Vietnam is facing a significant threat from Typhoon Kajiki, with more than 586,000 residents ordered to evacuate ahead of its arrival. The storm, currently packing winds of 166km/h (103mph), is anticipated to gain strength as it approaches landfall early on Monday, according to weather forecasts. Affected areas include the central provinces of Thanh Hoa, Quang Tri, Hue, and Da Nang, where residents have been mandated to leave their homes for safety.

In light of the impending danger, numerous flights have been canceled, and boats in coastal regions have been instructed to remain ashore. Following severe weather conditions in Hainan, China, which are characterized by heavy rainfall of up to 320mm (12.6 inches), the region braces for the storm's passage while it continues to escalate.

The BBC Weather department has indicated that as Typhoon Kajiki moves inland into Vietnam, it is expected to lose some intensity, yet still poses considerable threats with winds reaching 200km/h and anticipated rainfall between 300-400mm. Storm surges could hit between 2-4m (6.6-13ft), heightening the risk for any exposed structures and vehicles.

Local authorities have advised residents within the storm's trajectory to avoid outdoor activities after 14:00 GMT on Sunday. The Vietnam Ministry of Agriculture and Environment has emphasized the extreme danger posed by the storm, cautioning against the risks to tourism and fishing operations. In preparation, Vietnam Airlines has canceled at least 22 flights to and from the central cities scheduled for Sunday and Monday. Concerns are heightened as the storm has the potential to mirror the devastating impacts of Typhoon Yagi from last September, which resulted in significant loss of life.

The region remains on high alert as officials coordinate response efforts and provide necessary support to evacuated individuals amidst this natural disaster.
