Local heavy rain or heavy rain, some of the above-mentioned areas will have short-term heavy precipitation, the hourly rainfall is 20-50 mm, and the local area can reach more than 60 mm; in addition, eastern Qinghai, western Henan, western Hubei, southern Zhejiang, southern Fujian, Guangdong There will be local thunderstorms, strong winds or hail in places like the east.
2Typhoon “Saddle” will affect the waters of southern my country
The center of this year’s No. 9 typhoon “Masa” (tropical storm level) is located on the Pacific Northwest Ocean about 325 kilometers northeast of Manila, Philippines at 5 pm today (22nd), which is 16.2 degrees north latitude and 123.5 degrees east longitude. The maximum wind force near the center is 8 (20 m/s), the lowest pressure in the center is 995 hPa, and the radius of the seventh-level wind circle is 160-200 kilometers.
It is expected that the “Saddle” will first move to the northwest at a speed of 10-15 kilometers per hour, and will move into the northeastern sea surface of the South China Sea in the early morning of the 24th, gradually approaching the coast of Guangdong, and its intensity will continue to increase. The strongest can reach the level of a severe tropical storm. (level 10-11, 25-30 m/s), and will land on the above-mentioned coast during the day on the 25th (23-28 m/s, level 9-10, tropical storm level or severe tropical storm level), the intensity after landfall gradually weakened.

4. Influence and Concern
1. There is a lot of rainfall in the eastern part of Northwest China, North China and other places. It is necessary to prevent the adverse effects of continuous rainfall and local short-term heavy rainfall on transportation and urban operation, and strengthen the prevention of local strong convective weather hazards;
2. Pay attention to the future development trend of “Saddle” and prevent the hazards of typhoons;
3. Pay attention to the development trend of high temperature in the southern region and its adverse effects on energy supply, water resources allocation, sanitation and epidemic prevention, and human health;
4. Development trends and impacts of drought conditions from the Sichuan Basin to the middle and lower reaches of the Yangtze River.
