Group 1 - A significant rain belt along the Yangtze River has caused frequent rainfall in the Sichuan-Chongqing and Jiangsu-Anhui regions, with rainfall intensity varying greatly and localized heavy downpours observed [1] - Monitoring data indicates that from the 9th, areas in eastern Sichuan, Chongqing, and Hubei experienced rainfall between 50 to 100 millimeters, with localized areas in Chengdu and Deyang reaching 253 to 349 millimeters [1] - Meteorological experts predict that from the 11th to the 12th, the rain belt will persist, with parts of Sichuan, Chongqing, northern Guizhou, northern Yunnan, Hubei, northern Hunan, Anhui, and Jiangsu expected to experience heavy to extremely heavy rainfall [1] Group 2 - Different types of rainfall can trigger geological disasters, with short-duration heavy rainfall leading to rapid surface runoff that can cause mudslides and shallow landslides due to soil saturation [2] - Continuous rainfall allows water to seep into deeper soil layers, increasing the weight of the rock and soil, which can lead to deep landslides when the friction between layers is weakened [2] - The risk of landslides does not cease immediately after rainfall, as water continues to infiltrate the soil, potentially leading to landslides days after the rain has stopped [2]

Group 1 - The core viewpoint of the article emphasizes the rapid and dangerous nature of mountain floods, particularly triggered by short-duration heavy rainfall events [1][3] - Short-duration heavy rainfall is defined as precipitation that significantly exceeds normal levels in a very short time, such as over 20 millimeters in one hour, often associated with severe weather phenomena like thunderstorms and hail [3] - The mountainous terrain exacerbates the risk of flooding due to its funnel-like structure, which allows rainwater to flow rapidly downhill, unlike flat plains that provide more space for water absorption and slow flow [5] Group 2 - Soil saturation plays a critical role in the formation of mountain floods; after continuous rainfall, the upper soil layers become saturated and lose their ability to absorb additional water, leading to surface runoff [7] - Healthy vegetation can intercept 10% to 30% of rainfall and slow down surface runoff, but human activities like deforestation can damage this ecological barrier, increasing the speed of water flow and the risk of secondary disasters like mudslides [9] - During flood events, immediate evacuation to higher ground is crucial if signs of flooding are observed, such as loud noises from upstream or rapidly rising water levels [11] Group 3 - Precautionary measures during flood season include avoiding camping, fishing, or driving through flooded areas, and staying informed about flood warnings from meteorological and natural resource departments [13] - Residents in flood-prone areas should familiarize themselves with evacuation routes and prepare emergency supplies, emphasizing the importance of early evacuation [13]

Core Viewpoint - The article emphasizes the importance of understanding the characteristics and warning signs of mountain floods and landslides, as well as the necessary safety measures to take in case of such natural disasters [1][4][9]. Group 1: Mountain Floods - Mountain floods are sudden and characterized by concentrated water flow, high speed, and strong destructive power, often occurring in low-lying areas near mountain streams [2]. - Warning signs of mountain floods include hearing a rumbling sound similar to a train, which may indicate upstream flooding, and a sudden change in water clarity from clear to muddy [4]. - In the event of a mountain flood, individuals should quickly move to higher ground, avoid fleeing downstream, and seek help from emergency services if surrounded by water [8]. Group 2: Landslides - Landslides occur when soil or rock layers slide down a slope due to factors such as river erosion, rainfall, earthquakes, or human activities [9]. - Warning signs of landslides include unusual sounds, cracks in the ground, and changes in vegetation [10]. - If caught in a landslide, individuals should hold onto sturdy objects, seek shelter under solid structures, and avoid entering the disaster area immediately after the event [12][13]. Group 3: Driving Safety - During rainy conditions, it is advised not to park near loose soil slopes or hazardous areas, and to drive cautiously on outer edges of roads to avoid landslide risks [15]. - If a vehicle encounters a landslide, drivers should turn back or find alternative routes, and if trapped in a tunnel, they should park safely and activate emergency lights [15]. Group 4: General Safety Tips - It is crucial to stay updated on weather forecasts and mountain flood warnings, and to avoid mountainous areas during heavy rain [18]. - Individuals in mountainous regions should keep a safe distance from riverbanks and be aware of hazard signs and evacuation routes [18].

Summary of Key Points Core Viewpoint - The province is expected to experience intermittent rainfall from July 2 to July 8, with significant rainfall and potential severe weather events such as thunderstorms, strong winds, and hail due to the influence of subtropical high pressure and upper-level troughs [1][2]. Group 1: Weather Impact - The rainfall in northern Shaanxi is expected to be prolonged, while western and northwestern Guanzhong will experience intense rainfall, leading to high cumulative precipitation and short-duration heavy rain [1]. - There is a high risk of secondary disasters such as mountain floods, geological hazards, and urban flooding due to the heavy rainfall, particularly in northern Shaanxi where some small and medium rivers are nearing warning levels [1]. - High temperatures in eastern Guanzhong and eastern Ankang may trigger localized severe convective weather, including thunderstorms and hail [1]. Group 2: Agricultural Recommendations - Agricultural experts recommend timely irrigation in areas like southern Xianyang, northern Xi'an, and Weinan, where soil moisture is lacking, and to implement measures such as spraying and shading in kiwi and grape planting areas to prevent sunburn from high temperatures [1]. - Farmers in northern Shaanxi and western Guanzhong should clear drainage ditches in advance to mitigate the adverse effects of water accumulation on crops and enhance pest monitoring and control [1]. - In apple and kiwi production areas in northern Shaanxi and western Guanzhong, precautions should be taken against wind and hail damage to branches and fruits [1]. Group 3: Transportation and Tourism - The rainfall is causing slippery conditions on roads and railways in northern Shaanxi, western and northwestern Guanzhong, with specific highways and rail lines experiencing significant rainfall and high risks of secondary disasters affecting transportation safety [2]. - With the increase in tourists during the summer, local tourism departments are advised to monitor weather forecasts and warnings to mitigate the adverse impacts of severe weather on tourist attractions and outdoor facilities [2].
