INVEST #93S
UPDATE
As of 18:00 UTC Dec 29, 2020:

B. TROPICAL DISTURBANCE SUMMARY:
THE AREA OF CONVECTION (INVEST 93S) PREVIOUSLY LOCATED NEAR
10.4S 90.0E IS NOW LOCATED NEAR 11.9S 86.5E, APPROXIMATELY 1130 KM WEST
OF COCOS ISLANDS. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY AND A
291551Z METOP-B 89GHZ SATELLITE IMAGE DEPICT DISORGANIZED BANDING
WRAPPING INTO A LOW LEVEL CIRCULATION CENTER (LLCC) WITH FLARING
CONVECTION IN THE WESTERN SEMI-CIRCLE. A 290204Z ASCAT-A IMAGE SHOWS A
WELL DEFINED CIRCULATION WITH MOSTLY 10 KNOT WINDS WITH 15-20 KNOT
WINDS IN THE SOUTHERN SEMICIRCLE. INVEST 93S IS IN A FAVORABLE
ENVIRONMENT FOR DEVELOPMENT WITH POLEWARD OUTFLOW ALOFT, MODERATE (15-
20 KTS) VERTICAL WIND SHEAR AND WARM (28-29C) SEA SURFACE
TEMPERATURES. GLOBAL MODELS ARE IN GENERAL AGREEMENT THAT INVEST 93S
WILL TRACK SOUTHWESTWARD AND INTENSIFY OVER THE NEXT 24 HOURS. MAXIMUM
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1007 MB. THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS
IS UPGRADED TO MEDIUM.

ENHANCED INFRARED SATELLITE IMAGERY AND A 291336Z SSMIS 91GHZ
SATELLITE IMAGE DEPICT DISORGANIZED BANDING WRAPPING INTO A POORLY
DEFINED LOW LEVEL CIRCULATION CENTER (LLCC) WITH FLARING CONVECTION IN
THE WESTERN AND NORTHERN SEMI-CIRCLES. INVEST 96S IS IN A MODERATELY
FAVORABLE ENVIRONMENT FOR DEVELOPMENT WITH WESTWARD AND POLEWARD
OUTFLOW ALOFT, STRONG TO MODERATE (20-25 KTS) VERTICAL WIND SHEAR AND
WARM (28-29C) SEA SURFACE TEMPERATURES. GLOBAL MODELS ARE IN GENERAL
AGREEMENT THAT INVEST 96S WILL SLOWLY TRACK SOUTHEASTWARD WITH LITTLE
INTENSIFICATION OVER THE NEXT 24 HOURS. MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1007 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO
LOW.
