1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 90W) PREVIOUSLY LOCATED
NEAR 8.5N 136.8E IS NOW LOCATED NEAR 7.9N 136.4E, APPROXIMATELY 112
NM EAST-NORTHEAST OF PALAU. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
AND A 060421Z ATMS 165GHZ MICROWAVE IMAGE SHOW A POORLY ORGANIZED,
BROAD LOW LEVEL CIRCULATION WITH PERSISTENT, SCATTERED CONVECTION. A
RECENT PARTIAL ASCAT PASS REVEALS AN ELONGATED WIND FIELD WITH
SEVERAL 15-20 KNOT WINDS. UPPER LEVEL ANALYSIS SHOWS 90W BORDERING
AN AREA OF LOW TO MODERATE (10-25 KNOT) VERTICAL WIND SHEAR WITH
SUPPORTIVE OUTFLOW ALOFT. SEA SURFACE TEMPERATURES (30-31 CELSIUS)
IN THE REGION REMAIN CONDUCIVE FOR FUTURE DEVELOPMENT. DYNAMIC
MODELS AGREE ON A WESTWARD TRACK WITH MINIMAL INTENSIFICATION OVER
THE NEXT 36-48 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED
AT 12 TO 18 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 LOW.

 (2) THE AREA OF CONVECTION (INVEST 92W) PREVIOUSLY LOCATED
NEAR 2.9N 162.0E, IS NOW LOCATED NEAR 4.5N 161.2E, APPROXIMATELY 226
NM SOUTHEAST OF POHNPEI. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
SHOWS A LOW LEVEL CIRCULATION (LLC) WITH INTERMITTENT DEEP
CONVECTION OVERHEAD, OBSCURED BY A LARGE CIRRUS SHIELD. A 062305Z
METOP-B ASCAT PASS SHOWS AN ELONGATED CIRCULATION WITH AN AREA OF 15
TO 25 KNOT WINDS TO THE WEST. 92W IS IN A FAVORABLE ENVIRONMENT WITH
MARGINAL (15 TO 20 KNOT) VERTICAL WIND SHEAR OFFSET BY GOOD POLEWARD
OUTFLOW AND WARM (29 TO 30 CELSIUS) SEA SURFACE TEMPERATURE. GLOBAL
MODELS ARE IN GENERAL AGREEMENT THAT 92W WILL TRACK NORTHWESTWARD
AND INTENSIFY TO WARNING STATUS WITHIN 72 HOURS. 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 IS UPGRADED TO MEDIUM.
