The wave traveled westward across the Atlantic Ocean, gradually organizing into a tropical depression on July 28, 2020. The depression strengthened into a tropical storm later that day, and the NHC assigned the name Isaias to the storm. Tropical Storm Isaias moved west-northwestward, passing through the Caribbean Sea and affecting several islands, including the Dominican Republic, Haiti, and the Bahamas.
