Understand storm levels correctly to proactively respond

(Chinhphu.vn) – According to the National Center for Hydro-Meteorological Forecasting, understanding the levels of storm winds and their impacts is extremely necessary so that each person can proactively prevent and protect their property and lives.

Understanding the levels of storm winds and their impacts is extremely necessary so that each person can proactively prevent and protect their property and lives.

Whenever a storm is forecasted, people are often concerned about the intensity of the storm but do not really understand the different storm levels. In fact, each storm level is not just a number but also represents different levels of danger and destruction. Understanding the storm wind levels and their impacts is extremely necessary so that each person can proactively prevent and protect their property and lives. Below are studies that have been applied in forecast bulletins:

Tropical Depression : The first sign of a natural disaster. Before becoming a storm, a common weather pattern is a tropical depression. This is the first stage, but it is also important to note:

Tropical depression - level 6

Wind speed: From 10.8 to 13.8 meters/second (equivalent to 39 to 49 kilometers/hour).

Impact: Trees sway, pedestrians begin to have difficulty walking against the wind. Seas become rough, beginning to pose a danger to small boats.

Tropical depression - level 7

Wind speed: From 13.9 to 17.1 meters/second (equivalent to 50 to 61 kilometers/hour).

Impact: Stronger winds, causing significant difficulty for pedestrians. Rougher seas, increased danger to boats.

Hurricane: As winds increase in intensity, a tropical depression develops into a hurricane. This is when we need to be especially vigilant.

Storm - level 8

Wind speed: From 17.2 to 20.7 meters/second (equivalent to 62 to 74 kilometers/hour).

Impact: Winds begin to break tree branches and rip roofs off weak structures. Pedestrians find it nearly impossible to walk against the wind. Seas become very rough, posing a great danger to ships.

Storm - level 9

Wind speed: From 20.8 to 24.4 meters/second (equivalent to 75 to 88 kilometers/hour).

Impact: Stronger winds, which can knock down trees. Many weak structures begin to suffer more damage. Very rough seas, which are extremely dangerous for boats.

Severe Storm : As the storm reaches severe intensity, the potential for damage increases significantly.

Strong storm - level 10

Wind speed: From 24.5 to 28.4 meters/second (equivalent to 89 to 102 kilometers/hour).

Impact: Very strong winds can knock down trees, damage homes and power lines. This is a very serious level of damage. Rough seas pose a great danger to boats.

Strong storm - level 11

Wind speed: From 28.5 to 32.6 meters/second (equivalent to 103 to 117 kilometers/hour).

Impact: Causes severe damage to non-permanent structures. Very dangerous for ships and coastal residents. Infrastructure such as roofs and windows may be severely damaged.

Very Strong Hurricane : When a hurricane reaches the "very strong" category, its destructive power can cause major disasters.

Very strong storm - level 12

Wind speed: From 32.7 to 36.9 meters/second (equivalent to 118 to 133 kilometers/hour).

Impact: Extremely destructive. Winds can blow down trees, completely destroy fragile structures, and cause severe damage even to large buildings. Small ships, if not properly anchored and cushioned, can be broken and sunk in ports and docks.

Very strong storm - level 13

Wind speed: From 37.0 to 41.4 meters/second (equivalent to 134 to 149 kilometers/hour).

Impacts: Extremely destructive winds, causing some damage to homes and utilities. High waves and flooding near the coast destroy small structures, large structures may be damaged by debris. Large ships sink.

Very strong storm - level 14

Wind speed: From 41.5 to 46.1 meters/second (equivalent to 150 to 166 kilometers/hour).

Impact: Continues to cause enormous destruction. Extremely strong waves. Sinks large ships. Almost unpreventable disaster, requiring emergency response and large-scale evacuation.

Very strong storm - level 15

Wind speed: From 46.2 to 50.9 meters/second (equivalent to 167 to 183 kilometers/hour).

Impact: Causes extremely severe damage, with little chance of prevention. Tremendous winds can flatten large areas.

Super typhoon: This is the highest and most dangerous level of typhoon, capable of causing catastrophic consequences.

Super typhoon - level 16

Wind speed: From 51.0 to 56.0 meters/second (equivalent to 184 to 201 kilometers/hour).

Impact: Extremely destructive, beyond imagination. Extremely strong waves, capable of sinking large ships. Extremely catastrophic damage, requiring urgent and large-scale response.

Super typhoon - level 17

Wind speed: From 56.1 to 61.2 meters/second (equivalent to 202 to 220 kilometers/hour).

Impact: Maximum destruction, extremely strong waves. Extremely catastrophic damage. This is the level of storm that can cause widespread humanitarian and economic disasters, requiring the highest level of preparedness and response from authorities and communities.
