HK01 · 1 SOURCESabout 4 hours ago2 MIN

Summary
The Hong Kong Observatory announced on Wednesday that a tropical depression has formed near Yap Island and is expected to develop into Severe Typhoon Surigae by Sunday, September 27. Although the storm is not anticipated to strike Hong Kong directly, its outer descending airflow will envelop Guangdong in intense heat, pushing temperatures in Hong Kong to 34 degrees on multiple days from Saturday through Wednesday. The system's trajectory remains highly uncertain—forecasts suggest it could curve northward toward Japan or cross Taiwan and approach the eastern Guangdong coastline. This comes as the city prepares for the Mid-Autumn Festival on Friday and the National Day holiday on October 1, when a fireworks display is scheduled for Victoria Harbour.
Key Points
- A tropical depression formed early Wednesday morning approximately 2,690 kilometres east-southeast of Hong Kong, with maximum sustained winds of 45 km/h
- The system is forecast to intensify into Tropical Storm Surigae on Thursday, Severe Tropical Storm on Friday, Typhoon on Saturday, and Severe Typhoon by Sunday with winds reaching 175 km/h
- Five-day heat wave predicted: Saturday through Wednesday will see sunny, sweltering conditions with temperatures ranging from 33 to 34 degrees in urban areas
- Northeast monsoon arriving October 1 will bring cloud cover and scattered showers, potentially disrupting the National Day fireworks display over Victoria Harbour
- Taiwan's Central Weather Administration and Japan's Meteorological Agency projections align with the Observatory's forecasts, both predicting a northward turn affecting the Ryukyu Islands
Why It Matters
The approaching typhoon and subsequent heat wave will test Hong Kong's emergency preparedness and public health systems during a culturally significant period. For residents planning outdoor Mid-Autumn Festival gatherings or National Day celebrations, the contrasting forecasts—extreme heat followed by cooler, showery weather—will require careful scheduling. The uncertainty surrounding the typhoon's final trajectory also highlights the inherent limitations of medium-range tropical cyclone forecasting, underscoring the importance of continued monitoring as the system approaches the region next week .
