周一（6月23日），"梅姑娘"带着暴脾气持续营业。午后雨势增大，在雨水打压下，气温"萎靡不 振"，杭州主城区最高温仅26.5℃，是夏日里难得的清爽。接下来，天气舞台还将开启一场雨水和高温 的"擂台赛"，你方唱罢我登场，精彩不断。 降水、高温轮番登场，这也是夏季"标配"天气。不过，天气舞台还有一个"捣蛋鬼"——台风，行踪 诡秘，带来很多不确定性。 1号台风"蝴蝶"刚走，2号台风便紧随其后。据中央气象台消息，今年第2号台风"圣帕"于周一8时在 距离日本东京南偏东方向约1330公里处生成强度等级为热带风暴，最大风力为8级，18米/秒。预 计，"圣帕"将以每小时25-30公里的速度向西北方向快速移动，强度变化不大，24日夜间开始转向偏北 方向移动，并向日本本州岛南部沿海靠近，强度逐渐减弱并将变性为温带气旋。 好在，今年的2号"圣帕"并未瞄准我国，可以暂时松一口气。"今年的2号台风圣帕未来北上奔赴日 本，对我国无影响。"中国天气网首席气象分析师信欣介绍，不过，根据数值预报，6月底-7月初，远海 上可能还有台风生成。"后期台风有可能赶上副热带高压北抬，导致路径可能在较高纬度西行，这个台 风存在奔向华东的可能性，目前尚不能 ...

Weather Conditions - The weather in Hangzhou has shifted from rainy to hot, with temperatures exceeding 35°C from Tuesday to Saturday, indicating a high-temperature phase [2][3] - The current weather pattern is described as "sunny and hot with localized afternoon thunderstorms," with a forecast of continuous rain returning after Saturday [3] Public Services - The Hangzhou urban management department has launched a "Summer Cooling" project, providing free cooling soup at city management stations for outdoor workers and citizens during the high temperatures [4] - A total of 73 city management stations are prepared with cooling supplies, offering various services such as rest areas, cooling drinks, and emergency medical supplies [4] Safety Concerns - Fire safety risks associated with high humidity and the use of electrical appliances have been highlighted, particularly regarding the improper use of extension cords and dehumidifiers [5][6] - Experiments conducted by the fire rescue team demonstrated that common household items can pose significant fire hazards in humid conditions, with temperatures reaching dangerous levels [5][6][7]

Core Viewpoint - A significant rainfall event is expected to impact multiple provinces in southern China, with the potential for severe weather conditions and secondary disasters due to the heavy rainfall [1][3][7]. Summary by Relevant Sections Rainfall Impact Areas - The core impact areas for the upcoming rainfall include nine provinces: Sichuan, Chongqing, Hubei, Hunan, Henan, Jiangsu, Anhui, Guizhou, and Guangxi [3][4]. - Rainfall is expected to be concentrated in regions such as southern Shaanxi, eastern Sichuan, western Hubei, and southeastern Henan, with potential for heavy rain from June 19 to 21 [3][6]. Rainfall Intensity and Duration - The rainfall process is characterized by a long duration and significant cumulative rainfall, with some areas receiving over 100 millimeters, and localized regions potentially reaching 200 to 300 millimeters [3][6]. - Compared to historical averages, the intensity of this rainfall event is expected to be stronger due to the influence of a strong subtropical high and cold air masses [4][6]. Weather Patterns and Causes - The formation of this rainfall is attributed to the interaction of warm and cold air masses, leading to sustained heavy rainfall across the Yangtze River basin [4][6]. - The subtropical high is expected to shift northward, facilitating the movement of warm, moist air into the affected regions [4][6]. Secondary Disaster Risks - There is a heightened risk of secondary disasters such as flash floods and geological hazards in areas with significant rainfall accumulation, particularly in eastern Guangxi, northern Hubei, and southwestern Hunan [7][9]. - The rainfall is also expected to alleviate drought conditions in several regions, including the Sichuan basin and parts of Henan, while still posing risks of rapid transitions from drought to flooding [7][9].

Group 1 - The rainy season in Zhejiang has seen a significant amount of rainfall, leading to high water levels in reservoirs and river networks, prompting the provincial water resources department to end the level IV emergency response for water and drought disaster prevention [2][3] - The upcoming weather forecast indicates a transition to a hot and dry pattern, with temperatures expected to rise sharply to between 35-37°C starting next week [2][3] - Typhoon "Butterfly" is approaching, expected to bring strong rainfall to the region, particularly affecting areas in southern China, with potential impacts on Zhejiang as the remnants of the typhoon move northeast [4][5][6] Group 2 - The current water levels in the Four Ridge Reservoir have reached a record high of 69.69 meters, exceeding the flood limit, leading to the initiation of controlled water discharge to manage reservoir capacity [3] - The typhoon's slow movement and the influx of monsoon winds may enhance rainfall intensity, with forecasts suggesting the possibility of heavy rain in northern Guangdong, Jiangxi, and Zhejiang [5][6] - Local water management authorities are advised to remain vigilant for potential flooding risks due to the expected heavy rainfall from the typhoon remnants [6]

Group 1 - The first typhoon of the year, "Butterfly," has formed in the South China Sea and is expected to make landfall in Hainan on Friday, bringing significant rainfall and strong winds [2][3] - "Butterfly" is predicted to strengthen to a strong tropical storm level (10-11 scale, 25-30 m/s) as it approaches the southern coast of Hainan [2] - After making landfall, "Butterfly" will move northeast, potentially affecting regions such as Jiangxi, Fujian, and Zhejiang with heavy rainfall due to the interaction of warm and cold air masses [2][3] Group 2 - The impact of "Butterfly" on Zhejiang is currently minimal, but the province may experience rain or thunderstorms due to the typhoon's outer cloud systems [3] - In Hangzhou, while the center of "Butterfly" will not directly affect the city, the peripheral effects could still lead to significant weather changes, necessitating close monitoring [3]

Group 1 - The first typhoon of the year, "Butterfly," formed on June 11, indicating the official start of the typhoon season, which is notably late this year compared to the average formation date of March 24 from 1991 to 2024, being over two months delayed [2][3] - "Butterfly" is currently classified as a tropical storm, with expectations of intensifying to a strong tropical storm or typhoon level (10-12 scale) due to favorable conditions such as high sea temperatures and moisture from the southwest monsoon [1][2] - The typhoon is projected to bring significant wind and rain impacts to Guangdong, with wind speeds reaching 7-10 levels in various coastal areas and heavy rainfall expected from June 13 to 15, marking the strongest precipitation event since the onset of the flood season [2][3] Group 2 - The delay in the typhoon season is attributed to a larger and stronger subtropical high-pressure system, which has suppressed the necessary convective development for typhoon formation, along with a southward shift in the tropical convergence zone and delayed summer monsoon onset [3]
