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 98S) PREVIOUSLY LOCATED NEAR 
17.7S 175.5W IS NOW LOCATED NEAR 18.5S 172.2W, APPROXIMATELY 134 NM WEST-
NORTHWEST OF NIUE. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY DEPICTS 
DEEP CONVECTION CONSOLIDATING AROUND A LOW LEVEL CIRCULATION CENTER 
(LLCC) EMBEDDED IN THE SOUTHERN PACIFIC CONVERGENCE ZONE. A 100926Z 
SCATTEROMETRY PASS SHOWS A WIDE SWATH OF GALE FORCE NORTHWESTERLIES ON 
THE EASTERN FLANK OF THE CIRCULATION WITH DEEP CONVECTION ESTABLISHING 
ITSELF OVER ALL QUADRANTS. THE ENVIRONMENTAL ANALYSIS REVEALS THAT THE 
SYSTEM EXISTS UNDER A NARROW ALLEY OF LOW VERTICAL WINDSHEAR (5-15KTS) 
WITH VIGOROUS POLEWARD OUTFLOW.  SEA SURFACE TEMPERATURES ARE 28-29 
DEGREES AND WILL REMAIN FAVORABLE UNTIL THE SYSTEM REACH 22S LATITUDE, 
WHICH IS WHERE THE TEMPERATURES BEGIN TO DROP, AND NOT BE CONDUCTIVE FOR 
TROPICAL DEVELOPMENT. THE GLOBAL MODELS SHOWS A VERTICAL STACK 
CIRCULATION THAT WILL CONTINUE TO DEVELOP OVER THE NEXT 24 HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 30 TO 35 KNOTS. MINIMUM SEA 
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 991 MB. THE POTENTIAL FOR THE 
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS 
UPGRADED TO HIGH.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA. 2.B.(1) TO HIGH.//
