The meteorological department of Hainan Province reminded
(1) Due to the heavy accumulated rainfall in the early stage in the eastern half of Hainan Island, the soil moisture in some areas was close to saturation, and there was continuous heavy precipitation in the eastern half of Hainan Island from 22nd to 24th. Relevant departments need to continue to take precautions against secondary disasters such as farmland waterlogging, mountain torrents, floods in small and medium-sized rivers and geological disasters in this area, and strengthen risk prevention such as floodbridges, floodways and mountain roads.
(II) Cities are prone to waterlogging risk, so it is necessary to pay special attention to the safety of underground facilities such as underground garages and underpasses, strengthen risk prevention in high-risk areas such as dangerous houses, slopes, simple sheds, rivers and hidden danger points of geological disasters, and strengthen supervision and hidden danger investigation in key places such as tourist attractions and construction sites.
(3) It is necessary to strengthen the inspection of reservoirs, pay attention to the limited water level of reservoirs in flood season, and pre-discharge measures can be taken in time for high-level reservoirs.
(4) Harvest mature late rice in time to prevent grain germination and rot caused by precipitation. After the rainstorm, the fields that plan to plant melons and vegetables will be drained in time to prepare for cultivation. Early-maturing litchi is easy to shoot autumn shoots after multiple rounds of precipitation, so fruit farmers should do a good job in controlling the shoots.
