SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE INDIAN OCEAN 
REISSUED/170600Z-171800ZNOV2025//
RMKS/
1. NORTH INDIAN OCEAN AREA (MALAY PENINSULA WEST TO COAST OF AFRICA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
2. SOUTH INDIAN OCEAN AREA (135E WEST TO COAST OF AFRICA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 97S) PREVIOUSLY LOCATED NEAR 
11.0S 127.9E IS NOW LOCATED NEAR 11.0S 128.4E, APPROXIMATELY 174 NM 
WEST-NORTHWEST OF DARWIN. MULTISPECTRAL SATELLITE IMAGERY (MSI) 
DEPICTS A CONSOLIDATING LOW-LEVEL CIRCULATION CENTER (LLCC), WITH 
PERSISTENT DEEP CONVECTION OVER THE CENTER. A 162355Z ASCAT-B PASS 
SHOWS A SMALL INNER-CORE WITH STRONGER WINDS OF 20-25 KNOTS. 
ENVIRONMENTAL ANALYSIS REVEALS FAVORABLE CONDITIONS FOR DEVELOPMENT 
WITH LOW TO MODERATE VERTICAL WIND SHEAR (15-20 KNOTS), GOOD POLEWARD 
OUTFLOW ALOFT, AND WARM SEA SURFACE TEMPERATURES (30-31 C). GLOBAL 
MODELS ARE IN FAIR AGREEMENT THAT INVEST 97S WILL CONTINUE TO DEVELOP 
WITHIN THE NEXT 24-48 HOURS WITH A SLOW EAST-NORTHEASTWARD TRACK. 
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 23 TO 28 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.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 2.B.(1) TO 
MEDIUM//
