Friends in the areas mentioned above should arrange travel plans reasonably, and pay attention to the forecasts and warning information for the coming days.

Meteorological warning information

is a key focus of people’s daily attention

Red, orange, yellow, blue

Heavy rain, typhoons, lightning

……….

What do warning signals of different colors “tell” you?

How is warning information produced?

What should you do after receiving a warning signal?

Do you understand all of this?

The making of a meteorological warning message

In total, how many steps is it divided into?

The answer is: 4 steps

Monitoring: The production of warning information begins with a “sky-air-ground” integrated 3D monitoring network. Meteorological departments use observation equipment such as meteorological satellites, weather radars, and automatic weather stations to capture atmospheric changes 24 hours a day without interruption. Massive real-time data, such as winds, pressure, humidity, temperature, and precipitation, are continuously collected.

Forecasting: Based on these data, forecasters conduct comprehensive analysis using models such as numerical forecasting models and artificial intelligence algorithms, and combine historical data and real-time evolution trends to judge the possible time, location, intensity, and impact range of disasters.

Warning: When it is judged that disasterous weather such as high temperatures, heavy rain, or severe convective conditions is about to occur, and it meets warning standards, the relevant meteorological stations will create corresponding meteorological disaster warning signals or risk warnings.

Release: At the earliest opportunity, the warning information is sent via the “National Emergency Warning Information Release System,” and through SMS, instant messaging flashes, and telephone channels targeting people responsible for emergency response at all levels, as well as through channels for the public such as radio and television, new media, village loudspeakers, electronic display boards, etc.

After the public receives a warning signal

What should they do?

How should different color warning signals be handled?

For blue and yellow warning signals, they mean that a disaster may occur, or it has already occurred and the impact is gradually worsening. During this time, the focus is on “preparation and prevention”—keep an eye on weather changes in time, take response measures in advance, and try to avoid going to dangerous areas.

When an orange or red warning is issued, it means that the disaster has already caused or is about to cause a serious threat, and the highest level of protective measures must be taken.

Warning signals ≠ “Just take a wait-and-see approach”

In daily life, the public should also build a risk awareness. Don’t ignore disasters just because they are “rare,” and don’t become complacent because they are “familiar.” You must deeply recognize that high-level warning signals are action directives for risk avoidance. Once you receive a warning, you must immediately initiate protective measures—not “wait and see.” Be the first person responsible for disaster prevention for yourself and your family; don’t wait for others. Master key risk-avoidance skills and trust official warning information.

Disasterous weather such as thunderstorm strong winds, hail, and heavy precipitation

also easily triggers disasters such as flooding

Everyone should be sure to pay timely attention to weather changes when traveling

If you encounter disasterous weather, learn to avoid risks scientifically
