Note the area of haziness just east and southeast of the lobe of deep convection in the center of the satellite scene — this milky\/hazy appearance was due to the enhanced diffuse reflection of light off very rough seas (likely accompanied by abundant sea spray) resulting from a burst of strong surface winds across that particular area.
