENT ANIMATED MULTISPECTRAL
SATELLITE IMAGERY SHOWS A WELL-DEFINED AREA OF LOW LEVEL CYCLONIC
TURNING OVER LAND, BUT TRACKING EASTWARD TOWARD THE GULF OF
CARPENTARIA. PRESSURE FALLS AT THE CENTER ARE NEAR 2 MB IN 24
HOURS. A 310100Z TRMM IMAGE SHOWS CONVECTIVE BANDING ON SOUTHERN
PERIPHERY OF THE DISTURBANCE. UPPER LEVEL ANALYSIS REVEALS A 200
MB ANTICYCLONE HAS DEVELOPED JUST TO THE EAST OF THE LOW LEVEL
CIRCULATION CENTER (LLCC), CAUSING VERTICAL WIND SHEAR VALUES TO
LOWER. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 995 MB.
SINCE THE SYSTEM IS TRACKING CLOSER TO THE COAST AND THE UPPER
LEVEL CONDITIONS ARE IMPROVING, THE POTENTIAL FOR THE DEVELOPMENT
OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS
REMAINS FAIR. THIS AREA WAS PREVIOUSLY DISCUSSED ON THE ABIO
BULLETIN BUT HAS NOW CROSSED OVER INTO THE ABPW BULLETIN AREA,
EAST OF 135E (SEE REF A).


This is gone from NRL, but I imagine this is due to a technical problem (Elnus and Melanie are both missing as well).

Moderate Tropical Storm, not Tropical Cyclone. "Tropical Cyclone" is a category in this region (64 kts), so it's incorrect to call this "Tropical Cyclone Elnus".
