THE AREA OF CONVECTION (INVEST 90W) PREVIOUSLY LOCATED
NEAR 12.2N 128.9E, IS NOW LOCATED NEAR 10.0N 132.3E, APPROXIMATELY
210 NM NORTHWEST OF PALAU. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
SHOWS FLARING CONVECTION WITH SMALL CIRCULATIONS SURROUNDING AN
OVERALL BROAD CIRCULATION. A 040058Z METOP-A ASCAT PASS REVEALED
THAT THE SURFACE CIRCULATION WAS APPROXIMATELY 230 NM SOUTHEAST OF
THE PREVIOUS INVEST AREA. THE NEW LOCATION DEPICTS THIS RELOCATION.
A 040057Z MHS 89GHZ METOP-A MICROWAVE IMAGE REVEALS THERE IS
DISORGANIZED CONVECTION ASSOCIATED WITH THE BROAD CIRCULATION. UPPER
LEVEL ANALYSIS SHOWS THE DISTURBANCE IS LOCATED IN A FAVORABLE UPPER
LEVEL ENVIRONMENT WITH LOW (10-15 KTS) VERTICAL WIND SHEAR AND WEAK
DUAL OUTFLOW ALOFT. WARM SSTS EAST OF THE PHILIPPINES (28-29C) ARE
ALSO SUPPORTIVE FOR FUTURE DEVELOPMENT. GLOBAL MODELS INDICATE
DEVELOPMENT OF THE SYSTEM BUT VARY ON THE INTENSIFICATION AND TIMING
OF THE DEVELOPMENT. 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 REMAINS MEDIUM.

The models are again developing this and swallowing up 91W.

[euro6208]

[euro6208]

Two tropical disturbances remains north of Yap and Koror this
afternoon. The disturbance NW of Koror near 10N132E has been nearly
stationary for several days and appears to be the more dominant
feature as the other disturbance near 14N135E continues to show a
weakening trend. The monsoon trough remains north of Yap and Koror
and will slowly lift north. Moderate to fresh monsoonal flow will
persist south of these features pumping in gusty winds, choppy seas
and locally heavy rainfall across the region. Yap was under the gun
this morning with widespread showers and thunderstorms. Weather is
in a lull there this evening, but showers and thunderstorms are
filling in just southwest of Koror and inbound.

1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
200 NM EITHER SIDE OF A LINE FROM 9.9N 132.8E TO 16.9N 130.2E
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 051200Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 10.5N 132.5E. THE SYSTEM IS MOVING NORTHEASTWARD AT 08
KNOTS.
2. REMARKS:
THE AREA OF CONVECTION (INVEST 90W) PREVIOUSLY LOCATED NEAR 14.1
135.1E, IS NOW LOCATED NEAR 13.9N 131.5E, APPROXIMATELY 225NM
NORTHWEST OF PALAU. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY
DEPICTS RENEWED CONVECTION DIRECTLY OVER A PREVIOUSLY FULLY EXPOSED
LOW LEVEL CIRCULATION CENTER. THE ENVIRONMENT IS OVERALL FAVORABLE
FOR DEVELOPMENT, WITH LOW-MODERATE (10-20KTS) VWS AND VERY WARM (29-
31C) SSTS IN THE VICINITY. GLOBAL MODELS ARE IN STRONG AGREEMENT
THAT INVEST 90W, HAVING ABSORBED INVEST 91W, WILL INITIALLY TRACK TO
THE NORTHWEST AS A MONSOON DEPRESSION BEFORE TIGHTENING INTO A
TROPICAL CYCLONE. 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.

THE AREA OF CONVECTION (INVEST 90W) PREVIOUSLY LOCATED
NEAR 10.1N 131.9E, IS NOW LOCATED NEAR 12.7N 132.0E, APPROXIMATELY
360 NM NORTH-NORTHWEST OF PALAU. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY DEPICTS A VERY BROAD, PARTIALLY EXPOSED LLC WITH FLARING
CONVECTION BEGINNING TO WRAP IN. A 060115Z ASCAT PASS SHOWS THE
BROAD NATURE OF THE LLC, WITH SOME 25-30KT WINDS IN THE SOUTHWEST
QUADRANT. DESPITE THE HIGH WINDS, THE LLC IS NOT CLOSED OFF AND IS
TOO ILL DEFINED TO WARRANT A TROPICAL CYCLONE WARNING AT THIS TIME.
90W IS CURRENTLY UNDER A BROAD REGION OF LOW (10-15KT) VWS WITH
ADEQUATE DIVERGENCE ALOFT DUE TO FORMATIVE DUAL CHANNEL OUTFLOW.
SSTS REMAIN WARM (29-30C) EAST OF THE PHILIPPINES AND WILL SUPPORT
FURTHER DEVELOPMENT. GLOBAL MODELS ARE IN FAIRLY GOOD AGREEMENT ON
90W TRACKING NORTH-NORTHWEST OVER THE NEXT 12-48 HOURS AS THE WIND
FIELD INTENSIFIES AND TIGHTENS INTO A TROPICAL CYCLONE. 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 REMAINS HIGH.

It's certainly getting close to something worth classifying.

[euro6208]

Peak.

[euro6208]

[euro6208]

Is a very large system.

PO now into AW.. fish, thinks the ec . Good news if it verifys.

THE AREA OF CONVECTION (INVEST 90W) PREVIOUSLY LOCATED
NEAR 15.0N 130.5E, IS NOW LOCATED NEAR 13.1N 128.8E, APPROXIMATELY
760NM SOUTH-SOUTHEAST OF KADENA AB. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY AND A 061002Z 91GHZ SSMIS MICROWAVE IMAGE SHOW A
LARGE AREA OF FLARING CONVECTION ALONG THE SOUTHERN ARC WRAPPING
INTO A PARTIALLY EXPOSED LLC. THE UPPER LEVEL ENVIRONMENT REMAINS
OVERALL FAVORABLE FOR DEVELOPMENT, WITH LOW (10-15KT) VWS AND STRONG
DIVERGENCE ALOFT DUE TO FORMATIVE DUAL CHANNEL OUTFLOW. AN UPPER
LEVEL RIDGE TO THE NORTH OF THE SYSTEM IS CURRENTLY PREVENTING
STRONGER OUTFLOW. SSTS REMAIN VERY WARM (29-31C) IN THE PHILIPPINE
SEA. GLOBAL MODELS ARE IN GOOD AGREEMENT THAT INVEST 90W WILL TRACK
NORTHWEST THEN NORTHEAST OVER THE NEXT FEW DAYS, POSSIBLY REACHING
TROPICAL DEPRESSION STRENGTH WITHIN THE NEXT 24 HOURS AS THE LLC
TIGHTENS. DUE TO A 061221Z ASCAT METOP-B IMAGE, THE DISTURBANCE HAS
BEEN REPOSITIONED APPROXIMATELY 150NM SOUTHWEST. WHILE MODELS AGREE
ON THE OVERALL TRACK PHILOSOPHY, THERE IS SOME DISAGREEMENT ON WHEN
90W WILL TURN TO THE NORTHEAST. 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.

This has not been named by the official RSMC. Should not be called Domeng as Pagasa is not the official RSMC

00Z GFS down to 944 mb.

[euro6208]

Large monsoon circulation. Usually takes time for systems this large to consolidate.
