Tropical Low 01F SE of Papua New Guinea (ex-93P)

[Coredesat]

Appeared earlier, this would be the first invest of the 2007-08 year for the Southwest Pacific:

I think that would be our equivalent of April down there.

B. TROPICAL DISTURBANCE SUMMARY:
(1) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 8.1S
165.4E, IS NOW LOCATED NEAR 8.2S 165.1E, APPROXIMATELY 265 NM EAST
OF AUKI HARBOR, SOLOMON ISLANDS. ANIMATED ENHANCED INFRARED IMAGERY
AND A 170606 SSMI MICROWAVE IMAGE SHOWS FLARING CONVECTION WHICH IS
SLOWLY ORGANIZING AROUND AN ASYMMETRIC LOW LEVEL CIRCULATION CENTER.
UPPER LEVEL ANALYSIS REVEALS GOOD CROSS-EQUATORIAL AND POLEWARD
OUTFLOW IN ADDITION TO WEAK VERTICAL WIND SHEAR ALOFT. MAXIMUM
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1005 MB. THE POTENTIAL FOR
THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS UPGRADED TO FAIR.

Tropical Disturbance Summary For area Equator to 25S, 160E to 120W
ISSUED FROM RSMC NADI Oct 17/2329 UTC 2007 UTC.

TROPICAL DEPRESSION 01F [1000HPA] ANALYSED NEAR 10.4S 166.0E AT
172100Z SLOWLY MOVING WESTWARD. POSITION POOR BASED ON GMSIR/VIS WITH
ANIMATION. SST IN THE AREA IS AROUND 29C.

AT THIS STAGE IT IS DIFFICULT TO JUDGE WHERE THE LLCC IS LOCATED BUT
RECENT VIS AND IR IMAGES SHOW ACTIVE CONVECTIVE CLOUD BANDS IN THE
VICINITY. CIMMS INDICATES THAT 01F REMAINS IN A LOW SHEAR ENVIROMENT
WITH AN AREA OF STRONG SHEAR TO THE SOUTHWEST OF THE SYSTEM. 01F
CURRENTLY LIES UNDER AN UPPER LEVEL RIDGE, HOWEVER, A WESTERLY SHEAR
IS LOCATED JUST SOUTH OF THIS UPPER LEVEL RIDGE AND SEEMS TO BE
ACTING ON THE CLOUD CLUSTER IN THE WESTERN QUADRANT. AN ACTIVE
CONVERGENCE ZONE TO THE NORTH WITH ASSOCIATED CLOUD BAND AND
NORTHWESTERLY FLOW SUPPORT THE SYSTEM WHILE A GOOD SOUTHEASTERLY FLOW
IS EVIDENT TO THE SOUTH. CLOUD TOPS ACCORDING TO SATELLITE IMAGERY
SHOW THAT THEY ARE WARMING AND ORGANSITION REMAINS DETACHED FROM
ANALSYED LLC.
MOST GLOBAL MODELS [ECMWF,GASP,GFS,TXLAPS] HAVE PICKED UP THE SYSTEM
BUT DO NOT HAVE IT DEEPING OR DEVELOPING ANY FURTHER IN THE NEXT 24
HOURS. ECMWF HAS 01F MOVING SOUTHWEST WHILE MOST OTHER MODELS HAVE IT
MOVING GENERALLY SOUTHWARD.
POTENTIAL FOR 01F TO DEVELOP INTO A TROPICAL CYCLONE IN THE NEXT 24
HOURS IS LOW TO MODERATE.

NO OTHER SIGNIFICANT TROPICAL DISTURBANCES ANALYSED OR FORECAST IN
THE AREA.

Looking a little better. WPAC Floater 2 is over this system.

Gone from NRL. If this doesn't appear in Nadi's next tropical disturbance summary, I'll archive this.

And that would be it.
