In recent days, the temperature has been rising day by day
I believe you feel it strongly
The "enthusiasm" of the summer too
Today (April 15)
The maximum temperature in the city is generally 30-32°C
Pingdi Street Liulian Station
The maximum temperature exceeded 34°C
Just ask you if it's hot?
I want to dry thick clothes
Friends with quilts should also hurry up
Because the weather is becoming more and more erratic in the middle and late part of the week

Specific weather
On the 16th, it was cloudy and sunny, and the weather was hot, with a maximum temperature of about 32 °C;
The weather was unstable from the 17th to the 22nd, with cloudy intermittent overcasts and occasional (thunder) showers, and the weather gradually became unstable in the middle and late part of the week, and the risk of severe convective weather increased.
Guangdong will enter a new round of active thunderstorms
According to @guangdongweather news, it is expected that starting on April 16, Guangdong will enter a new round of thunderstorm active period, and heavy precipitation and strong convective weather tend to be obvious.
The pre-flood season in South China usually refers to the period when precipitation is relatively concentrated in South China around April and June every year, and the precipitation during this period is mostly caused by the action of cold and warm air and the outbreak of monsoons.
First, from late March to early May every year, an appropriate amount of cold air crosses the South Ridge and the warm and humid air flow from the sea surface. Why is it a moderate amount of cold air? Because if the cold air is strong, it will push the warm and moist air out of the coastline, so that precipitation cannot be formed on land; if the cold air is weak, it will not be able to cross the Nanling Ridge, or it will not be able to provide enough energy for the warm and humid air to condense precipitation; if the cold and warm forces are basically equal, the two forces will go head-to-head, and you will come and go, bringing abundant precipitation in the pre-flood season, and the confrontation between cold and warm will also lead to the frequent occurrence of strong convective weather during this period.
Second, the South China Sea monsoon begins to break out after mid-May every year. After the monsoon landed, it was affected by factors such as the uplift of the land topography, which brought a wide range of continuous heavy precipitation to South China.
Since late March this year, due to the continued strong southerly winds, the "main battlefield" of cold and warm confrontation has been northerly as a whole, which has also led to frequent strong convective weather in Hunan, Jiangxi, and northern Guangdong in recent times;
According to the latest forecast of the Central Channel: It is expected that on the 16th and 17th, there will be moderate to heavy rain in Jiangnan, Jianghan, northern South China, the eastern part of the Sichuan Basin, and the central and eastern parts of Guizhou, accompanied by strong convective weather such as short-term heavy precipitation, thunderstorms, strong winds or hail.
Looking forward to the 18th and 20th, there will be light to moderate rain and locally heavy rain in the eastern part of Northwest China, western North China, Huanghuai and other places, and moderate to heavy rain in Jianghan, Jianghuai, Jiangnan, South China, Sichuan Basin and Guizhou, accompanied by strong convective weather.

3-5 typhoons are expected to "hit" Guangdong this year
According to the judgment and prediction of the Guangdong Provincial Three-Prevention Work Video and Telephone Conference, the heavy rain disaster in Guangdong this year may be more serious, and the frequency of typhoons is slightly less normal but the intensity is high. The climate forecast of the flood season shows that the total rainfall from April to September is slightly higher than normal, but the distribution is uneven, with more rainfall in the pre-flood season (April to June) and slightly less normal in the post-flood season (July to September).
It is expected that there will be 3~5 typhoons that will land or seriously affect Guangdong in 2024, compared with the multi-year average (5.8), the number is slightly smaller, the intensity is slightly stronger, the initial typhoon is later than the multi-year average (June 24), and the final typhoon time is close to the multi-year average (October 4).
Outdoor safety guidelines for thunderstorms
Keep away from electrical facilities
During thunderstorms, strong winds may break power overhead wires, while lightning strikes and heavy rain can easily cause short circuits and discharges of bare wires or transformers, posing a safety threat to the surrounding people. Therefore, during thunderstorms, try to stay away from power equipment such as power poles, transformers, and distribution boxes, and do not take shelter from the rain under transformers and overhead lines.
Avoid dangerous objects
Objects such as tall trees, billboards, and street lamps are at risk of being broken by high winds during thunderstorms, and taking shelter from these objects can be injured by falling from a height. At the same time, once the power poles, neon lights, traffic lights and other objects are scraped down and broken, the torn wires will cause electricity leakage when they come into contact with the ground water, which will cause a greater risk of electric shock to people moving nearby, so be sure to stay away.
Walk away from standing water
When walking during a thunderstorm, try to choose a section where there is no standing water. If you must wade through the water, it is recommended to carefully observe whether there are any electrical equipment such as bus stop advertising light boxes, street lights, and distribution boxes nearby, and ensure that no wires fall into the stagnant water, and do not overflow the base of these equipment, so as to avoid electric shock accidents caused by water conduction.
Don't move fast
It is not advisable to drive a motorcycle, electric car or bicycle quickly during a thunderstorm, and do not run wild in the rain, because the larger the stride of the body, the greater the stride voltage difference and the susceptibility to electric shock. The safest way is to stop nearby and find a safe place to wait for the rain to stop.
Someone falls and is not in a hurry to get close to the mix
In the case of not ensuring whether the person who has been electrocuted to the ground is electrified, do not save others with bare hands, otherwise not only will you not be able to save others, but also lead to electrocution yourself. If you find someone electrocuted in the water and fall to the ground, do not use wet tools or metal objects to pull the wires, and immediately call 120 for medical personnel to rescue the scene.
Close doors and windows for lightning protection
When you notice thunder nearby, even if it hasn't rained yet, close the doors and windows as soon as possible. The purpose of this is not only to prevent rain from wetting the contents of the house, but also to prevent lightning from hitting the room directly or ball lightning from drifting into the room and injuring people.
Water heaters are not used
Solar water heaters should not be used during thunderstorms because the panels of solar water heaters are mostly installed on the roof. Similarly, some metal objects installed on the façade of the house, such as gas pipes, water pipes, etc., should also be avoided as much as possible to avoid electric shock.
