Discussion: The upper-level shear axis is directly across the tropical North Atlantic basin suppressing tropical wave development (Fig. 1). Scattered thunderstorms are indicated in parts of the deep tropics and east of Florida. The daily North Atlantic basin SSTA analysis is mixed with a large subtropical marine heatwave (MHW) east of Florida and a large North Atlantic warm hole (NAWH) south of Greenland extending southwestward to the Northeast Coast (Fig. 2).
