According to the EPA's forecast, before noon today (2/26), the wind speed in the western half of the country was weak and local fog occurred. As the sea breeze has not yet strengthened, in addition to weak wind and poor diffusion conditions, the weak north wind will guide the wind. The pollution in the area is going south, and you need to pay attention to the slight deterioration of the air. Mayor Huang Weizhe specially reminded: Dear citizens, please remember to wear a mask when you go to work or go out, and avoid strenuous outdoor exercise!
