What is a heavy rainstorm?

Heavy rainstorms refer to weather in which rainfall is greater than or equal to 100 mm in 24 hours.

One of the most distinctive features of heavy rainstorms is the large amount of precipitation. In some special circumstances, the rainfall of heavy rainstorms can even reach hundreds of millimeters or even more. This substantial increase in precipitation will have a great impact on people's production and life, such as causing floods and traffic jams.

Another characteristic factor of heavy rainstorms is high rainfall intensity. Precipitation intensity refers to the amount of precipitation per unit time. Heavy rains usually appear as intense precipitation in a short period of time, and the intensity of precipitation can reach tens of millimeters or even hundreds of millimeters per hour. This kind of heavy precipitation can lead to instant floods, flash floods, mudslides and other disasters, posing a threat to people's property safety.

Precautions during heavy rainstorms

1. Do not go out easily during heavy rainstorms. Try to take shelter at home safely, and do not take vehicles to your destination.

2. If people have to go out in the rain, they must wear relevant rainproof equipment, such as raincoats, waterproof shoes, etc., to ensure the safety of themselves and their families.

3. When encountering stagnant water, do not try to walk through it, because you may encounter a situation where there is no shore to stand on. You should especially not walk or stay near rivers or areas prone to flash floods.

4. Close the doors and windows at home to ensure that the home is not flooded by heavy rain; at the same time, check whether the doors and windows are tight and check if there are no leaks.

5. Keep the phone open or have an emergency power supply, set aside enough food and medicine as backup, and record the location of important items so that they can be accessed at any time.
