According to the Jiangsu Meteorological Observatory, the region south of the Huaihe River is bracing for a significant precipitation event over the next three days. Driven by moisture transport from the edge of the subtropical high, the incoming system is expected to bring heavy rain, localized downpours, and severe convective weather, including thunderstorms and strong winds, to the area.
What to expect in the coming days
The province is entering a period of unstable weather as a series of rain systems moves from south to north. From July 2 to July 5, the region south of the Huaihe River will experience persistent, heavy rainfall. The Jiangsu Meteorological Observatory reports that areas along the Yangtze River and the region between the Yangtze and Huaihe rivers will be particularly affected, with some locations seeing heavy to torrential rain.
The weather will arrive with sharp, sudden intensity. Thunderstorms accompanied by short-term heavy precipitation and wind gusts reaching 7 to 9 on the Beaufort scale are possible throughout the impacted areas. By July 5, some parts of the region could see localized heavy rainfall persist as the system continues its path.
The current weather pattern is part of a larger, month-long trend. Since the beginning of June, southern China has faced multiple rounds of intense storms, with some monitoring stations recording rainfall totals more than double their historical averages for the same period.
Temperature shifts and relief from the heat
The arrival of this rain system marks a change in the province’s recent stifling heat. Before the rain moved in, temperatures across most of Jiangsu climbed to between 30℃ and 34℃, creating a humid and oppressive environment. As the rain system moves across the province, forecasters expect a noticeable drop in temperatures.
Over the next five days, maximum temperatures in most cities are expected to retreat to the 26℃ to 29℃ range. This shift will provide a significant reprieve from the current humidity. While the northern parts of the province may still see highs reaching 34℃ to 35℃ in the short term, the trend across the region is toward a cooler, albeit wetter, period.
The primary challenge here is the combination of high-intensity, short-duration rainfall and rising water levels in rivers and lakes across the Su-Nan and Jiang-Huai regions. Because the ground is already saturated from earlier rains, the capacity for drainage is limited. The risk is not just the rain itself, but the secondary impact on infrastructure and the potential for flash flooding in low-lying areas.
Safety precautions for residents
Authorities have issued warnings for residents to prepare for the adverse weather. Given the potential for reduced visibility and slippery road conditions, drivers are advised to exercise caution and avoid low-lying areas that may flood quickly. Outdoor workers should prioritize finding shelter in sturdy buildings and stay clear of vulnerable structures like billboards, utility poles, and large trees that could be toppled by high wind gusts.
For the agricultural sector, the focus is on water management. Farmers have been advised to clear ditches and ensure proper drainage in fields to prevent waterlogging, which could otherwise damage crops after several days of sustained rainfall.
Frequently Asked Questions
Which regions in Jiangsu will be most affected by the upcoming rain?
The Jiangsu Meteorological Observatory states that the area south of the Huaihe River, particularly the regions along the Yangtze River and between the Yangtze and Huaihe rivers, will experience the most significant precipitation.
Will the heatwave continue during this rainy period?
No, the heat will subside. Temperatures are expected to drop, with most cities seeing highs fall to between 26℃ and 29℃ over the next five days, providing relief from the current humid conditions.
What specific dangers should the public watch for?
The main risks include short-term heavy precipitation, thunderstorms, and wind gusts of 7 to 9. These conditions can cause sudden flooding, slippery roads, and potential damage to outdoor structures or trees.
