　　Influence and concern

　　There is strong rainfall in Sichuan Basin and northern areas, so we should pay attention to the geological disasters of floods and flash floods in small and medium-sized rivers that may be caused by rainfall. North China, Huanghuai and other places should be alert to the adverse effects of strong convective weather such as thunderstorms and hail.
