The Gansu Meteorological Administration upgraded the emergency response level IV for major meteorological support to level III at 15:30 on the 30th. The reporter learned from the Gansu Meteorological Administration that from 8:00 to 14:00 on the 30th, precipitation occurred in central Hexi and parts of Hedong in Gansu Province. Among them, torrential rain occurred in southeastern Longnan City and central Pingliang City. Longnan City, Pingliang City, Linxia Hui Autonomous Prefecture, and Qingyang City experienced a total of 15 short-term heavy precipitation with precipitation greater than 20 mm per hour, with a maximum hourly rainfall of 41.8 mm. The Gansu Meteorological Observatory predicts heavy rain from July 30 to August 1 in eastern and southern Longnan City, southeastern Tianshui City, and central Pingliang City. The maximum cumulative rainfall is 140 to 180 mm, with a maximum cumulative rainfall of 140 to 180 mm, and up to 200 mm or more in some places. The Gansu Meteorological Administration suggests that this round of heavy precipitation has characteristics such as strong convection, strong hourly rain, long duration, and high cumulative rainfall, and is superimposed on early precipitation areas, causing a high risk of secondary disasters such as small and medium-sized river floods, flash floods, geological disasters, and urban and rural flooding. All regions need to take precautions.
