RMKS/
1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   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:
      (1) THE AREA OF CONVECTION (INVEST 92P) PREVIOUSLY LOCATED 
NEAR 12.6S 155.4E IS NOW LOCATED NEAR 12.6S 155.4E, APPROXIMATELY 
384 NM NORTHEAST OF WILLIS ISLAND. ANIMATED MULTISPECTRAL SATELLITE 
IMAGERY, SUPPORTED BY A 080420Z GMI 89GHZ MICROWAVE IMAGE, REVEALS 
DISORGANIZED, FRAGMENTED CONVECTION SURROUNDING A PARTIALLY OBSCURE 
LOW LEVEL CIRCULATION (LLC) ELONGATED ALONG A NORTH-NORTHEAST TO 
SOUTH-SOUTHWEST AXIS. A 072247Z METOP-B ASCAT PASS REVEALS A VERY 
WEAK AND DISORGANIZED LLC WITH A LARGE AREA OF 15 KNOT WINDS 
WRAPPING AROUND THE NORTHERN PERIPHERY. INVEST 92P IS IN A FAVORABLE 
ENVIRONMENT FOR TROPICAL DEVELOPMENT WITH WARM (29-30C) SEA SURFACE 
TEMPERATURES, LOW (5-10KTS) VERTICAL WIND SHEAR (VWS), AND EXCELLENT 
POLEWARD OUTFLOW. GLOBAL MODELS ARE IN GOOD AGREEMENT THAT INVEST 
92P WILL CONSOLIDATE AS IT TRACKS TO THE SOUTHEAST, REMAINING 
LARGELY ASYMMETRIC, POTENTIALLY REACHING WARNING THRESHOLD IN THE 
NEXT SEVERAL DAYS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 
15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 
1004 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL 
CYCLONE WITHIN THE NEXT 24 HOURS REMAINS LOW.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//
