China News Service, July 4th. According to the website of the Central Meteorological Observatory, the Central Meteorological Observatory predicts that from July 4 to 7, the "Siamba" residual circulation will continue to move northward. Affected by it and the westerly belt system, a huge rainfall belt It will run through the north and south of my country, and there will be heavy to heavy rains from South China to Northeast China.

Among them, from the 4th to the 5th, it is the concentrated rainfall period in Central China and East China; from the 5th to the 6th, it affects the North China and Shandong; from the 6th to the 7th, it affects the Northeast region; South China is the continuous rainfall.

  According to meteorological experts, the No. 3 typhoon "Siamba" landed in Dianbai, Guangdong at around 15:00 on July 2, with a typhoon-level intensity (level 12, 35 m/s) when it landed. It was the first typhoon to land in my country this year. .

At 8:00 this morning, the Central Meteorological Observatory has stopped numbering it.

  As the first landing time of this year, "Siamba" is stronger than the average annual landing intensity (level 11, 30.8 m/s), and 4 days later than the average landing time (June 28). It strengthened to a typhoon level offshore and made landfall at this intensity.

  Affected by it, from July 1st to 3rd, there were heavy rainstorms or heavy rainstorms in Hainan Island, the central and western and southern coasts of Guangdong, southeastern Guangxi, southern Hunan, and southeastern Fujian. The cumulative rainfall in the area reached 400-500 mm, and the Changjiang River in Hainan reached 581 mm; the daily rainfall of more than 50 stations in Hainan, Guangdong, Guangxi and other places reached the level of extremely heavy rain, and the Hainan Sanya National Meteorological Observatory broke the historical extreme value of the local daily rainfall. .

  At the same time, strong winds of magnitude 6 to 8 occurred in most waters of the South China Sea, the Paracel Islands, Zhongsha Islands, and the coast of South China, and gusts of magnitude 10 to 11 occurred off the Pearl River Estuary, the sea in the northeastern part of Hainan Island, and the waters near the Paracel Islands. A gust of magnitude 13 to 14 appeared on land, and a gust of magnitude 15 (45.8 m/s) was observed at Dashu Island, Yangxi County, Yangjiang, Guangdong.

  Affected by the "Siamba" and its surrounding cloud systems, short-term heavy rainfall occurred in many parts of southern China. The maximum hourly rainfall in western and southern Hainan exceeded 100 mm, and the Changjiang River in Hainan reached 137.5 mm. Tornadoes appeared in Chaozhou and Foshan in Guangdong, and Shantou. A "waterspout" appeared in the sea in Nan'ao County.

  After Typhoon "Siamba" brought strong wind and rain to southern China, its residual circulation will continue to affect my country.

It is estimated that from the 4th to the 7th, due to the joint influence of the westerly belt system, Guangxi, Guangdong, southern Yunnan, central and eastern Hunan, Jiangxi, central and eastern Hubei, western and northern Anhui, northwestern Jiangsu, eastern Henan, Shandong, and eastern Hebei are expected to , Beijing, Tianjin, Liaoning, Jilin, western and southern Heilongjiang, and northeastern Inner Mongolia have heavy rains, including eastern and southern Guangxi, northern and western Guangxi, eastern Hunan, western Jiangxi, eastern Hubei, northern Jiangsu and Anhui, central Shandong, There are heavy rainstorms in parts of central Liaoning, western Jilin and other places, and there are local heavy rainstorms; the maximum hourly rainfall is 30-70 mm, and the local area can exceed 70 mm.

  Meteorological experts reminded that the residual circulation of "Siamba" has a wide range of influences and a long duration of influence, involving many provinces (cities, districts) in the south and north, and the rainfall intensity is high in many places. May cause flash floods, geological disasters, small and medium river floods and urban and rural waterlogging.

The rainfall in Guangdong, Guangxi and other places has a long duration and overlapping areas. It is necessary to prevent the superposition effect of rainfall and strengthen disaster defense.

The public should also make reasonable travel plans according to the weather forecast, try to avoid travel during heavy rain, and pay attention to safety.
