Typhoon Kajiki is starting to bring flooding rainfall, destructive winds and large waves to parts of Southeast Asia.
Kajiki is the 23rd tropical depression in the Pacific region in 2025, and the 14th to develop into at least a tropical storm this season. As of 10am local time on Sunday, August 24, 2025, Kajiki was located 180 nautical miles southeast of Hanoi, and moving west at about 20 km/h.
With optimally warm sea surface temperatures of 30 degrees, abundant moisture to keep it fuelled and no significant wind events to tear it down, Kajiki has been able to develop into a full-scale Typhoon. At its current speed and trajectory, Kajiki is expected to reach the shores of Vietnam on Monday afternoon.
Forecast rainfall associated with this system as well as its maximum winds are expected over the waters of the South China Sea as well as Vietnam’s northern coast before landfall. Sustained winds up to 150km/h are expected, gusting up to 185km/h, whilst accumulated rainfall from now to the system’s landfall during Monday afternoon or early evening could reach 400mm offshore and up to 350mm in Vietnam and eastern Laos.

While the system looks to breakdown quickly after it makes landfall, heavy rainfall associated with its remnants will persist over Southeast Asia till mid-next week. The rest of the moisture is swept up into the Indian Monsoon, adding to the heavy rainfall and storms over the region with a monsoon burst.
