Abstract: The "Opinions on Strengthening the collaboration of Meteorological Early Warning and Emergency Response" jointly issued by the Ministry of Emergency Management of China and China Meteorological Administration is of great practical significance for improving the ability of grass-roots governments to prevent and respond to rainstorm, typhoon and strong convective weather. Through the tracking and analysis of 48 rainstorm red early warnings of rainstorm in 39 counties (cities, districts) and 5 flood emergency responses in 4 counties (cities, districts) in Zhejiang Province from August to September, 2022, and the communication and discussion with a number of front-line flood prevention staffs at the grass-roots level, it is found that there were several problems existed including too frequent responses, more delayed responses, and greater inaccurate response ranges during the implementation of the "Opinions". This paper finally gives suggestions on revising the rainstorm early warning threshold, optimizing response measures, and refining the response range.
