With exception Euro, models want to develop this. 00z

Looks like 2025 might not beat 1984 after all if this becomes a TS before June 9

[Hayabusa]

Euro AI tracks towards the Philippines but only developing it when it's over the South China Sea

1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
A. TROPICAL CYCLONE SUMMARY: NONE.
B. TROPICAL DISTURBANCE SUMMARY:
(1) AN AREA OF CONVECTION (INVEST 92W) HAS PERSISTED NEAR 9.8N
136.4E, APPROXIMATELY 106 NM WEST OF YAP, MICRONESIA. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY (MSI) AND A 042045Z SSMIS 91GHZ
MICROWAVE IMAGE DEPICT A SLOWLY CONSOLIDATING RAGGED DEEP CONVECTIVE
BANDING OBSCURING THE LOW-LEVEL CIRCULATION CENTER. ENVIRONMENTAL
ANALYSIS REVEALS A MODERATE TO FAVORABLE ENVIRONMENT WITH LOW VERTICAL
WIND SHEAR (VWS) OF 10-15 KNOTS, MODERATE EQUATOR OUTFLOW, AND WARM SEA
SURFACE TEMPERATURES OF 30-31C. DETERMINISTIC AND ENSEMBLE MODELS ARE
IN GOOD AGREEMENT REVEALING GRADUAL DEVELOPMENT OVER THE NEXT FEW DAYS.
THE MODEL GUIDANCE BETWEEN GFS AND ECMWF INDICATE VARYING TIMELINES OF
DEVELOPMENT. HOWEVER, 92W IS LIKELY TO DEVELOP IN THE NEAR TERM DESPITE
A TUTT CELL INDUCING THE 10-15KT VERTICAL WIND SHEAR FROM THE NORTH
WHILE THE TUTT ALSO FAVORABLE ENHANCES OUTFLOW POLEWARD. MAXIMUM
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 13 TO 18 KNOTS. MINIMUM SEA
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1010 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.

THE ELONGATED NATURE OF THE CIRCULATION WITH 10 KNOT WINDS ALONG THE
NORTHERN AND EASTERN PERIPHERIES OF THE SYSTEM. ENVIRONMENTAL ANALYSIS
REVEALS A MODERATELY FAVORABLE ENVIRONMENT, WITH MODERATE EQUATORWARD
OUTFLOW ALOFT AND LOW TO MODERATE VERTICAL WIND SHEAR (VWS) OF 15-20
KNOTS. 92W WILL ALSO HAVE WARM SEA SURFACE TEMPERATURES OF 30-31C TO
HELP DEVELOPMENT. GLOBAL DETERMINISTIC AND ENSEMBLE MODELS ARE CURRENTLY
IN GOOD AGREEMENT ON A WESTWARD TRACK INTO THE SOUTH CHINA SEA OVER THE
NEXT 48 HOURS WITH STEADY INTENSIFICATION AS THE SYSTEM CONSOLIDATES.

SUBJ/TROPICAL CYCLONE FORMATION ALERT (INVEST 92W)//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
120 NM EITHER SIDE OF A LINE FROM 15.3N 114.5E TO 17.0N 109.9E
WITHIN THE NEXT 12 TO 24 HOURS. AVAILABLE DATA DOES NOT JUSTIFY
ISSUANCE OF NUMBERED TROPICAL CYCLONE WARNINGS AT THIS TIME.
WINDS IN THE AREA ARE ESTIMATED TO BE 18 TO 23 KNOTS. METSAT
IMAGERY AT 100600Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 15.4N 114.2E. THE SYSTEM IS MOVING WEST-NORTHWESTWARD AT 06
KNOTS.
2. REMARKS: THE AREA OF CONVECTION (INVEST 92W) PEVIOUSLY LOCATED NEAR
15.2N 115.7E IS NOW LOCATED NEAR 15.2N 114.8E, APPROXIMATELY 349 NM
EAST OF DA NANG. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS
AN EXPOSED LOW LEVEL CIRCULATION CENTER (LLCC), WITH FORMATIVE LOW-LEVEL
BANDING WRAPPING INTO THE LLCC. A PARTIAL 100223Z ASCAT (METOP-C)
MICROWAVE IMAGE SHOWS A CLOSED CIRCULATION WITH THE STRONGEST WINDS
(APPROXIMATELY 20KTS) AROUND THE SOUTHERN PORTION OF THE INVEST.
ENVIRONMENTAL ANALYSIS REVEALS FAVORABLE CONDITIONS FOR DEVELOPMENT WITH
GOOD EQUATORWARD UPPER-LEVEL OUTFLOW, WARM SEA SURFACE TEMPERATURES
(SST) OF 29-30C, AND LOW TO MODERATE WIND SHEAR (15-20 KNOTS).
DETERMINISTIC AND ENSEMBLE MODELS ARE IN GOOD AGREEMENT THAT 92W WILL
DEVELOP WHILE TRACKING TOWARDS THE NORTHWEST OVER THE NEXT 24 HOURS.
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23 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 HIGH.
