Per GFS this system could become the first typhoon in this season

Per GFS this system could become the first typhoon in this season

I'd want 95W to be Malakas, because the name Malakas means strong, and 95W is located over an ocean with lots of space and warm water than 94W. I want Megi to be strong too when the name Megi became one of the deepest (885 mb) tropical cyclone thanks to a special recon at that time. Of course I want both to be their best.

Already 95W gets classification from dvorak SSD.

1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
A. TROPICAL CYCLONE SUMMARY: NONE.
B. TROPICAL DISTURBANCE SUMMARY:
(1) AN AREA OF CONVECTION (INVEST 95W) HAS PERSISTED NEAR 4.4N
18.3E, APPROXIMATELY 423 NM EAST-SOUTHEAST OF CHUUK. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY AND A 022334Z ASCAT-B PARTIAL PASS
REVEALS AN BROAD REGION OF ENHANCED NORTHEASTERLY AND NORTHERLY WIND
FLOW ALONG THE WESTERN PERIPHERY OF A DEVELOPING LOW LEVEL
CIRCULATION CENTER (LLCC). WHILE THE SCATTEROMETER PASS DOES NOT
DEFINE THE ACTUAL LLCC, IT PROVIDED ADDITIONAL CLARIFICATION TO THE
INITIAL POSITION. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI)
DEPICTS A BROAD REGION OF FLARING, BUT DISORGANIZED CONVECTION OVER
AND AROUND THE DEVELOPING LLCC. ENVIRONMENTAL ANALYSIS IS FAVORABLE
FOR DEVELOPMENT WITH LOW (5-10KTS) VERTICAL WIND SHEAR, GOOD RADIAL
OUTFLOW, AND WARM (29-30C) SEA SURFACE TEMPERATURES. GLOBAL
DETERMINISTIC AND ENSEMBLE ODELS ARE IN GENERAL AGREEMENT THAT
INVEST 95W WILL CONTINUE ON A WEST-NORTHWEST TRACK OVER THE NEXT
SEVERAL DAYS, WHILE QUICKLY CONSLIDATING. MODELS SHOW SOME
DISPARITIES REGARDING INTENSIFICATION, WITH GFS BEING THE MOST
AGGRESSIVE, REACHING TROPICAL DEPRESSION STRENGTH WITHIN 48 HOURS,
WHILE THE ECMWF IS A BIT SLOWER, NOT REACHING DEPRESSION STRENGTH
UNTIL ABOUT 72 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED
AT 15 TO 20 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 LOW.

NEAR 4.4N 158.3E IS NOW LOCATED NEAR 4.4N 157.0E, APPROXIMATELY 352
NM EAST-SOUTHEAST OF CHUUK. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
INDICATES STRONG MID-LEVEL TURNING OVER A BROAD, WEAKLY-DEFINED LOW-
LEVEL CIRCULATION (LLC). FAVORABLE CONDITIONS CHARACTERIZED BY
STRONG UPPER-LEVEL DIFFLUENCE AND LOW VERTICAL WIND SHEAR CONTINUE
TO FUEL LOOSELY ORGANIZED DEEP CONVECTION OVER THE SYSTEM. ALTHOUGH
THE SYSTEM REMAINS BROAD, THE LLC IS LOCATED NORTH OF A STRONG
WESTERLY WIND BURST WITH EXTENSIVE SOUTHEASTERLY FLOW CONVERGING
INTO THE EASTERN PERIPHERY OF THE SYSTEM. WARM (29-30C) SEA SURFACE
TEMPERATURES REMAIN CONDUCIVE FOR FURTHER DEVELOPMENT. GLOBAL MODELS
INDICATE STEADY INTENSIFICATION AND CONSOLIDATION WITH A WEST-
NORTHWESTWARD TRACK. GFS AND NAVGEM FORM A MINIMAL TROPICAL CYCLONE
WITHIN THE NEXT TWO DAYS WHILE ECMWF SHOWS SLOWER DEVELOPMENT AND A
TROPICAL DEPRESSION. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED
AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE
NEAR 1006 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS MEDIUM.

Looks like 95W is the precursor to the low-rider typhoon that the GFS, Euro, and CMC are showing. The first HWRF run for 95W hasn’t fully loaded yet, but shows a compact typhoon undergoing RI in three days.

I’m excited for this system because it’ll be the first WPac storm to have 10-minute and floater coverage on Tropical Tidbits. Hopefully it turns away from the Philippines like on all of the 00z/06z models.
