According to the monitoring results announced by the National Climate Center on the 21st, the plum rain season has begun in the Jiangnan region, the middle and lower reaches of the Yangtze River and the Jianghuai region in recent days. After the plum season, short-term heavy precipitation, thunderstorms and strong winds, tornadoes, and hail will occur frequently. The frequency and intensity of local heavy precipitation will increase. It is necessary to take precautions against floods in small and medium rivers, urban heavy rains, flash floods, and geological disasters.
At the same time, in the next few days, there will be heavy rains in the south and thundershowers in the north. Pay attention to prevent heavy rains, strong convective weather and secondary disasters.
The rainy season is in full swing and strong convective weather is active
According to relevant national standards, the areas where plum rain is prevalent in my country are divided into the Jiangnan region, the middle and lower reaches of the Yangtze River and the Jianghuai region.
The National Climate Center predicts that plum rains will begin on June 18 in the Jiangnan region and the middle and lower reaches of the Yangtze River, which is later than normal. The plum rain period is expected to be shorter than normal. Among them, the intensity of rainfall in the Jiangnan region is relatively strong, and the plum rain volume is 10 to 30% more than normal; the precipitation in the middle and lower reaches of the Yangtze River is relatively strong in phases, and there is a high possibility of local catastrophic heavy rainfall. The plum rain season will begin on June 19 in the Jianghuai region, which is earlier than normal. The plum rain period is expected to be shorter than normal. The amount of plum rain will be close to normal, and the intensity will be stronger in phases.
Experts from the National Climate Center said that strong convective weather will occur frequently after May. Affected by global warming, the frequency and intensity of local heavy rainfall in my country are increasing and becoming more extreme. It is recommended to prevent river flood control, urban heavy rains, flash floods and geological disasters.
Heavy rains hit many places in the south, alert to secondary disasters
The recent heavy rains and strong convective weather in many places in the middle and lower reaches of the Yangtze River show the weather characteristics of frequent short-term heavy rainfall and "violent plum rain" in the plum rain season. At the same time, there have been heavy rains in many places in South China, Southwest China and other regions recently.
The Central Meteorological Observatory will continue to issue a yellow rainstorm warning at 10:00 on the 21st. It is expected that heavy to heavy rains will occur in parts of 19 provinces including Hubei and Jiangxi from 14:00 on the 21st to 14:00 on the 22nd. Among them, heavy rainstorms occurred in parts of northern Hunan, southeastern Hubei, northwest Jiangxi, southern Anhui, southern Jiangsu, northern Guizhou, northern Guangxi, and southeastern Chongqing, and there were extremely heavy rains in local areas. Some of the above-mentioned areas are accompanied by short-term heavy rainfall, and there are local strong convective weather such as thunderstorms, strong winds or hail.
The Central Meteorological Observatory predicts that in the next 10 days, there will be 250 to 350 millimeters of precipitation in parts of southern Anhui, northern and western Hunan, northern Guangxi, and southeastern Guizhou, with local rainfall reaching more than 400 millimeters.
Experts remind that Anhui, Hunan, Guangxi, Guizhou and other places have heavy cumulative rainfall and high disaster risks. They need to pay attention to small and medium-sized river floods, mountain torrents, geological disasters, urban waterlogging, farmland waterlogging and other disasters caused by continuous heavy rainfall. In particular, they need to pay attention to the water level changes of Dongting Lake and Poyang Lake in the middle reaches of the Yangtze River.
Thunderstorms in North and Northeast China, beware of severe convective weather
During the Dragon Boat Festival holiday, showers and thunderstorms occurred in many places in the north, which had a certain impact on transportation and outdoor activities.
The Central Meteorological Observatory will continue to issue a blue warning for severe convective weather at 10:00 on the 21st. It is expected that from 14:00 on the 21st to 14:00 on the 22nd, thunderstorms with level 8 or above or hail will occur in parts of eastern Inner Mongolia and northwest Northeast China. Some areas in northeastern Inner Mongolia, northern Northeast China, southern North China, and northern Huanghuai will have short-term heavy rainfall with hourly rainfall greater than 20 mm.
Experts remind that in the next 10 days, North China and Northeast China will experience low temperatures and frequent showers or thunderstorms. In some areas, there will be heavy to heavy rains, and local thunderstorms, strong winds or hail, so precautions should be taken.
