What does the typhoon path color line mean?

The color line of typhoon path refers to different color bands, which are used to indicate different levels of typhoon influence.

Where the blue path indicates that it may or has been affected by tropical cyclones, the yellow path indicates that it may or has been affected by tropical cyclones, the orange path indicates that it may or has been affected by tropical cyclones within 12 hours, and the red path indicates that it may or has been affected by tropical cyclones within 6 hours. The wind level and duration on the colored line are determined according to the actual situation.

Typhoon is a kind of tropical cyclone. Tropical cyclone is a low-pressure vortex that occurs on the surface of tropical or subtropical oceans, and it is a powerful and profound "tropical weather system". In China, tropical cyclones in the northwest Pacific are classified into six grades according to the maximum average wind speed near the center of the surface layer, and the wind force near the center reaches 12 or above, which is collectively called typhoon.

Different path color lines of typhoon:

1. Blue path: It may be or has been affected by tropical cyclones within 24 hours, and the average wind force along the coast or land is above 6, or the gust is above 8 and may continue.

2. Yellow path: it may be or has been affected by tropical cyclones within 24 hours, and the average wind force along the coast or land is above 8, or the gust is above 10 and may continue.

3. Orange path: it may be or has been affected by tropical cyclones within 12 hours, and the average coastal or land wind force is above 10, or the gust is above 12 and may continue.

4. Red path: it may be or has been affected by tropical cyclones within 6 hours, and the average wind force along the coast or land is above 12, or the gust is above 14 and may continue.
