Second, key weather forecasts
1. Domestic key weather
(1)Typhoon Magnon weakened into a tropical depression
This year's No. 7 typhoon "Mulan" has made landfall on the northeast coast of Vietnam around 4:30 a.m. today (11th) morning, with a maximum wind force of 8 (18 m/s, tropical storm level) and a minimum pressure of 998 hPa at the center. At 5 o'clock this morning, its center is located in Quang Ninh Province, Vietnam, with a maximum wind force of 7 (15 m/s, tropical low pressure) and a minimum pressure of 998 hPa in the center.
Due to the obvious weakening of the intensity of "Mulan" and the impact on the mainland, the Central Meteorological Observatory lifted the typhoon blue warning and the blue warning of heavy rain at 06:00 on August 11. However, affected by the residual circulation of "Mulan", from 08:00 on August 11 to 08:00 on August 12, there will be 6-7 winds in the western-western waters of the northern and central Parts of the South China Sea, the Qiongzhou Strait, the Beibu Gulf and the central and western coasts of Guangdong, the coast of Guangxi, the coast of Hainan Island, and the waters near the Xisha Islands, and some seas will have 8 and gusts of 9 to 10.
