Later on October 14, the system became much better organized, with increasingly organized shower and thunderstorm activity, as conditions in the upper levels of the atmosphere became significantly more favorable. It was then that the National Hurricane Center first said that it was possible for a tropical depression to develop in the area. Dvorak classifications were initiated on October 15. The system continued to organize, with the National Hurricane Center remarking the system could ultimately become a hurricane. By late on October 15, the surface circulation became defined well-enough, with enough organized deep convection, for the National Hurricane Center to designate the system as "Tropical Depression Twenty-Four" while it was about 220 miles (345 km) east-southeast of Grand Cayman.
