Is Beihai Prone to Direct Typhoon Hits? How High Is the Risk?

Beihai's Typhoon "Hit Rate" and Risk Characteristics
Beihai, Guangxi, is located at the top of the Beibu Gulf (Gulf of Tonkin), featuring a unique geographical position. Historical meteorological data indicates that Beihai is indeed an area frequently affected by typhoons. However, the definition of a "direct hit" requires a scientific perspective. According to the national standard for tropical cyclone classification by the China Meteorological Administration (CMA), a location suffers the most intense wind and rain impact only when the typhoon center passes over or very close to it. Since the Beibu Gulf is a semi-enclosed bay, typhoons entering this海域 often have their intensity weakened due to land friction or energy dissipation over the sea. Therefore, compared to the coastal areas of Guangdong or eastern Hainan, the probability of Beihai experiencing a direct landfall by a super typhoon (Category 16 or above) is relatively lower. However, this does not imply low risk. Even without a "direct landfall," Beihai is still highly susceptible to persistent gales and heavy rains due to the combined influence of the typhoon's outer spiral rainbands and the monsoon trough.
Analysis of Major Disaster Risks
The typhoon risks facing Beihai are mainly concentrated in the following three aspects, which residents should pay close attention to:
- Storm Surges and Seawater Backflow: This is the disaster Beihai needs to be most vigilant about. Due to its low-lying terrain and indented coastline, when strong winds from a typhoon push seawater toward the shore, especially if it coincides with an astronomical high tide, severe storm surges can easily occur, leading to seawater backflow in low-lying coastal areas.
- Urban Waterlogging Caused by Heavy Rainfall: Precipitation brought by typhoons is often characterized by high intensity and long duration. Beihai's urban drainage system may face pressure under extreme rainfall, with water accumulation likely in some low-lying road sections, affecting traffic and even threatening the safety of underground spaces.
- Wind Damage: Although the intensity may weaken, gusts can still reach forces 10-12, which is sufficient to snap trees and billboards, and even cause damage to houses.
Defense Guidelines and Emergency Response
In the face of typhoon threats, scientific defensive measures can minimize losses to the greatest extent. First, closely monitor warning signals issued by meteorological departments. China's typhoon warnings are divided into four levels: Blue, Yellow, Orange, and Red. The darker the color, the higher the danger level. When a Yellow warning or higher is issued, it is recommended to stop outdoor group activities; if a Red warning is issued, it usually means emergency measures such as school suspensions and work stoppages are required. Please note that standards may vary by location; please refer to the announcements from local authorities.
Secondly, prepare home protections:
- Clear flower pots and debris from balconies, reinforce doors and windows, and prevent objects from falling from heights.
- Reserve at least 3 days' worth of drinking water, ready-to-eat food, and common medicines. Prepare flashlights and power banks to cope with potential power and internet outages.
- Residents living in low-lying areas or dilapidated houses should cooperate with government arrangements in advance and evacuate to safe shelters in a timely manner.
Finally, do not rush to go out after the typhoon has passed. Be wary of broken power lines, fallen trees, and contaminated standing water. Staying calm and following official guidelines is the most reliable way to respond to typhoons. Real-time typhoon tracks can be queried at TyphoonSays (taifengshuo.com)
