Since the beginning of July, Meiyu front has been wandering in the Yangtze River basin. Affected by it, Jiujiang City, Jiangxi Province experienced several rounds of heavy rainfall. The water levels in Jiujiang section of the Yangtze River, Xingzi Station of Poyang Lake and Yongxiu section of Xiuhe River exceeded the police in an all-round way, and the meteorological service in Jiujiang City entered a critical moment in flood season.
On the radar echo map, the long and narrow rain belt lingered over Jiujiang for a long time and refused to disperse. At 8 o’clock on the evening of July 7, the expected rainstorm hit unscrupulously, and a "tug-of-war" between meteorologists and heavy rain began nervously.
Half an hour later, the rain increased instead of decreasing, and the heavy rain was heavily slapped on the glass window of the duty room with lightning and thunder. "50 mm, the next 3 hours must be more than 100 mm! Please upgrade the orange warning in Hukou and Duchang, and continue to pay attention to preparing to upgrade the red warning. "
At 3: 30am on the 8th, Mei Ting, the forecaster of the Municipal Meteorological Observatory, was busy giving guidance to the county bureaus in the WeChat working group of Jiujiang Forecast, Early Warning and Joint Defense.
"Hukou issued a red rainstorm warning!" "Duchang issued a red rainstorm warning!" "Peng Ze issued a red rainstorm warning!" "Lushan issued a red rainstorm warning!" ….. At about 5 o’clock, the red rainstorm warning broke the silence of the city.
At 6: 50, the meteorological department of the city entered the second-level emergency response state. And this is only three or four days away from the three-level emergency response to the rainstorm at 11: 30 on July 5 and the four-level emergency response to the rainstorm at 8: 00 on July 4!
With the distribution of meteorological disaster prevention service materials for the deployment of heavy precipitation weather process to all member units, a series of early warning information was quickly transmitted to the mobile phones of flood control leaders and thousands of information officers, and a rainstorm information network was quickly spread among cities, towns and villages.
The relevant units moved when they heard of the flood. The Municipal Flood Control Office immediately started the preparations for mass transfer, the Municipal Disaster Reduction Committee successively started the early warning response of municipal disaster relief, the Municipal Transportation Bureau implemented traffic control at the important sections of the college entrance examination center, the Municipal Education Bureau issued an emergency notice of suspension of classes, and the municipal departments did a good job in investigating the hidden dangers of disaster-prone points in advance, clearing and dredging drainage ditches, and closely monitoring the hidden dangers of geological disasters … All departments in the city entered the state of emergency preparedness for storm prevention and took measures to deal with them calmly.
"Fortunately, I received the meteorological service information of the college entrance examination issued by the meteorological department, and prepared umbrellas, rain boots and spare clothes for my children. We also received the college entrance examination English listening forecast service from the Meteorological Observatory. Such a fine service is really intimate and must be praised! " A candidate’s parents left a message in the hotline column of Jiujiang traffic radio party style and political style.
"After receiving the early warning information from the Meteorological Bureau, we organized village cadres to rush to the village to start the persuasion and transfer of residents." Wang Fan, secretary of Nankeng Village, Jiangshang Township, Yongxiu County, said, "After the heavy rain, several houses built on the mountain were crushed by landslides, but there were no casualties due to timely evacuation."
As of July 9, Yunshan Reservoir in Yongxiu County increased the opening height of spillway gate to 220 cm, further increasing the discharge flow and ensuring the safety of flood season.
