Typhoon Blue Warning Signal.

Criteria: Tropical cyclones are likely to be or have been affected within 24 hours, with average winds of 6 or higher along the coast or land, or gusts of 8 or more and may continue.

Defense Guide: Yellow Typhoon Warning Signal.

Criteria: Tropical cyclones may be or have been affected within 24 hours, with average coastal or land winds of 8 or more, or gusts of 10 or more and may continue.

Typhoon Orange Warning Signal.

Criteria: Tropical cyclones are likely to be or have been affected within 12 hours, with average coastal or land winds of 10 or more, or gusts of 12 or more and may continue.

Typhoon Red Warning Signal.

Criteria: Tropical cyclones are likely to be or have been affected within 6 hours, with average coastal or land winds of 12 or more, or gusts of 14 or more and may continue.

The Typhoon Blue Warning is the lowest level of the Typhoon Warning; Warning Signal Meaning: It may be affected by tropical depression within 24 hours, with an average wind force of more than 6 or gusts of 7 or more.

The Yellow Typhoon Warning Signal indicates that a tropical cyclone is likely to be or has been affected within 24 hours, with average winds of 8 or higher along the coast or on land, or gusts of 10 or more and may continue. A typhoon is a type of tropical cyclone.

A tropical cyclone is a low-pressure vortex that occurs over the tropical or subtropical oceans and is a powerful and deep "tropical weather system". China divides tropical cyclones in the South China Sea and the Northwest Pacific into six categories according to the magnitude of the maximum average wind force (wind speed) near the center of the bottom layer, of which the wind force near the center is 12 or above, collectively referred to as typhoons. The arrangement from lowest to highest is blue, yellow, orange, red.

First, the Typhoon Blue Warning is the lowest level of signal, indicating that the average wind force along the coast or on land is above 6, or gust to 8 or higher within 24 hours and may continue.

Second, the Yellow Typhoon Warning is the second lowest-level signal, indicating that within 24 hours, the average wind force along the coast or on land reaches 8 or more, or the gust is 10 or more and may continue.

Third: Typhoon Orange Warning is the third lowest-level signal, which indicates that the average wind force along the coast or on land is 10 or higher, or the winds gusting to 12 or more are likely to continue within 12 hours.

Fourth, the Typhoon Red Warning is the highest level of signal, indicating that the average wind force along the coast or on land is 12 or higher, or the gust is 14 or more and is likely to continue within 6 hours.

Extended Materials. There are four levels of typhoon warnings: blue, yellow, orange and red. Among them, the red warning signal is the most terrifying, generally after the release of this level, it indicates that the typhoon is about to make a strong landfall in the local area, and it will bring some damage.

In addition, there is a white warning signal, and only Guangdong Province has set up a full lead belt country.

After the issuance of the general typhoon warning, the relevant areas will stop indoor and outdoor large-scale gatherings, suspend classes, and suspend businesses (except for special industries). Before a typhoon, people should stay in a safe place as much as possible. Water operations in relevant waters and passing ships shall return to the port to take shelter from the wind, strengthen port facilities, and prevent ships from anchoring, running aground and colliding.

Every time a typhoon makes landfall, it is almost always accompanied by heavy rainfall, which can reach four to five hundred milliliters of precipitation. Before the typhoon, it is necessary to do a good job of stockpiling daily food, goods, and drinking water.

Legal basis: On August 16, 2004, the China Meteorological Administration issued the Trial Measures for the Issuance of Early Warning Signals for Sudden Meteorological Disasters, which divided the typhoon warning signals into four levels: blue, yellow, orange and red.

Typhoon warning signals are indicated in blue, yellow, orange and red:

Typhoon Blue Warning Signal – Tropical cyclone may or has been affected within 24 hours, with average winds of 6 or higher along the coast or on land, or gusts of 8 or more and may continue.

Yellow Typhoon Warning Signal – Tropical cyclone may or has been affected within 24 hours, with average winds of 8 or higher along the coast or on land, or gusts of 10 or more and may continue.

Typhoon Orange Warning Signal – Tropical cyclone may be or has been affected within 12 hours, with average winds of 10 or higher along the coast or land, or gusts of 12 or more and may continue.

Typhoon Red Warning Signal – Tropical cyclone may be or has been affected within 6 hours, with average winds of 12 or higher along the coast or land, or gusts of 14 or more and may continue.

Blue is a grade 6-7; Red is grade 12 or higher; Yellow is a grade 8-9; Orange is a grade 10-11.

The Typhoon Blue Warning Signal is an early warning of severe tropical cyclones over the surface of tropical oceans, which is the lowest level of typhoon warning (except for Guangdong).

Meaning of the typhoon blue warning signal: It may be affected by a tropical depression within 24 hours, with an average wind force of more than 6 or gusts of 7 or more; Or already under the influence of a tropical depression, with an average wind force of 6-7, or gusts of 7-8, may continue.

Depending on the level of the typhoon, when the Blue Warning is issued, the typhoon is likely to be a tropical depression, i.e. winds of up to 6 or 7 at the centre, or 7 gusts to Sakura.

Typhoon warning signals are divided into four levels according to the approach time and intensity, which are indicated by blue, yellow, orange and red.
