The Hainan Provincial Meteorological Bureau continued to issue level four rainstorm warnings and red warnings, and Qionghai, Wanning and other places announced the suspension of primary and secondary schools and kindergartens. Meteorological experts pointed out that this rainfall is a typical autumn rainstorm in Hainan, caused by the easterly jet stream affected by the combination of cold and warm air. The Department of Water Affairs and the Meteorological Bureau jointly issued a yellow flash flood meteorological risk warning to remind the public to guard against secondary disasters and provide safety avoidance guidelines.

The National Climate Center announced that the equatorial central and eastern Pacific Ocean has entered an El Niño state since May 2026.

The SST index in September was 2.94°C, and the eastern Pacific warm water center was more than 3.0°C higher. It is expected that sea temperatures will continue to rise in the next three months. This event may become the strongest El Niño since systematic monitoring.

Affected by heavy rainfall, Wanning City, Hainan Province raised the flood and wind prevention level IV emergency response to level II. All primary and secondary schools in the city were suspended for half a day, and kindergartens and off-campus training institutions were suspended for one day.
