What happened
On August 30 at 6 a.m., China's National Meteorological Center continued its yellow rainstorm warning and blue typhoon warning, covering the 24-hour period from 8 a.m. that day. The warnings affect broad areas across northern, eastern, central, and southern China.
Under the rainstorm warning, heavy to torrential rain is forecast in parts of Heilongjiang, Anhui, Jiangsu, Shanghai, Zhejiang, Jiangxi, Hunan, Guangxi, Guangdong, Hainan, Yunnan, and Taiwan. Some areas, including southern Anhui, central and southern Jiangsu, the southwestern Guangdong coast, and western Hainan, may see severe downpours, with localized extreme rainfall of 250-280 mm in parts of central and southern Jiangsu and western Hainan.
The typhoon warning concerns Tropical Depression Sadel, the remnant of this year's 18th typhoon. At 5 a.m., its center was located in Lianshan Zhuang and Yao Autonomous County, Qingyuan, Guangdong, with maximum winds of force 6 (12 m/s) and a minimum central pressure of 998 hPa. It is expected to move south-southwest at 15-20 km/h while gradually weakening.
Why it matters
The simultaneous rainstorm and typhoon warnings point to overlapping weather risks: a weakening tropical system interacting with widespread convective rainfall. This combination can produce very heavy rainfall, strong gusts, and localized severe convective weather, raising concerns for flooding, travel disruption, and safety in affected regions, particularly coastal and low-lying areas.
Key facts
Both a yellow rainstorm warning and a blue typhoon warning were in effect from 6 a.m. on August 30.
Localized extreme rainfall of 250-280 mm is possible in parts of central and southern Jiangsu and western Hainan from 8 a.m. August 30 to 8 a.m. August 31.

What to watch next
Attention should remain on the movement and weakening pace of Tropical Depression Sadel, as shifts in its track could alter rainfall distribution and wind impacts.
Authorities may adjust warning levels as the forecast evolves, so affected residents should monitor official updates on rainfall intensity and severe weather conditions.
