Suspension measures for red rainstorm warning:
When the rainstorm red warning signal was released, it was divided into five time periods according to students' school time: before school, on the way to school, during the morning and lunch break, and in the afternoon and on the way to school, and corresponding defense guidelines were formulated.
Before school:
An early warning signal will be issued before 6:30, and primary and secondary schools and kindergartens in the city will be closed all day.
On the way to school:
An early warning signal was issued from 6: 30 to 8: 00, and all primary and secondary schools and kindergartens in the city were closed all day.
Students who don't leave home for school should stay at home.
Schools will continue to be open, and at the same time, special personnel should be assigned to protect students and children entering the park.

Hazards of rainstorm:
1, waterlogging disaster
Because of the sudden and heavy rain, poor drainage is easy to lead to waterlogging, which makes soil pores full of water, leads to hypoxia of terrestrial plant roots, inhibits root physiological activities, and makes crops suffer and reduce production.
In cities and towns, when too much rain exceeds the drainage capacity, water will flow on the road surface, and water will form in low-lying areas, resulting in urban waterlogging, which will have a great impact on transportation, industrial production, commercial activities and citizens' daily life.
2. floods
Floods caused by heavy rain flooded crops, making it difficult for crops to metabolize normally and causing various injuries. The deeper the flooding, the longer the flooding time and the more serious the harm to agriculture, forestry and fisheries.
Rainstorm causes river flooding, and also causes geological disasters such as mountain torrents, landslides and mudslides, which not only harms crops, but also damages farm houses, industrial and agricultural facilities and roads, and even causes human and animal casualties and serious economic losses.
Flooding disasters in the history of China are almost always caused by rainstorm, such as July flood in the Yangtze River basin 1954, August flood in Hebei province 1963, August flood in Henan province 1975, June flood in Jianghuai region 19 1, and flood in the whole Yangtze River basin/kloc-.
