SATELLITE IMAGERY(MSI) DEPICTS FLARING CONVECTION WRAPPING INTO A
SLOWLY CONSOLIDATING LLC. ENVIRONMENTAL ANALYSIS INDICATES GENERALLY
FAVORABLE CONDITIONS FOR DEVELOPMENT, WITH EQUATORWARD OUTFLOW, LOW
(10-15 KTS) VERTICAL WIND SHEAR (VWS) AND WARM (29-30 C) SEA SURFACE
TEMPERATURES (SST). NUMERICAL MODELS ARE IN GOOD AGREEMENT THAT
