This year's No.8 typhoon "Morakot" landed in Xiapu County, Fujian Province at 6: 20 today/kloc-0, which was a typhoon-level landing. At 17, its center is still located in Xiapu, about 530 kilometers south-southwest of Shanghai, that is, 26.6 degrees north latitude and 120.0 degrees east longitude. The maximum wind force near the center is12 (33m/s), with a radius of 350km for the level 7 gale circle and 80km for the level 10 gale circle. At present, the typhoon center is moving to the north-north direction at a speed of about 10 km per hour, and will gradually turn to the north direction in the future, and its intensity will be obviously weakened. It is expected that Morakot will reach the same latitude in Shanghai at night 10, then turn northeast and enter the Yellow Sea at night 1 1.

Rain forecast for this city: due to Morakot's influence, there will be obvious rain and wind weather in 1 1 Japan tonight (mainly from midnight today to tomorrow morning), and the process rainfall can reach 70 ~ 90 mm, with local 100 ~ 150 mm; The urban wind force is 6-8, the Yangtze River estuary and the coastal areas along the Yangtze River are 7-9, and the Shanghai coastal sea surface and Yangshan port area are 9- 1 1.

Weather forecast for Taihu Lake Basin: Influenced by Morakot, it is predicted that there will be obvious wind and rain in Taihu Lake Basin from midnight to 1 1, with rainfall of 80- 120mm and strong winds of 7-9.
