"The flood rose very fast, flooding the eaves in front of the house in less than an hour." A few days ago, in Chenjiahe Town, Sangzhi County, Hunan Province, villager Mao Mingyong told reporters, "That day, fortunately, I ran in time. ”
From 18:35 to 20:20 on June 27, the cumulative precipitation in Chenjiahe Town, Sangzhi County exceeded 100 mm, and the county meteorological station issued a red warning of heavy rainfall to 1,696 people in Chenjiahe Town at 19:26.
Like Mao Mingyong, many people "ran" after receiving accurate targeted meteorological warning information for the first time.
According to the statistics of the Hunan Provincial Flood Control and Drought Control Headquarters, the round of heavy rainfall that began on June 27 caused a total of 1.2546 million people to be affected, 100 geological disasters occurred, and the government urgently resettled 49,000 people, successfully achieving zero casualties, and accurately targeting early warning information played a key role in this emergency response.
In the round of heavy rainfall that began on June 27 this year, the Meteorological Department of Hunan Province, together with the three major communication operators, issued 397 warning information (as of 8 o'clock on July 5) to the public in "local areas", including 88 counties with red warning signals for heavy rain and 309 township (town) warnings for heavy rainfall in townships, covering a total of 25.84 million person-times.
Progressive meteorological early warning service is a service jointly carried out by the meteorological departments of Hunan Province, cities and counties in recent years. In the process of responding to heavy precipitation weather: 3 days in advance, the provincial, municipal and county three-level meteorological departments jointly issued important warning information for the weather process, focusing on reminding the three-level government flood prevention responsible persons to make work arrangements in advance.
One day in advance, the provincial meteorological department issued early warnings such as heavy rain and strong convection, focusing on reminding cities and counties to arrange flood prevention duty and hidden danger investigation.
3 to 6 hours in advance, the city and county meteorological departments issued an early warning, focusing on reminding the county and rural areas to carry out patrols and defenses.
One hour in advance, the county-level meteorological department issued a township disaster warning containing heavy rainfall warnings and short-term warnings of geological disaster meteorological risks, focusing on reminding the rural organizations to avoid danger and transfer.
Progressive services have rules to follow, and targeted early warnings also match standards. At the designated time and in the designated area, when there is a red warning signal for heavy rain, a hail warning signal, a thunderstorm and gale monitoring alarm, a red disaster warning for heavy rainfall in townships, a red warning for urban waterlogging risk, and other major emergency information, the targeted warning will definitely be targeted.
If someone is within the above warning or warning level and conditions, they will be enclosed in the electronic fence of the "Provincial, Municipal and County Meteorological Disaster Early Warning Service Integration Platform". High-impact level early warning signals, disaster warnings, etc., will be directly direct.
"In the past, the 'local area' in the weather forecast often became the object of public ridicule, and the 'local area' often corresponded to the point where the disaster was most serious - such as heavy rain in the local area and heavy rain in the local area. The target of the accurate target early warning information is for people in the 'local area', which can be said to eliminate the doubts in people's minds in the past to a certain extent. Liu Ruiqi, director of the Hunan Meteorological Service Center, said that as long as the meteorological early warning information is accurately released to the public in the electronic fence and the early warning dissemination link is reduced, the audience can achieve "second reception" and the early warning timeliness is further improved.
