Typhoon Kajiki Just Emerged — Will It Devastate Central Vietnam with 300 mm Rain and Fierce 167 km/h Gusts?

Typhoon Kajiki

A rapidly intensifying Typhoon Kajiki (also known as Isang) is now barreling toward central Vietnam, threatening catastrophic wind, rain, flooding, landslides, and surges. This forecast-driven article delivers a precise, fact-packed breakdown of what’s coming, when, and where—formatted for clarity.

Current Status & Forecast

Origin & Development

  • On August 20, 2025, a low-pressure area formed east of southeastern Luzon. It became a tropical depression named Isang by PAGASA on August 22, shortly after making landfall in Aurora province.
  • The system then entered the South China Sea, with favorable conditions—such as warm sea-surface temperatures and low wind shear—prompting the JMA to name it Kajiki on August 23.

Movement & Intensification

  • As of August 23 afternoon, Kajiki’s center lies roughly 300 km east-northeast of the Paracel (Hoang Sa) Islands, moving west-northwest at about 25 km/h. Gusts are reaching Level 14–15 on the Beaufort scale, equivalent to severe typhoon strength; sustained winds about Level 12.
  • The storm is forecast to intensify further—reaching Level 12 winds with gusts up to Level 15 by August 25, just before landfall between Thanh Hoa and Quang Tri.

Rainfall Forecast

  • Between August 24–26, heavy to torrential rains (150–300 mm, with localized areas exceeding 600 mm) are expected in Thanh Hoa, Nghe An, Ha Tinh, Quang Tri, raising serious flash and landslide risks.
  • Models also predict 350 mm inland and up to 400 mm offshore, with intense convection sustaining well into Vietnam and eastern Laos.

Storm Surge, Waves & Coastal Hazards

  • Coastal and sea conditions will be extreme: waves between 4–8 m, of 0.5–1.2 m, with sea levels possibly rising to 3.6 m at Sam Son, 3.8 m at Hon Ngu, and 2–2.8 m in other coastal points like Vung Ang and Cua Gianh. (VietNamNet News)
  • This poses grave dangers to maritime activities, low-lying communities, infrastructure, and port facilities.

Major Threats at a Glance

  1. Typhoon Kajiki -Force Winds
    – Sustained near 12 Beaufort; gusts up to Level 15 (~167 km/h) can cause structural damage.
  2. Catastrophic Rainfall & Flash Flooding
    – Rainfall surpassing 200 mm in just 3 hours risks flooding dams, rivers, and triggering landslides. Storm Surge & High Waves
    – Coastal flooding, potentially inundating cities and ports; marine conditions deadly. Secondary Hazards in Laos & North Vietnam
    – Heavy continuing rainfall may spark further flooding in northern Vietnam, including Hanoi, and mountainous regions of Laos.

Call to Action Typhoon Kajiki & Final Advice

Authorities and residents in Thanh Hoa, Nghe An, Ha Tinh, Quang Tri (and broader north-central Vietnam) must immediately prepare with evacuation plans, secure structures, and focus on mountainous zones prone to flash floods and landslides. Communities along the coast must heed warnings about storm surge, and maritime operations should cease.
