Over the next 72 hours, the lingering vortex of Typhoon "Danas" will continue to induce heavy rainfall in the southern regions of Jiangnan and South China, with particularly intense downpours expected in Fujian and Guangdong. Residents in these areas are advised to take precautions against potential secondary disasters. Concurrently, while high temperatures in the Yangtze River's southern regions are expected to subside, sultry conditions will intensify in northern regions, including Shandong and Henan. The public in these areas should prioritize heatstroke prevention and stay hydrated.
