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: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 95S) PREVIOUSLY LOCATED NEAR 
31.3S 50.5E IS NOW LOCATED NEAR 31.4S 50.2E, APPROXIMATELY 684 NM SOUTH-
SOUTHWEST OF LA REUNION. THE SYSTEM IS CURRENTLY CLASSIFIED AS A 
SUBTROPICAL CYCLONE, GENERALLY CHARACTERIZED AS HAVING BOTH TROPICAL AND 
MIDLATITUDE CYCLONE FEATURES. ANIMATED MULTISPECTRAL SATELLITE IMAGERY 
(MSI) DEPICTS AN ELONGATED LOW LEVEL CIRCULATION CENTER (LLCC). THIS 
SYSTEM HAS A LOW CHANCE OF BECOMING A TROPICAL CYCLONE, AND THE SYSTEM 
IS REMAINING QUASI-STATIONARY DUE TO THE POLAR FRONT JET (PFJ) BEING 
SPLIT ON THE NORTHERN AND SOUTHERN SIDES OF THE SYSTEM. INVEST 95S IS IN 
A HIGHLY UNFAVORABLE ENVIRONMENT WITH MODERATE VERTICAL WIND SHEAR (20+ 
KTS) AND COLD SEA SURFACE TEMPERATURES (SST) OF 22-23C, OFFSET BY GOOD 
POLEWARD OUTFLOW. ALL GLOBAL DETERMINISTIC AND ENSEMBLE MODELS DEPICT A 
QUASI-STATIONARY TRACK THROUGHOUT THE SYSTEMS LIFESPAN BEFORE BEING 
OVERTAKEN BY VERTICAL WIND SHEAR FROM THE PFJ. FOR HAZARDS AND WARNINGS, 
REFERENCE THE FLEET WEATHER CENTER SAN DIEGO HIGH WINDS AND SEAS PRODUCT 
OR REFER TO LOCAL WMO DESIGNATED FORECAST AUTHORITY. MAXIMUM SUSTAINED 
SURFACE WINDS ARE ESTIMATED AT 33 TO 38 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 
REMAINS LOW.
      (2) NO OTHER SUBTROPICAL SYSTEMS.//
