Meteorologists said.
Rainy weather has adverse effects on transportation, forestry and water conservancy.
On the morning of March 7, Jiangxi Meteorological Bureau organized a meeting of meteorological disaster linkage departments to analyze the impact of continuous rainy weather and preventive measures.
The reporter was informed that the continuous rainy weather led to insufficient power supply at the video monitoring points of the expressway, especially at important sections and bridges. At the same time, due to poor visibility in rainy weather, the incidence of traffic accidents has increased; Rainy weather also affects the progress of afforestation construction, and trees are prone to decay and the incidence rate is high; In addition, the road surface is slippery, and the number of trauma and respiratory tract patients increases, which has a great impact on the emergency response of emergency vehicles, the timely transfer rate of patients, patient visits, home service, etc. 1 Up to March this year, geological disasters occurred in Jiangxi * * 10, of which 4 were caused by rainfall; Continuous rainy weather is unfavorable to the construction of water conservancy projects and small and medium-sized river basins, which has a great impact; The water level of the river rises rapidly. Since June+10, 5438, ultra-warning water levels have appeared in Xinjiang, Wan 'an and Ganzhou. Poor drainage and long-term saturation in dry land, abnormal development of crop roots and plants, affecting yield and quality, resulting in waterlogging and wet damage.
Cloudy and sunny over the weekend, it will rain again on June 5438+04.
According to the analysis of current meteorological data, Jiangxi Meteorological Observatory still maintained rainy weather before March 10. Due to the adjustment of circulation situation, it will all turn into process weather after March 10.

Meteorologists reminded that due to the rainy weather in the west of Jiangxi before March 10, there will be a precipitation process around March 15, and all localities should strengthen the monitoring and dispatching of dangerous reservoirs and the inspection of geological disaster-prone areas, mining tailings ponds and small and medium-sized rivers to prevent the adverse effects caused by local heavy precipitation. On March 1 1-12, there may be heavy fog in some places in Jiangxi. The transportation department should strengthen road control and drivers should drive carefully.
In addition, rape, green manure, vegetables and other crops in the field should be cleaned and drained in time. After the rain stops, the crops in the shed should be properly opened or ventilated to reduce the humidity. Crops in the shed should be ploughed and replanted after serious seedling death due to continuous rain. After the weather clears in the early rice planting area, the seeds should be dried in time. In areas where late-maturing varieties are used in southern Jiangxi and central Jiangxi, seeds can be soaked to accelerate germination in about 15 days. After the precipitation process is over, you can keep warm and plant seedlings.
