   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:
      (1) AT 21JAN26 0600Z, TROPICAL CYCLONE 15S (EWETSE) WAS LOCATED 
NEAR 24.3S 43.4E, APPROXIMATELY 217 NM SOUTHEAST OF EUROPA ISLAND, 
AND HAD TRACKED EAST-NORTHEASTWARD AT 07 KNOTS OVER THE PAST SIX 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 45 KNOTS 
GUSTING TO 55 KNOTS. SEE REF A (WTXS32 PGTW 211500) FOR FOR THE FINAL 
WARNING ON THIS SYSTEM.
      (3) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION (INVEST 91S) HAS PERSISTED NEAR 10.5S 
116.8E, APPROXIMATELY 549 NM NORTHWEST OF BROOME, AUSTRALIA. ANIMATED 
MULTISPECTRAL SATELLITE IMAGERY DEPICTS AN OBSCURED LOW LEVEL 
CIRCULATION CENTER WITH DEFINED CONVECTIVE BANDING ALONG THE WESTERN 
SEMICIRCLE. ENVIRONMENTAL ANALYSIS REVEALS A HIGHLY FAVORABLE 
ENVIRONMENT FOR DEVELOPMENT WITH STRONG WESTWARD UPPER-LEVEL OUTFLOW, 
LOW VERTICAL WIND SHEAR (10 TO 15 KTS), AND VERY WARM SEA SURFACE 
TEMPERATURES (29 TO 30 C). GLOBAL MODELS AGREE ON 91S TRACKING 
SOUTHEASTWARD AS IT CONTINUES TO DEVELOP OVER THE NEXT 24 TO 48 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 23 TO 28 
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1003 MB. 
THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE 
WITHIN THE NEXT 24 HOURS IS MEDIUM.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
