It was learned from the Municipal Flood Control and Drought Relief Headquarters that at 16: 50 yesterday, the Municipal Meteorological Observatory issued a blue rainstorm warning. According to the relevant provisions of the Emergency Plan for Flood Control and Drought Relief in Dalian and combined with the weather forecast, after consultation and judgment, the Municipal Flood Control and Drought Relief Headquarters decided to issue a blue flood control warning from 17: 00 yesterday and start the city's flood control level IV emergency response.

In order to do a good job in heavy rainfall prevention, the municipal defense index has made the latest arrangements. All types of flood control responsible persons at all levels are required to take up their posts before 19: 00 yesterday, and organize and implement various prevention and response work. Strengthen consultation and judgment, do a good job in targeting disaster early warning, extend the risk forecast period, and timely transmit early warning and forecast information to the forefront of the grassroots level.

The forecast rainfall highly coincides with the rainfall area on the night of July 1st. The soil water saturation in some rainfall areas is high, and some reservoirs are already operating at high water levels. If there is heavy rainfall again, it will easily lead to local river floods, mountain torrents, mudslides and other emergencies, which will seriously affect the safe operation of reservoirs and people's lives. All regions and relevant departments should pay close attention to rainfall information and take targeted preventive measures.

Implement urban flood control and drainage measures. All localities and relevant departments should specifically focus on the defense of key urban flood parts such as bridges and culverts, tunnels, concave overpasses, water-crossing roads, low-lying waterlogging-prone areas, underground spaces, rail transit, traffic roads, etc., pre-set flood control and drainage facilities and equipment in advance, set up obvious warning signs, and take hard isolation measures to seal and control at critical moments to prevent vehicles and pedestrians from entering by mistake and causing danger. According to the forecast of the meteorological department, rainfall may occur at night. All regions and relevant departments should strengthen inspections and duty, arrange rescue teams in advance, and deal with emergencies in time.

Immediately carry out transfer and hedging work. Do a good job in personnel transfer to avoid risks, especially in areas with forecast heavy rainfall and overlapping multiple rainfalls, and immediately organize mass transfer and properly resettle them. During this heavy rainfall process, it will be accompanied by strong convective weather such as thunderstorms and strong winds. It is necessary to strengthen the anchorage and reinforcement of unpowered ships, high-altitude structures, advertising information boards, building tower cranes, dangerous buildings and simple sheds, implement maritime traffic control in a timely manner, and timely evacuate offshore ships and personnel.
