Concerns and suggestions
The Henan Meteorological Service Center pointed out that due to the influence of the typhoon "fireworks" peripheral cloud system and the low trough of the westerly zone, heavy rains and local heavy rains will occur in the eastern and northern parts of Henan Province. As Henan Province was affected by extreme heavy rainfall in the early stage and the disasters were severe, attention should be paid :
——The impact of local heavy rainfall in the northern region on the Zhangwei River Basin and small and medium-sized reservoirs.
——The Jialu River Basin is currently discharging floods, and heavy rains in the east will increase the pressure of flood discharging.
-Mountainous areas need to guard against geological disasters such as mountain torrents and mudslides that may be caused by local heavy rainfall.
The Henan Meteorological Service Center stated that there is still some uncertainty in the path of the typhoon "Fireworks" after landing, and will pay close attention to its trends, strengthen monitoring and early warning, and provide timely services.
