Shanghai was hit by heavy rain. What disasters will strong convective weather cause?

Hail, landslide, collapse, debris flow, tornado, etc.

Please try not to go out in case of heavy rain and lightning. Residents living in the building should immediately close the doors and windows, avoid places with metal pipes and cut off the power supply of household appliances. Electrical sockets and switches in low-rise residents' homes should be moved to a safe place above the ground 1 m. Don't stay on the balcony of a tall building, move the potted plants on the balcony to a safe place early. Can low-lying residential areas be demolished? Small encirclement? Measures, such as building fences, placing water baffles at the gate, and configuring small pumps. Once the outdoor water overflows into the house, the power supply should be cut off in time, and then the personnel should be moved to a safe area; Finally, take all effective measures to keep the water out of the door and eliminate indoor stagnant water.

When driving in heavy rain, be sure to turn on the lights.

When the rainstorm is too heavy, the visibility will be reduced, even a few meters. At this time, drivers and friends must turn on the lights, which can remind vehicles and pedestrians to see themselves clearly and prevent collisions. Slow down and keep moving slowly. Drivers and friends who drive must pay attention to slow down when encountering heavy rain, so as to avoid accidents such as collision caused by unclear road conditions, splashing water waves when driving fast, and being easily inhaled by the intake pipe, causing harm to the car. The distance between cars must be greater. Due to the low visibility during rainstorm, it is necessary to keep a large distance between cars (front and rear distance and left and right distance) to prevent rear-end collision and collision.

Any degree of wading should be driven slowly, and special attention should be paid to the protection of engines and computers. Because after the vehicle is soaked, the water entering the engine will accelerate the corrosion of the moving parts inside the engine under the action of high temperature, and the engine intake will be deformed or even scrapped if it absorbs too much water. In addition, too much water will enter the car, which may also endanger the on-board computer, resulting in the failure or damage of the electronic control system. Some lines are exposed to water, and the skin ages prematurely, resulting in cracks, which eventually leads to circuit failure. Especially for cars equipped with EFI engines, their control computers are very afraid of the tide. The car should always pay attention to the sealing of the computer to avoid the disorder of control caused by water entering the computer, which will lead to the paralysis of the whole car.
