Hello dear friends! Welcome to Xiaoyu's happy world! Thank you for your likes and attention! I wish you all a happy life, a rolling source of wealth, a dream come true, and a peaceful and happy life every day!
"There are unpredictable circumstances in the sky, and people have good and bad luck." At 6 a.m. on July 29, the Central Meteorological Observatory issued a new round of orange warning for heavy rain and a blue warning for severe convective weather.
The amount of heavy rain in Hubei, Hunan, Chongqing and other places is staggering, and local areas are more likely to experience extremely heavy rains. What is the impact of these warnings? Are the countermeasures in place?

Orange Warning for Heavy Rain and Severe Convective Weather: The latest bulletin from the Central Meteorological Observatory
In China's meteorological early warning system, the orange warning for heavy rain can be described as one of the high-risk signals. In the early morning of July 29, 2024, the Central Meteorological Observatory once again pressed the "start button" of the rainstorm warning and issued an orange warning for heavy rain and a blue warning for severe convective weather.
This decision is undoubtedly worrying for many people, because behind it is not just a few rains, but an extreme weather challenge that may affect many provinces and cities.
The true power of an orange rainstorm warning
From 08:00 on July 29 to 08:00 on the 30th, this warning covered many provinces and cities such as western Hubei, northwest Hunan, and most of Chongqing. Residents in the affected areas may face heavy rain, heavy rainstorms or even extremely heavy rains. This intensity of precipitation not only brings trouble to daily life, but also can cause secondary disasters such as flash floods, landslides, and mudslides.
Let's look at the details of the warning. Rainfall in these areas is expected to be staggering, with localized rainfall of 250-260 mm.
To give everyone an intuitive feeling, take a bucket of 10 liters of water, can you imagine how many such buckets will be filled with 260 mm of rainwater? This is not just a light rain, but a "flood" is coming to us.
Threat of severe convective weather
In addition to heavy rain, severe convective weather is also an important part of this warning. It is expected that from 08:00 on July 29 to 08:00 on the 30th, thunderstorms, strong winds or hail will occur, affecting eastern Jilin, Liaoning, central Hebei and other places. These weather phenomena can not only cause damage to buildings, but can also cause problems such as traffic chaos and damage to farmland.
Short-term heavy precipitation is even more worrying. Rainfall can exceed 70 mm at its peak, which is a huge test for the city's drainage system. Imagine that the waterlogged road becomes a "man-made river", driving like drifting and pedestrians wading through water. It's like a "water park", but it's not what we want.
Interpretation of the Emergency Defense Guidelines
In the face of such extreme weather, the response of governments at all levels and relevant departments is particularly important. After the warning is issued, the government should quickly activate the emergency plan, cut off the dangerous outdoor power supply, suspend outdoor operations, and take special protective measures for disaster-prone areas such as schools and kindergartens to ensure personal safety.
At the same time, citizens need to be vigilant. Reduce activities in open areas, especially during thunderstorms and high winds, and try to stay in buildings that are wind-resistant and have lightning protection.
When encountering a waterlogged road section, the driver should slow down to ensure a safe passage. The "slow" here is not only a requirement for speed, but also a deep understanding of safety.
In terms of transportation, airports, railways, highways and other units need to take measures such as flight restrictions, speed limits or temporary closures to ensure traffic safety. Water traffic should also return to port to avoid risks, strengthen port facilities, and ensure the safety of ships.
Maintenance of urban drainage systems and disaster prevention
The heavy rain put the city's drainage system to a severe test. City planners need to regularly check the operation of the drainage network to ensure that it is effective in removing stagnant water from precipitation. Farmland drainage systems also need to be maintained in a timely manner to avoid damage to farmland due to poor drainage.
Especially in areas with a high incidence of geological disasters such as flash floods, landslides, and debris flows, it is necessary to formulate emergency plans in advance and strengthen monitoring and prevention and control preparations. Preparing for these things will not only reduce the cost of disasters, but also protect people's lives and property.
Summary and reflection
The issuance of an orange warning for heavy rain and a blue warning for severe convective weather remind us that the threat of extreme weather cannot be ignored. In the face of natural challenges, we need to respond in a timely and scientific manner to ensure maximum safety when disasters strike. Behind every warning is the hard work of countless meteorological workers and their deep concern for people's safety.
So finally, I would like to ask: Are you ready for such a severe weather warning? What steps would you take to protect yourself and your family in such extreme weather? What do you think about this?
