Over the next 72-96 hours, the tropical depression will move west-southwest at about 20 km per hour and weaken into a low pressure area.
However, despite weakening, the storm's circulation is still very wide and dangerous, possibly causing strong winds, big waves and heavy rain for the Northern and North Central provinces, especially from September 25 and 26.
