Heavy rainfall turned to the middle and lower reaches of the Yangtze River, and Huanghuai in North China was late in autumn.

  Cctv newsAccording to China Weather Network, yesterday (18th), a new round of rainfall in the south started from the southwest, with heavy rains in Chongqing and other places. It is estimated that today and tomorrow, the rainfall will expand eastward, and many places in the middle and lower reaches of the Yangtze River will be immersed in rain, with heavy rains in Anhui and Hubei. The rain gradually weakened on Thursday and ended. Most of the north is dominated by sunny weather, especially in North China and Huanghuai areas. The temperature is higher than normal, and the autumn process is sluggish.

  The Yangtze river basin is immersed in rain, and there are heavy rains in Hubei, Anhui and other places

  Beginning on the 18th, a new round of rainfall in the south started from the southwest. Monitoring shows that yesterday, heavy rains occurred in parts of eastern Chongqing, northeastern Guizhou, southwestern Hubei, northern Hunan and southwestern Guangdong, and heavy rains (100-174 mm) fell in Chongqing Youyang, Changde, Hunan and Yangjiang, Guangdong. The maximum hourly rainfall intensity in these areas was 65-88 mm.

  Today and tomorrow, this round of rainfall will rapidly expand eastward, with obvious rain in many places in the middle and lower reaches of the Yangtze River. The Central Meteorological Observatory predicts that there will be heavy rain or rainstorm in parts of Chongqing, Guizhou, southern Jianghan, western and northern Jiangnan and other places on the 19th and 20th, and there will be heavy rain locally, with the cumulative precipitation of 30-70mm and the local area reaching 100-150mm.

  It is estimated that there will be heavy rain or rainstorm in parts of southeastern Chongqing, southern and eastern Guizhou, southern Hubei, central and northern Hunan, northwestern Jiangxi and southern Anhui, among which there will be heavy rain (100-120 mm) in western and northeastern Hunan, and there will be short-term heavy precipitation in these areas, with the maximum hourly rain intensity of 20-40 mm and the local area of 50 mm or more. In response, the Central Meteorological Observatory issued a blue rainstorm warning at 6 o’clock today.

Heavy rainfall turned to the middle and lower reaches of the Yangtze River, and Huanghuai in North China was late in autumn.

  Tomorrow, the range of heavy rainfall will be slightly reduced, and the eastern part of the south of the Yangtze River will also join the ranks of rainfall. There are moderate to heavy rains in central and eastern Yunnan, western Guangxi, southern Jianghuai and northern Jiangnan, among which there are heavy rains (50-90 mm) in parts of southeastern Anhui, southern Jiangsu, Shanghai and northern Zhejiang.

  Under the pressure of rain, the eastern part of southwest China to the middle and lower reaches of the Yangtze River will also usher in a round of cooling process from west to east. Sichuan Basin and many areas in the west and north of Jiangnan will get rid of the summer heat above 30℃, and the maximum temperature will gradually drop to about 25℃, from high to short-term low, and the summer heat will gradually recede and cool.

  On Thursday (21st), this round of rainfall weakened and ended, and there will be an interval of about 3 days along the Yangtze River. According to the current forecast, there will be another obvious rainfall process from the Sichuan Basin to the northeast of the south of the Yangtze River from 23rd to 25th. Due to the long time limit, it is necessary to pay attention to the approaching forecast in time.

  According to the statistics of the last month, the rainfall in Chongqing, Guizhou and Hubei has been on the high side. The accumulated rainfall in this round is large, accompanied by short-term heavy rainfall in many places, and the maximum hourly rainfall intensity is 40-60 mm. The southwest region is fragile in geology, so it is necessary to guard against landslides, flash floods and other disasters caused by heavy rainfall. At the same time, the rain is accompanied by short-term heavy precipitation, so it is necessary to guard against disasters such as urban waterlogging. When the rain is fierce, try not to go out and pay attention to personal safety.

  Most areas in the north are sunny, and Huanghuai in North China is sluggish in autumn.

  Recently, the rainfall in most parts of the north is scarce, and it continues to be sunny, and the temperature is higher than normal. Yesterday, there was a high temperature of 35℃ in Shijiazhuang, which was the third high temperature record in history. In mid-September, there was still a high temperature that was rare in the local area.

  It is predicted that the temperature will drop in most areas from North China, Huanghuai to Northeast China today and tomorrow. Among them, today, the decline in eastern Inner Mongolia, northern Hebei and western Northeast China can reach 4-10 C, and the temperature drop is more significant, while the rest of the decline is mostly within 4 C. Tomorrow, many places in Inner Mongolia and Northeast China will begin to warm up, and the temperature in Huanghuai in North China will continue to fall. With the development of cooling, the range of 30℃ in North China, Huanghuai and other places will gradually shrink.

  Although the temperature in North China and Huanghuai has dropped slightly, it is still higher than normal, and the process of entering autumn is sluggish. At this time all the year round, Beijing-Tianjin-Hebei, most of Shandong and most of Henan have entered autumn, but these areas are still in the summer of meteorological significance this year.

  Take Beijing as an example. Autumn is on September 11th all the year round, but it has not yet entered autumn. Since the beginning of summer on May 7th this year, as of September 17th, the summer in Beijing has reached 134 days, which is not only much longer than the 111-day summer all the year round, but also broke the local historical record of the longest summer (133 days in 2007).

Heavy rainfall turned to the middle and lower reaches of the Yangtze River, and Huanghuai in North China was late in autumn.

  Judging from the forecast for the next week, most areas in North China and Huanghuai have avoided the "care" of rain, and the weather will continue to be fine and the temperature will continue to be warmer, and the autumn in this area will continue to be delayed. Among the provincial capital cities, Beijing, Tianjin, Shijiazhuang and Zhengzhou have all entered autumn later than usual this year, and "being late" is a foregone conclusion.

  The highest temperature in the above areas will reach about 30℃ during the day, and it will be a little hot during the day, especially in the afternoon, but it will drop rapidly at night. The temperature difference between day and night is generally above 10℃, and the weather is cold. Pay attention to adding clothes to keep warm when you go out in the morning and evening.
