Position is only approximately based on animated satellite imagery and extrapolated motion since earlier HSCAT and microwave (GMI 1149UTC) imagery. Intensity 30kn based on earlier HSCAT scatterometry supported by Dvorak analysis FT/CI=2.0/2.5. DT not clear cut without curvature on EIR. MET=2.0 based on slight weakening 24h trend. Objective aids generally continue to provide anomalously high estimates for this system: ADT 49 kn; AiDT 43 kn; DMINT 39 kn; DPRINT 36 kn (1-min mean). The low is expected to track to the south as the mid-level ridge to the east gives way to an amplifying mid-level trough to the west of Australia. Within 12-24h the mid-level trough will steer the system more south-southeast to cross the WA coast. Confidence in the track forecast is high with agreement across the range of model guidance. The circulation has failed to developed despite some favourable influences of warm sea surface temperatures (SSTs) of ~28C, low wind shear and an established low level circulation. Deep convection has failed to become organised and sustained about the centre in the absence of significant low level moist inflow. There remains some opportunity in the next 6-12h for convection to become more enhanced especially with increasing upper level divergent flow poleward and sector gales may briefly occur. However, the window of opportunity is less than 12 h before higher wind shear allows dry air to intrude the core and then landfall lead to the demise of the circulation.

FOR METEOROLOGISTS. 2. 6 HOUR SUMMARY AND ANALYSIS. SUMMARY: INITIAL POSITION: 19.5S 113.4E INITIAL INTENSITY: 35 KTS GEOGRAPHIC REFERENCE: 173 NM NORTH-NORTHWEST OF LEARMONTH, AUSTRALIA MOVEMENT PAST 6 HOURS: SOUTH-SOUTHWESTWARD AT 04 KTS SIGNIFICANT WAVE HEIGHT: 15 FEET SATELLITE ANALYSIS, INITIAL POSITION AND INTENSITY DISCUSSION: ANIMATED CIRA PROXY VISIBLE IMAGERY DEPICTS AN ELONGATED AREA OF VIGOROUS BUT DISORGANIZED CONVECTION. THE LACK OF MICROWAVE IMAGERY OVER THE PAST SIX HOURS HAS HAMPERED IDENTIFICATION OF THE LOW LEVEL CIRCULATION CENTER (LLCC). OLDER SSMIS DATA SUGGESTS THE POSSIBILITY OF A BROAD LLCC. THE INITIAL POSITION WAS PLACED BASED ON THE PGTW FIX, HOWEVER, MULTI-AGENCY FIX SPREAD IS LARGE, LENDING LOW CONFIDENCE TO THE POSITIONING. THE SYSTEM HAS SLOWED AS IT ROUNDS THE MID-LEVEL SUB-TROPICAL RIDGE (STR) TO THE EAST. THE INITIAL INTENSITY WAS ASSESSED AT 35 KTS GIVEN MULTI-AGENCY DVORAK CURRENT INTENSITIES OF T2.5. OBJECTIVE GUIDANCE WAS LARGELY HIGHER, AND DEEMED UNREPRESENTATIVE BASED ON THE CURRENT SATELLITE PRESENTATION. ADDITIONALLY, THE PREVIOUS BEST TRACK WAS RE-ANALYZED DOWN TO 35 KNOTS. THE ENVIRONMENT IS MARGINALLY FAVORABLE, WITH CIMSS VERTICAL WIND SHEAR (VWS) BETWEEN 10 TO 15 KTS, AND INCREASING POLEWARD OUTFLOW ALOFT CONTRIBUTING TO A SLIGHTLY POLEWARD TILTED VORTEX. THE GFS INDICATES A TONGUE OF MID-LEVEL DRY AIR ALONG THE NORTHERN PERIPHERY. DESPITE FAVORABLE SSTS AROUND 29 DEGREES CELSIUS, TC 14P HAS STRUGGLED TO MAINTAIN A CONSOLIDATED LLCC. INITIAL WIND RADII BASIS: OBJECTIVE BEST TRACK. R34 WAS REDUCED BASED ON REANALYSIS OF PRIOR INTENSITY DOWN TO 35 KNOTS. CURRENT STEERING MECHANISM: MID-LEVEL STR TO THE EAST AGENCY DVORAK AND AUTOMATED FIXES: PGTW: T2.5 - 35 KTS KNES: T2.5 - 35 KTS APRF: T2.5 - 35 KTS CIMSS SATCON: 51 KTS AT 230930Z CIMSS ADT: 49 KTS AT 231930Z FORECASTER ASSESSMENT OF CURRENT ENVIRONMENT: MARGINALLY FAVORABLE VWS: 10-15 KTS SST: 29-30 CELSIUS OUTFLOW: STRONG POLEWARD ANALYSIS CONFIDENCE: INITIAL POSITION: LOW INITIAL INTENSITY: MEDIUM INITIAL WIND RADII: LOW 3. FORECAST REASONING. SIGNIFICANT FORECAST CHANGES: THERE ARE NO SIGNIFICANT CHANGES TO THE FORECAST FROM THE PREVIOUS WARNING. FORECAST DISCUSSION: TC 14P IS FORECAST TO CONTINUE ROUNDING THE STR, PRIMARILY TRACKING SOUTHWARD OVER THE NEXT 24 HOURS BEFORE TURNING BACK TO THE SOUTH-SOUTHEAST AND MAKING LANDFALL. MULTI-MODEL TRACK CONSENSUS IS IN GOOD AGREEMENT GIVEN THE STRAIGHT-FORWARD STEERING ENVIRONMENT. THE PEAK INTENSITY WAS HELD TO 35 KNOTS. TC LINCOLN HAS A SHORT WINDOW REMAINING FOR INTENSIFICATION. AFTER TAU 24, INCREASING VWS AND DRY AIR AS THE SYSTEM APPROACHES THE COAST SHOULD TAMPER ANY FURTHER DEVELOPMENT. RAPID DISSIPATION IS EXPECTED POST-LANDFALL. MODEL DISCUSSION: THE SYSTEM APPEARS TO BE OVER-ANALYZED IN THE GFS MODEL. ECMWF APPEARS TO BE MORE REALISTICALLY ANALYZING THE BROAD AND POORLY ORGANIZED LLCC, AND THIS MODEL IS LESS AGGRESSIVE FOR ANY ADDITIONAL INTENSIFICATION. DESPITE UNCERTAINTY IN THE INITIAL ANALYSIS, GOOD AGREEMENT ON TRACK AND INTENSITY GUIDANCE LENDS HIGH CONFIDENCE IN THE FORECAST.
