Why is the central weather forecast not reported to Mianyang?

Mianyang city is not in the weather forecast. Central weather forecast refers to the use of modern scientific and technological means to predict the future state of the earth's atmosphere at a certain place, and then broadcast and publicize it. Mianyang city is not in the weather forecast, so it is not reported. Mianyang, a prefecture-level city under the jurisdiction of Sichuan Province, China Science and Technology City, the second largest economy in Sichuan, and a regional central city of Chengdu-Chongqing urban agglomeration, is located in the northwest of Sichuan Basin.
