 As a result, the disturbance was introduced into the National Hurricane Center (NHC)'s 48-hour Tropical Weather Outlook with a low chance of tropical development.These chances were subsequently raised as further development occurred, with the system receiving a medium chance of development early on October 10, and a high chance of development as it approached the southern Leeward Islands late the following evening.As the wave crossed into the eastern Caribbean Sea and slowed down, the previously broad and open surface low consolidated and became stacked with the mid-level center.
