 Interacting with the Intertropical Convergence Zone, a broad surface low pressure area developed within the area on May 27, and as it drifted northward the system maintained limited and disorganized convection.On May 29, convection increased and became concentrated near the low pressure center, and banding features developed in its eastern semicircle as the circulation became better defined.It is estimated the system formed into Tropical Depression Two-E at 1800 UTC on May 29 about 115 miles (185 km) southeast of Puerto Escondido, Oaxaca.
