Rare Four-Typhoon Pattern Braces East China as Super Typhoon Sadel Intensifies
SingTao · 1 SOURCESabout 2 hours ago2 MIN
Summary
Four tropical cyclones are simultaneously active over the Northwest Pacific and South China Sea in what meteorologists describe as an extremely rare "four-cyclone dance" event. According to monitoring by mainland weather authorities and the Hong Kong Observatory, the four systems are Super Typhoon Sadel, Tropical Storm Zitan, Tropical Storm Jianlavei, and a tropical depression near Yap Island. Sadel, viewed as a leading candidate for this year's most powerful typhoon, has developed a distinct eye and is now aimed directly at the East China coast. Meanwhile, Zitan combined with the southwest monsoon continues to hammer southern China, triggering severe flooding in Guangxi that has put at least 13 rivers above flood warning levels. The Hong Kong Observatory indicated it is closely monitoring the developments and assessing whether to issue tropical cyclone warning signals on Tuesday or Wednesday.
Key Points
- Typhoon Sadel, the 18th named storm this year, intensified two categories within 24 hours to super typhoon status, with maximum sustained winds of 52 meters per second
- Sadel's circulation spans approximately 1,000 kilometers in diameter with a highly symmetric structure and clear eye visible on satellite imagery
- The storm is moving west-northwest at 25 to 30 kilometers per hour and is expected to approach the East China Sea around October 26 before making landfall in Fujian or Zhejiang provinces
- Taiwan's weather bureau has predicted a possible maritime typhoon warning for Wednesday based on current forecast models
- Typhoon Zitan, the 19th named storm, is forecast to turn northeast and intensify to severe tropical storm or typhoon level as it approaches the Leizhou Peninsula and western Guangdong coast
Why It Matters
This rare convergence of four tropical cyclones simultaneously active creates compounding risks for coastal communities across East and South China. The overlapping wind and rain impacts from multiple systems will stress emergency response capabilities and infrastructure that would typically handle one storm at a time. Hong Kong residents planning travel to mainland China this week face elevated risks of flash floods, landslides, and urban waterlogging as successive systems sweep through the region.
