Re: WPAC: INVEST 94W
Models are confused
CMC
It strikes Guam as a near typhoon and then absorbs what is east of the Philippines (Which GFS is developing into a monster typhoon) and peaks around the Okinawa area...

Re: WPAC: INVEST 94W
AN AREA OF CONVECTION HAS PERSISTED NEAR 7.1N 145.8E,
APPROXIMATELY 380 NM SOUTH OF ANDERSON AFB, GUAM. ANIMATED EIR SHOWS
AN ELONGATED LLCC WITH PERSISTENT CONVECTION SHEARED TO THE WEST DUE
TO 15 TO 20 KNOT EASTERLY VWS. EXCELLENT DIFFLUENCE ALOFT IS
PARTIALLY OFFSETTING THE VWS. A 281148Z METOP-A 89GHZ MICROWAVE
IMAGE FURTHER SHOWS A WELL DEFINED, BUT ELONGATED CIRCULATION WITH
MINIMAL CONVECTION ALONG THE WESTERN PERIPHERY. GLOBAL MODELS
INDICATE POSSIBLE WEAK DEVELOPMENT AS THE DISTURBANCE TRACKS SLOWLY
EASTWARD. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15
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.

THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 9.1N
148.9E, IS NOW LOCATED NEAR 8.5N 148.8E, APPROXIMATELY 181 NM WEST
OF FANANU. RECENT ANIMATED MSI DEPICTS AN ELONGATED SIGNATURE WITH
THE BULK OF THE DEEP CONVECTION LOCATED TO THE SOUTH OF THE LLCC. A
300002Z METOP-A ASCAT PASS SHOWS A 10 TO 15 KNOTS CIRCULATION WITH
SLIGHTLY STRONGER 15 TO 20 KNOT ALONG THE SOUTHERN PERIPHERY. UPPER-
LEVEL ANALYSIS INDICATES THE DISTURBANCE IS LOCATED IN AN AREA OF
LOW VERTICAL WIND SHEAR WITH FAIR DIFFLUENT OUTFLOW. ADDITIONALLY,
WARM SSTS ARE CONDUCIVE FOR DEVELOPMENT. MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1007 MB. DUE TO PERSISTENT CONVECTIVE STRUCTURE
AND IMPROVING ENVIRONMENT, THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS MEDIUM.

Re: WPAC: INVEST 94W
JMA merges this with the Philippine system and becomes a strengthening TS or it could be the other way around...
NAVGEM doesn't merge this with 95W or the Philippine system. It passes it south of Guam as a strong TS to a typhoon interacting with another typhoon to the east...
CMC merges this with 95W...
EURO also merges this with 95W...

Re: WPAC: INVEST 94W
Looks the the majority doesn't strengthen this that much...
JMA gets this absorbed into Chan-hom
So does NAVGEM
So does EURO
So does GFS
But CMC as a tropical storm also gets absorbed...
