SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE INDIAN OCEAN 
REISSUED/100600Z-101800ZJAN2026//
RMKS/
1. NORTH INDIAN OCEAN AREA (MALAY PENINSULA WEST TO COAST OF AFRICA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 90B) PREVIOUSLY LOCATED NEAR 
8.0N 82.8E IS NOW LOCATED NEAR 9.3N 81.0E, APPROXIMATELY 230 NM SOUTH 
OF CHENNAI, INDIA. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS A 
WELL-DEFINED EXPOSED LOW LEVEL CIRCULATION CENTER (LLCC) JUST OFF THE 
COAST OF SRI LANKA. ENVIRONMENTAL ANALYSIS REVEALS AN UNFAVORABLE 
ENVIRONMENT FOR DEVELOPMENT DUE TO TERRAIN INTERACTION, MODERATE TO 
HIGH VERTICAL WIND SHEAR (20 TO 25 KTS), MODERATE UPPER-LEVEL 
OUTFLOW, AND WARM SEA SURFACE TEMPERATURES OF (27 TO 28 C). 
DETERMINISTIC MODELS AGREE ON LITTLE TO NO FURTHER DEVELOPMENT OF 90B 
AS IT BEGINS TO INTERACT WITH SRI LANKA AND SOUTHERN INDIA. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 23 TO 28 KNOTS. MINIMUM SEA 
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1008 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.
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 93S) PREVIOUSLY LOCATED NEAR 
12.0S 76.1E IS NOW LOCATED NEAR 12.7S 76.2E, APPROXIMATELY 390 NM 
SOUTHEAST OF DIEGO GARCIA. ANIMATED MULTISPECTRAL SATELLITE IMAGERY 
AND A 100031Z SSMIS 91 GHZ MICROWAVE IMAGE DEPICT A CONSOLIDATING LOW 
LEVEL CIRCULATION CENTER (LLCC) WITH PERSISTENT DEEP CONVECTION OVER 
THE SOUTHWESTERN PERIPHERY. ENVIRONMENTAL ANALYSIS DEPICTS A 
FAVORABLE ENVIRONMENT FOR DEVELOPMENT WITH GOOD POLEWARD AND 
EQUATORWARD OUTFLOW ALOFT, LOW TO MODERATE VERTICAL WIND SHEAR (15 TO 
20 KTS), AND WARM SEA SURFACE TEMPERATURES (28 TO 29 C). GLOBAL 
MODELS AGREE ON 93S TRACKING GENERALLY SOUTHEAST AS IT CONTINUES TO 
CONSOLIDATE OVER THE NEXT 24 TO 48 HOURS. MAXIMUM SUSTAINED SURFACE 
WINDS ARE ESTIMATED AT 28 TO 33 KNOTS. MINIMUM SEA LEVEL PRESSURE IS 
ESTIMATED TO BE NEAR 1005 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.//
