Tropical Storm Activity: South Indian Ocean (16 January 2013)

No Active Tropical Warnings in the Northwest Pacific, North Indian Ocean, Central Pacific, Eastern Pacific, or Southern Hemisphere

There are no active tropical warnings in the Northwest Pacific/North Indian Ocean, Central/Eastern Pacific, or Southern Hemisphere at this time.

AN AREA OF CONVECTION (THE REMNANTS OF TC 09S) HAS 
PERSISTED NEAR 15.2S 74.9E, APPROXIMATELY 490 NM SOUTH-SOUTHEAST OF 
DIEGO GARCIA. ANIMATED MULTISPECTRAL SATELLITE IMAGERY REVEALS A 
POORLY DEFINED AND WEAK LOW LEVEL CIRCULATION CENTER WITH FLARING 
CONVECTION ASSOCIATED WITH THE REMNANTS OF TC 09S. A 171506Z SSMIS 
MICROWAVE IMAGE SHOWS A DISORGANIZED AND ELONGATED AREA WITH LIMITED 
CONVECTION IN THE SOUTHERN CONVERGENT AREA. THE SSMIS WIND PRODUCT 
SHOWS WEAK (05-10 KNOT) WINDS OVER THE NORTHERN PORTION OF THE AREA 
AND 20 TO 25 KNOT WINDS OVER THE SOUTHERN HALF WHICH IS BEING 
ENHANCED DUE TO THE SUBTROPICAL HIGH TO THE SOUTH. UPPER LEVEL 
ANALYSIS REVEALS MODERATE VERTICAL WIND SHEAR (10-20 KNOTS) WITH 
LITTLE TO NO OUTFLOW. SEA SURFACE TEMPERATURES IN THE AREA ARE 
MARGINALLY FAVORABLE FOR DEVELOPMENT (26 TO 27 DEGREES CELSIUS). 
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 KNOTS. 
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1003 MB. DUE TO 
THE MARGINAL ENVIRONMENTAL CONDITIONS, THE POTENTIAL FOR 
REDEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 
HOURS IS LOW.
