Forecasters say the poorly defined system dissipated while interacting with the Southeast Asia land mass.
It was initially thought the depression would strengthen into Tropical Storm Bopha within the next week and pass over the northern Malay Peninsula, along the Thai-Myanmar border.
Meteorologists said they were monitoring the system for regeneration, possibly over the Gulf of Thailand.
Tropical systems have historically been exceedingly rare in that part of the world.
