評級Low
(1) AN AREA OF CONVECTION (INVEST 91S) HAS PERSISTED NEAR
11.1S 72.5E, APPROXIMATELY 220 NM SOUTH OF DIEGO GARCIA. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY DEPICTS FLARING CONVECTION THAT HAS
STARTED TO BUILD BACK OVER THE PREVIOUSLY EXPOSED LOW LEVEL
CIRCULATION CENTER. A 280414 ASCAT PASS SHOWED A WELL DEFINED LLCC
WITH 20 TO 25 KNOT WINDS SURROUNDING THE CENTER. HOWEVER, THE
CURRENT ENVIRONMENT IS MARGINAL DUE TO PERSISTENT 25 TO 30 KNOT
EASTERLY VERTICAL WIND SHEAR THAT IS HINDERING CONVECTIVE
DEVELOPMENT. GLOBAL MODELS DO NOT SHOW ANY DEVELOPMENT OF THIS
SYSTEM AS IT REMAINS QUASI-STATIONARY IN THE HIGH SHEAR ENVIRONMENT
OVER THE NEXT FEW DAYS. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED
TO BE NEAR 1009 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.
