1) AN AREA OF CONVECTION (INVEST 90S) HAS PERSISTED NEAR 9.9S
84.1E, APPROXIMATELY 700 NM EAST-SOUTHEAST OF DIEGO GARCIA.
ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND A 201324Z SSMIS 91GHZ
MICROWAVE IMAGE DEPICTS DEVELOPING CENTRAL CONVECTION AROUND A
POORLY DEFINED LOW LEVEL CIRCULATION CENTER (LLC). UPPER LEVEL
ANALYSIS INDICATES THE SYSTEM HAS ENTERED AN AREA OF MODERATE (15-
20 KTS) VERTICAL WIND SHEAR OFFSET BY DEVELOPING POLEWARD OUTFLOW
AND WARM (26-28C) SEA SURFACE TEMPERATURES (SSTS). NUMERIC WEATHER
PREDICTION MODELS ARE IN GOOD AGREEMENT 90S WILL TRACK WESTWARD AS
IT FURTHER DEVELOPS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED
AT 20 TO 30 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 MEDIUM.

Classifiable.

Hopefully an agency will notice.

This is like, what, a northern hemisphere TC in March?
