Xiamen Meteorological Observatory upgraded and issued the "Heavy Rain Warning Level II" and maintained the "Typhoon Warning Level III". According to the "Xiamen City Flood Control and Typhoon Emergency Plan", our city raised the emergency response level for heavy rain and flood prevention to Level 2 at 9:00, and maintained the Level 3 emergency response for typhoon prevention. The public should pay attention to preventing disasters such as urban and rural waterlogging, flash floods, mudslides and landslides that may be caused by heavy rainfall.
Typhoon No. 9 "Lubi" (tropical storm level) this year is located on the offshore sea surface about 30 kilometers south-east of Shantou City, Guangdong Province (23.1 degrees north latitude, 116.8 degrees east longitude) at 08:00 today. The maximum wind force near the center is 9 level (23 meters/second), the lowest central air pressure is 985 hPa.
It is expected that the center of the typhoon will move northward at a speed of about 10 kilometers per hour, and will soon land on the coast from Shantou, Guangdong to Chaozhou . After landing, the intensity will weaken and it will gradually move northeast.
Heavy rains have occurred in some towns and streets in our city in the past 24 hours. It is expected that from today to the 8th, there will still be heavy rains to heavy rains in our city and offshore areas. During the process, the cumulative surface rainfall can reach 180 to 250 mm, with local rainfall exceeding 300 mm. The maximum hourly rainfall intensity can reach 50 to 80 mm.
It is expected that from today to the 8th, the maximum gusts from Chongwu to Dongshan coast will reach level 9 to 11; The southern part of the Taiwan Strait will reach level 10 to 12; the winds in Xiamen's inland sea and high-altitude mountainous areas will reach level 7 to 8, with gusts of 9 to 11 class.
"Lu Bi" generated in Nanhai has a short time from generation to landing, a complex and changeable path, a long rainfall process, a large amount of rain, and strong rainfall in certain periods and areas, facing the triple pressure of wind, rain, and tide. This is the first typhoon to have a major impact on our city this year.
The Municipal Flood Control and Drought Relief Headquarters requires that all districts and member units strengthen typhoon and rain prevention work, strengthen duty watch, and promptly prevent and deal with emergencies. Due to the heavy rainfall in the past few days, special attention must be paid to preventing secondary disasters such as flash floods, collapses, landslides, and debris flows caused by heavy rains, and resolutely relocate people in dangerous areas. It is necessary to strengthen inspections of dangerous areas such as flood-prone risk points, dredge debris at drainage outlets in a timely manner, and prepare emergency rescue forces in advance to prevent leakage of electricity in flooded areas from injuring people.
Concerns and Suggestions
1. It is expected that the heavy precipitation will last for this period and the cumulative precipitation will be large. Currently, our city has a high geological disaster risk (Level 2, orange). We must pay attention to the flash floods and urban and rural waterlogging caused by the superposition effect of heavy precipitation. , landslides and other secondary disasters.
2. Pay attention to the adverse effects caused by strong thunder and lightning, short-term strong winds and other strong convective weather.
3. Vessels sailing or operating in typhoon-affected sea areas should return to port in time to take shelter or avoid typhoon-affected areas. Pay attention to the adverse effects of strong winds on maritime shipping and coastal activities.
【Flood Prevention Data】
In terms of hidden danger investigation, a total of 713 safety hazards have been investigated, 553 have been rectified, and the remaining hazards are being rectified at an accelerated pace.
In the maritime field, as of 18:00 on the 4th, coastal scenic spots have been closed; starting from 18:00, passenger ships, yachts, and sailboats have stopped sailing one after another, construction ships have stopped working, and all people on unpowered ships have been evacuated ashore.

In terms of dangerous areas, inspections and inspections of key locations such as old houses and low-lying flood-prone areas have been strengthened. Inspection, monitoring, and warning measures have been implemented at all 81 disaster spots in the city.
In terms of waterlogging prevention, a total of 104 waterlogging points were counted, 9 waterlogging points were listed and supervised, and 85 have been rectified. All waterlogging points that have not been rectified have implemented rescue forces and equipment presets.
In terms of underground space, establish and improve flood prevention plans for track construction and operation, strengthen inspections of potential safety hazards at subway construction sites and operating sites, and strengthen inspection and maintenance of drainage facilities in underground garages and underground shopping malls to prevent accumulation of water.In terms of construction sites, we will implement defensive measures for important locations such as new airports and new cities, and strengthen safety management of tower cranes, deep foundation pits, and simple work sheds.
