Tropical Depression Nine (2025)

Storm Active: September 27-

Around September 16, the first of a pair of tropical waves entered the Atlantic basin from the east. Unlike its successor, which would become Hurricane Humberto, the leading wave did not generate much thunderstorm activity for much of its journey across the tropical Atlantic. It first attracted notice on September 21, when this activity increased markedly as it approached the Leeward Islands. The system remained too disorganized to consolidate into a tropical cyclone, but it brought significant rainfall across the Caribbean. It first impacted the Leewards on the 23rd, Puerto Rico the next day, and the Dominican Republic on the 25th. After that time, the disturbance slowed down and turned toward the north. Less land interaction and favorable atmospheric conditions allowed it to establish a circulation over the next couple of days. Eventually, the system was designated Tropical Depression Nine a little off the northern coast of east Cuba.

Despite achieving tropical cyclone status, the depression was very still broad and disorganized at first, with mid-level spin displaced from the low-level center. It began to build a dense area of convection near the developing center on the 28th.

As of 8:00am EDT on September 28, 2025, Tropical Depression Nine had maximum sustained winds of 35 mph, a minimum central pressure of 1002 mb, and was moving north-northwest at 7 mph. For more up-to-date information and the latest watches and warnings, please consult the National Hurricane Center.
