A tropical wave is W of the Cabo Verde Islands, with an axis
extending from 03N30W to 17N30W, moving westward at 10 to 15 kt.
Saharan Air Layer (SAL) dry air and dust continue to affect the
wave environment, thus hindering convection at this time.

A tropical wave is in the E Caribbean with axis S of 20N along

upon by Saharan dry air and dust limiting convection to scattered
moderate and isolated thunderstorms N of 12N between 60W and 70W.

support scattered showers and tstms through early Friday.
