In MFR syntheses, it reaches 99.5%, both suggesting a high potential for retention.

The MFR named it Tropical Depression H4, estimating peak 10-minute winds of 55 km/h (35 km/h).
Early on March 4, convection increased and organized around the center of circulation, and the MFR classified it as Tropical Depression Twelve, about 270 km (170 mi) southwest of the Agalega Islands.
Due to the shear, the convection gradually diminished, prompting the MFR to downgrade it to a tropical disturbance on October 7.
