How big is the impact of typhoon on Hainan?

After the typhoon makes landfall, there will be strong winds and heavy rains in various areas of Hainan Island, with winds of over 9 and instantaneous winds of over 12. Heavy rain will cause natural disasters such as mountain torrents and mudslides, which will pose a threat to people's lives and property.

During the typhoon, it is mainly to prevent the collision, anchoring and fire of fishing boats gathered in fishing ports, as well as the risk of casualties and property losses caused by illegal acts such as fishing boats or "three noes" ships sailing against the wind, not returning to Hong Kong to take shelter from the wind as required, and turning off communication and navigation equipment to escape supervision.

According to the statistics of the information management department, during the typhoon in 2022, there were 7 disastrous waves and 3 storm surges with water increase of more than 30 cm. It is estimated that the typhoon wave process affecting the South China Sea in 2023 may be close to normal or slightly more; There will be two or three storm surges in Hainan Island, and the water will increase by more than 30 cm.

Therefore, during the typhoon, important areas and facilities such as offshore ships, offshore fortifications, key coastal projects, coastal tourist areas, fishing ports and aquaculture areas may be affected by disastrous waves and storm surges. Low-lying areas vulnerable to storm surges in the northeast of Hainan Island need to be alert to flood risks.

Typhoon response measures

1. Strengthen the defense. All regions should strengthen defense work, especially coastal cities and mountainous areas, do a good job in flood control, wind prevention and tsunami prevention, evacuate dangerous areas, and ensure the safety of people's lives and property.

2. Stop sailing to avoid the wind being affected by typhoon. Ships should stop sailing to avoid the wind, and passengers should adjust their trips in time to avoid unnecessary losses.

3. Strengthening Crop Protection Farmers should take timely measures to protect crops and reduce economic losses. The government should also provide necessary help to ensure farmers' production and life.

In a word, typhoon is a natural disaster, and we can't change its coming, but we can reduce its impact and ensure the safety of people's lives and property through scientific prevention and response measures. I hope everyone will remain vigilant and take precautions.
