 Convective organization rapidly increased as it turned to the northwest, and the system developed into Tropical Depression Three on August 1 while located about 235 miles (375 km) east-southeast of Barbuda.Forecasters initially predicted wind shear from an upper level low would prevent strengthening and cause dissipation within three days.However, the depression continued to organize as deep convection continued to develop near the circulation despite moderate amounts of wind shear, and the system intensified into Tropical Storm Chris six hours after developing.
