The black rainstorm signal means that the rainfall in some areas has reached 100 mm or more in the past three hours, and the rainfall may continue. However, the black rainstorm signal has been cancelled. According to the new meteorological disaster warning signal, the rainstorm signal is divided into four grades: blue, yellow, orange and red.

The rainstorm warning signal is an early warning signal made by the meteorological department before the rainstorm comes through meteorological monitoring. In Chinese mainland, the red rainstorm warning signal is the highest, which indicates that in the past three hours, the rainfall in some places has exceeded 100 mm, and the rainfall may continue. In the Hong Kong Special Administrative Region, there are three levels (yellow, red and black), and the black rainstorm warning signal is the highest level. The Macao Special Administrative Region only has rainstorm warning signals.

The competent meteorological department of the State Council is responsible for the issuance, cancellation and dissemination of national early warning signals. The local competent meteorological departments at all levels shall be responsible for the administration of the release, cancellation and dissemination of early warning signals within their respective administrative areas. Other relevant departments shall, in accordance with their duties, cooperate with the competent meteorological departments in the release and dissemination of early warning signals.

In case of rainstorm, you should pay attention to the following points:

1. Pay attention to the weather forecast and early warning: pay attention to the weather forecast and early warning information released by the meteorological department in time to understand the weather changes and possible heavy rains.

2. Residents' safety: It is most important to ensure the safety of yourself and your family. Try to stay in a safe place and avoid going out. If you have gone out, find a safe place to shelter from the rain as soon as possible to avoid being trapped or in danger by heavy rain.

3. Prevention of flood and waterlogging disasters: Rainstorm is easy to cause flood and waterlogging disasters, so it is necessary to pay attention to preventive measures. Avoid being close to rivers, low-lying areas and areas prone to water accumulation, and try to avoid wading. If there is a river flooding around or the water level rises, you should evacuate to a safe place immediately.
