1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
A. TROPICAL CYCLONE SUMMARY:
(1) AT 25JUL24 0000Z, TYPHOON 05W (GAEMI) WAS LOCATED NEAR 25.1N
120.2E, APPROXIMATELY 71 NM WEST OF TAIPEI, TAIWAN, AND HAD TRACKED
WEST-NORTHWESTWARD AT 12 KNOTS OVER THE PAST SIX HOURS. MAXIMUM
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 75 KNOTS GUSTING TO 90 KNOTS.
SEE REF A (WTPN32 PGTW 250300) FOR FURTHER DETAILS.
(2) NO OTHER TROPICAL CYCLONES.
B. TROPICAL DISTURBANCE SUMMARY:
(1) AN AREA OF CONVECTION (INVEST 95W) HAS PERSISTED NEAR 6.8N
135.4E, APPROXIMATELY 58.5 NM SOUTHEAST OF PALAU. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY (MSI) DEPICTS A BROAD SLIGHTLY OBSCURED LOW LEVEL
CIRCULATION CENTER (LLCC) WITH PERSISTENT CONVECTIVE FLARING ON THE
NORTHERN PERIPHERY RESPECTIVELY. ENVIRONMENTAL ANALYSIS SHOWS FAVORABLE
CONDITIONS FOR FURTHER DEVELOPMENT OF INVEST 95W WITH WARM (29-30C) SST,
WEAK UPPER LEVEL OUTFLOW DUE TO THE DOMINANT PRESENCE OF TY 05W, AND LOW
TO MODERATE (15-20KTS) VWS. DETERMINISTIC MODEL GUIDANCE SHOWS POOR
AGREEMENT ON DEVELOPMENT CYCLE OF 95W WITH GFS AND NAVGEM SHOWING
DISTURBANCE STRENGTH BY TAU 60 WHILE ECMWF LEANING MORE ON THE LOWER
SIDE WITH JUST TROUGHING, BUT THERE IS STILL HOPE WITH ALL AGREEING ON A
RELATIVELY NORTHWESTWARD TRACK SIMILAR TO 05W. GEFS AND ECENS ENSEMBLES
SHOW STRONG MEMBER SIGNATURES THROUGHOUT WITH GOOD AGREEMENT ON A
NORTHWESTWARD TRACK AS WELL. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 13 TO 18 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO
BE NEAR 1007 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.
(2) NO OTHER SUSPECT AREAS.
C. SUBTROPICAL SYSTEM SUMMARY: NONE.
2. SOUTH PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST):
A. TROPICAL CYCLONE SUMMARY: NONE.
B. TROPICAL DISTURBANCE SUMMARY: NONE.
C. SUBTROPICAL SYSTEM SUMMARY: NONE.//

00Z, models have it tracking similar to Gaemi but significantly weaker but let's see

1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
A. TROPICAL CYCLONE SUMMARY:
(1) AT 25JUL24 1200Z, TROPICAL STORM 05W (GAEMI) WAS LOCATED NEAR
25.6N 119.4E, APPROXIMATELY 118 NM WEST-NORTHWEST OF TAIPEI, TAIWAN, AND
HAD TRACKED NORTHWESTWARD AT 05 KNOTS OVER THE PAST SIX HOURS. MAXIMUM
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 50 KNOTS GUSTING TO 65 KNOTS.
SEE REF A (WTPN32 PGTW 251500) FOR THE FINAL WARNING ON THIS SYSTEM.
(2) NO OTHER TROPICAL CYCLONES.
B. TROPICAL DISTURBANCE SUMMARY:
(1) THE AREA OF CONVECTION (INVEST 95W) PREVIOUSLY LOCATED NEAR
7.3N 134.8E IS NOW LOCATED NEAR 6.6N 134.8E, APPROXIMATELY 43 NM SOUTH
OF PALAU. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) AND A 252059Z
89GHZ SSMIS PASS DEPICTS A BROAD AREA OF DENSE CONVECTION AS WELL AS
FORMATIVE AND FRAGMENTED LOW-LEVEL BANDING FEATURES WRAPPING INTO A
BROAD LOW LEVEL CIRCULATION CENTER (LLCC) WITH PERSISTENT CONVECTION IN
THE WESTERN PORTION. ENVIRONMENTAL ANALYSIS INDICATES FAVORABLE
CONDITIONS FOR FURTHER DEVELOPMENT OF INVEST 95W WITH WARM (29-30C) SST,
A DEVELOPING POINT SOURCE LOCATED IN THE VICINITY OF 95W IS ALLOWING FOR
GOOD DIVERGENCE ALOFT, AND A PREDOMINANTLY LOW (10-15KTS) VWS.
DETERMINISTIC MODEL GUIDANCE SHOWS GOOD AGREEMENT ON DEVELOPMENT CYCLE
OF 95W WITH A NORTHWESTWARD TRACK AND FURTHER CONSOLIDATION OVER THE
NEXT 24 TO 48 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18
TO 23 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1007 MB.
THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS UPGRADED TO MEDIUM.
(2) NO OTHER SUSPECT AREAS.
C. SUBTROPICAL SYSTEM SUMMARY: NONE.
2. SOUTH PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST):
A. TROPICAL CYCLONE SUMMARY: NONE.
B. TROPICAL DISTURBANCE SUMMARY: NONE.
C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 1.B.(1) TO
MEDIUM.////

RMKS/
1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
A. TROPICAL CYCLONE SUMMARY: NONE.
B. TROPICAL DISTURBANCE SUMMARY:
(1) THE AREA OF CONVECTION (INVEST 95W) PREVIOUSLY LOCATED NEAR
6.9N 133.9E IS NOW LOCATED NEAR 7.9N 133.4E, APPROXIMATELY 80 NM WEST-
NORTHWEST OF PALAU. ANIMATED VISIBLE SATELLITE IMAGERY DEPICTS A BROAD,
FULLY EXPOSED LOW-LEVEL CIRCULATION (LLC) WITH DISORGANIZED CONVECTION
FLARING TO THE NORTH. A 270401Z ATMS 88.2 GHZ MICROWAVE IMAGE ALSO
DEPICTS A BROAD, WEAKLY-DEFINED LLC WITH NO CONVECTIVE STRUCTURE. A
270023Z ASCAT-C IMAGE SHOWS NO DEFINED CIRCULATION WITH A TROUGH OVER
THE CENTER, EXTENDING NORTHWARD. ADDITIONALLY, WINDS NEAR THE CENTER ARE
LIGHT (5-10 KNOTS), WITH A SWATH OF 15-20 KNOT WINDS DISPLACED OVER 200
NM TO THE NORTH-NORTHEAST. SURFACE OBSERVATIONS FROM KOROR CITY (PTRO)
INDICATE SOUTH-SOUTHEASTERLY WINDS AT 5-10 KNOTS, WITH SLP NEAR 1008 MB
AND A 24-HOUR SLP INCREASE OF 1 MB. UPPER-LEVEL ANALYSIS INDICATES
UNFAVORABLE CONDITIONS FOR DEVELOPMENT WITH HIGH (30-35 KNOTS) NORTHERLY
VERTICAL WIND SHEAR (VERIFIED FROM THE 270000Z PTRO UPPER-AIR SOUNDING)
AND UPPER-LEVEL CONVERGENT FLOW. GLOBAL MODELS INDICATE NO SIGNIFICANT
DEVELOPMENT OF 95W, HOWEVER, THE GLOBAL MODELS DO WEAKLY DEVELOP ANOTHER
DISTURBANCE IN 12-24 HOURS FURTHER NORTH NEAR 13N 130E (NOW INVEST 96W).
BOTH THE GFS AND ECMWF ENSEMBLES ALSO INDICATE A DISTURBANCE LIKELY
FORMING NEAR THE NEW INVEST (96W). MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO
BE NEAR 1008 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS DOWNGRADED TO LOW.
