Chantal then swept through the Windward Islands on July 9, 2013 with heavy rainfall and gusty winds. Wind gusts from 50-55 mph were measured in St. Lucia and a peak gust to 78 mph was measured in Martinique.

As the storm moved briskly into the eastern Caribbean, it struggled to remain intact due to strong winds in the upper atmosphere.

On the afternoon of July 10, 2013, a Hurricane Hunter aircraft investigating Chantal found that the system no longer had low-level circulation center and that it had degenerated into a tropical wave (elongated area of low pressure). As a result, the National Hurricane Center issued its final advisory for Chantal at 5 p.m. on July 10, 2013. Though Chantal was no longer officially a tropical storm, it continued to dump heavy rainfall over Hispaniola at that time.
