1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 26AUG26 0000Z, TYPHOON 17W (SAUDEL) WAS LOCATED NEAR 
27.8N 127.3E, APPROXIMATELY 82 NM NORTH- NORTHWEST OF KADENA AB, AND 
HAD TRACKED WEST-NORTHWESTWARD AT 08 KNOTS OVER THE PAST SIX HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 75 KNOTS GUSTING TO 
90 KNOTS. SEE REF A (WTPN31 PGTW 260300) FOR FURTHER DETAILS.
      (2) AT 25AUG26 1800Z, TROPICAL DEPRESSION 18W (NARRA) WAS 
LOCATED NEAR 20.0N 109.6E, APPROXIMATELY 216 NM EAST-SOUTHEAST OF 
HANOI, VIETNAM, AND HAD TRACKED NORTHEASTWARD AT 08 KNOTS OVER THE 
PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 25 
KNOTS GUSTING TO 35 KNOTS. SEE REF B (WTPN32 PGTW 252100) FOR THE 
FINAL WARNING ON THIS SYSTEM.
      (3) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 99W) PREVIOUSLY LOCATED NEAR 
15.3N 162.3E IS NOW LOCATED NEAR 16.0N 162.0E, APPROXIMATELY 330 NM 
SOUTHWEST OF WAKE ISLAND. ANIMATED ENHANCED INFRARED IMAGERY (EIR) 
DEPICTS DISORGANIZED BURSTS OF DEEP CONVECTION FULLY OBSCURING A 
LOOSELY DEFINED LOW-LEVEL CIRCULATION CENTER. THE 251441Z AMSR2 
WINDSPEED PRODUCT REVEALED A COMPACT, ASYMMETRIC, AND WEAK WIND FIELD, 
WITH 15-20 KT WINDS CONFINED TO BENEATH THE DEEP CONVECTION. THE 
251807Z SSMIS 91 GHZ DATA REVEALS FAINT LOW LEVEL CLOUD BANDING 
WRAPPING INTO THE CENTRAL DEEP CONVECTIVE PLUME. ENVIRONMENTAL 
ANALYSIS IS CONDUCIVE FOR DEVELOPMENT WITH LOW VERTICAL WIND SHEAR 
(10-15 KTS), WARM SEA SURFACE TEMPERATURES (29-30 C), ABUNDANT 
DEEPLAYER MOISTURE, AND STRONG POLEWARD OUTFLOW ALOFT. GLOBAL 
DETERMINISTIC AND ENSEMBLE MODELS ILLUSTRATE GRADUAL TO STEADY 
DEVELOPMENT OVER THE NEXT 24-36 HOURS AS THE SYSTEM TRANSITS GENERALLY 
NORTHWARD. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23 
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 HIGH. SEE REF C (WTPN21 PGTW 252330 COR) FOR 
FURTHER DETAILS.
      (2) NO OTHER SUSPECT AREAS.
   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: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//
