本周降雨又降温 注意安全出行和添衣保暖

Summary of Key Points Core Viewpoint - A new round of rainfall is expected in the province from September 15 to 16, influenced by the interaction of warm moist air from the West Pacific subtropical high and descending cold air, with overlapping rainfall areas from previous heavy rain events [1][2]. Weather Forecast - The provincial meteorological station predicts showers or thunderstorms across most areas during September 15 to 16, with northern regions experiencing moderate to heavy rain and localized areas in the southwest and central-east facing heavy rain [1]. - The maximum hourly rainfall intensity is expected to range between 20 mm to 40 mm, with some areas potentially reaching 50 mm to 70 mm [1]. - Cumulative rainfall is forecasted to be 20 mm to 40 mm in most areas north of the Huai River, while some counties in the southwest and central-east may see 50 mm to 80 mm, and specific locations in Nanyang and Shangqiu could reach 100 mm to 120 mm [1]. Temperature Changes - Cold air will lead to a noticeable drop in temperatures across the province, with a decrease of 4°C to 6°C expected on September 17, and many areas in the central-west likely to see maximum temperatures below 20°C [2]. - In the western regions, some areas may experience maximum temperatures below 15°C, with minimum temperatures around 10°C, and specific locations like Sanmenxia may see single-digit minimum temperatures [2]. Risk Management - Due to the overlap of this rainfall with previous heavy rain areas, multiple risks need to be addressed, particularly in agriculture, where monitoring of rainfall and soil conditions is crucial for managing late-stage crop growth and pest control [2]. - There are also concerns regarding geological and urban safety, as heavy rainfall may trigger flash floods, geological disasters, and urban flooding, necessitating preparedness for potential impacts on transportation, tourism, and construction sites [2].
