The role of early warning:

1. Guarantee life safety: Early warning can inform the public of dangerous situations in time, such as natural disasters (typhoon, earthquake and flood), bad weather (rainstorm, snowstorm and thunderstorm) or other unexpected events (fire, terrorist attacks, etc.). ), so that people have enough time and opportunities to take escape, refuge and self-protection measures, thereby reducing casualties.

2. Prevention and reduction of losses: The release of early warning can remind the public to take timely measures to reduce losses. For example, in the case of typhoon warning, people can strengthen their houses, pack up outdoor items and buy enough food and water to reduce property losses.

3. Assist in emergency rescue and disaster management: Early warning can provide information to relevant departments and rescue agencies in time to help them make decisions and allocate resources. After an emergency occurs, early warning can guide people to act according to the instructions of relevant departments, thus improving the efficiency of emergency rescue and reducing the socio-economic impact of disasters.
