海南岛东半部地区将有强降水 局地特大暴雨

海南省气象台10月7日发布预报，预计10月8日至9日，海南岛东半部地区将受偏东急流影响，出现一次强降水天气过程，其中局地将现特大暴雨1。琼州海峡和南沙群岛附近海面风力5～6级，雷雨时阵风7～8级；北部湾海面和西沙、中沙群岛附近海面风力5～6级、阵风7～8级，雷雨时阵风增大至9级1。

由于9月海南岛降雨较常年偏多两成，部分市县土壤饱和度高，此次强降水可能引发道路、桥梁沉陷或塌方1。气象部门建议相关部门做好中小型水库安全巡查工作，防御城乡积涝、农田渍涝、中小河流洪水、山洪和地质灾害，加强道路、桥梁巡查1。

The Hainan Meteorological Bureau issued a weather forecast on October 7th predicting that the eastern portion of Hainan Island will experience significant precipitation from October 8th to 9th due to the influence of an easterly jet stream, with localized areas facing torrential rainfall 1. Wind conditions are expected to intensify across maritime regions, with the Qiongzhou Strait and waters near the South China Sea experiencing winds of 5 to 6 levels, gusting to 7 to 8 levels during thunderstorms 1. The Beibu Gulf and seas near the Xisha and Zhongsha island groups are forecast to see wind speeds of 5 to 6 levels and gusts of 7 to 8 levels, with thunderstorm gusts potentially reaching 9 levels 1.

The meteorological authorities have recommended that relevant departments conduct thorough inspections of reservoirs, implement defenses against urban and rural waterlogging, monitor medium and small rivers for flooding risks, and prepare for potential landslides and geological disasters 1. Given that September rainfall in Hainan Island exceeded the historical average by approximately 20 percent, resulting in elevated soil saturation levels across certain municipalities and counties, the approaching heavy rainfall carries heightened risks of road and bridge subsidence or collapse 1. Enhanced surveillance of roads and bridges is critical under these conditions 1.
