JTWC評級Low
(1) AN AREA OF CONVECTION (INVEST 93P) HAS PERSISTED NEAR 9.7S
156.2E, APPROXIMATELY 225 NM WEST OF HONIARA, SOLOMON ISLANDS.
ANIMATED ENHANCED MULTISPECTRAL SATELLITE IMAGERY DISPLAYS LOW LEVEL
CLOUD LINES WRAPPING INTO A BROAD LLCC (LOW LEVEL CIRCULATION
CENTER) WITH FLARING, DISORGANIZED CONVECTION. A 072251Z METOP-C
PASS SHOWS 10-15KT WINDS AROUND A LARGE CIRCULATION CENTER.
ENVIRONMENTAL ANALYSIS REVEALS THAT THE CIRCULATION IS IN AN AREA OF
MARGINALLY FAVORABLE DEVELOPMENT DEFINED BY WARM SST (30-31C) AND
LOW TO MODERATE VERTICAL WIND SHEAR. THE OUTFLOW IS NOTABLE WITH
ENHANCED POLEWARD OUTFLOW FEEDING INTO THE JET TO THE SOUTH. GLOBAL
MODELS ARE IN AGREEMENT THAT THE SYSTEM WILL GENERALLY TRACK
SOUTHEASTWARD OVER THE NEXT 24-48 HOURS. MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 10 TO 15 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 LOW.

BoM編號07U
A weak tropical low (07U) may develop in the far northeast of the region near the Solomon Sea on Thursday or Friday. This system should move towards the south to southeast, and may develop over the weekend. It is expected to remain in the eastern Coral Sea, and will not directly impact Queensland communities.


Likelihood of a tropical cyclone in the Eastern Region on:
Thursday:Very Low
Friday:Very Low
Saturday: Low

MICROWAVE IMAGE DEPICT A LOW-LEVEL CIRCULATION CENTER WITH DEEP
CONVECTION TO THE NORTHERN PERIPHERY. IN ADDITION, FORMATIVE BANDING
WRAPS INTO THE CENTER TO THE WEST AND SOUTH. ENVIRONMENTAL ANALYSIS
INDICATES FAVORABLE CONDITIONS FOR DEVELOPMENT WITH STRONG POLEWARD
OUTFLOW, WEAK (05-10KTS) VERTICAL WIND SHEAR, AND VERY WARM (30-31C)
SEA SURFACE TEMPERATURES. GLOBAL MODELS ARE IN AGREEMENT ON THAT 93P
WILL TRACK EAST-SOUTHEAST AND CONTINUE TO INTENSIFY TO TROPICAL
DEPRESSION STRENGTH OVER THE NEXT 24-48 HOURS.  MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 1004 MB. THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS HIGH.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY

REMARKS:
Location is based on animated IR.

The system has shown increased organisation over the past 24 hours with deep
convection on the southern side wrapping around the western side. For now, the
wrap of deep convection remains segmented. Dvorak analysis using curved band
measures 0.3 wrap on the western band, yielding a DT=2.0. However there is low
confidence in DT due to the segmented nature of convection. A D- trend produces
MET=1.5, FT is based on PT=2.0. Objective guidance isn't available yet. Maximum
winds are estimated around 25 knots.

The system is in area of low shear with under the influence of an upper ridge
to it's northeast. CMISS indicates an upper trough located over eastern
Australia is providing strong upper divergence to the south of the system.
MIMIC TPW indicates a very moist environment. SSTs are 29-30C in the area.  

NWP is inconsistent with intensification rates. Many of the higher resolution
models are producing an unusually symmetrical and stronger system with an
indication of steep intensification in the 24 to 48 hour period. While others
have a slowly developing system with the stronger winds predominantly on the
eastern side. While conditions are mostly favourable for development, vertical
wind shear amy increase substantially as the upper trough to the west becomes
more influential. A Dvorak standard rate of development is forecast with a
category 3 system approaching New Caledonia early next week.   

Global and high res model guidance are consistent with the system moving
southeastwards during the weekend ahead of the approaching upper trough to the
west.
