The strongest rainfall since the flood season in North China will reach its peak, wide range of influence and high intensity
The last round of strong convective weather has not gone too far, and a new round of heavy precipitation has already played its part in the northern region, and this round of heavy precipitation cannot be underestimated.
The Central Meteorological Observatory predicts that from the night of the 11th to the 13th, there will be a heavy rainfall in the eastern part of Northwest China, North China, Northeast China, Huanghuai and other places. There will be heavy to heavy rains in some areas and heavy rains locally. From 20 o'clock on August 11th to 20 o'clock on the 12th, some areas in western Inner Mongolia, Ningxia, southern Gansu, southwestern Shaanxi, central and western Sichuan Basin, central and southern Hebei, Beijing, northern Tianjin, western Shandong, northern Henan, etc. In heavy rain, the above areas are accompanied by strong convective weather such as short-term heavy rainfall, thunderstorms, gales or hail. The Central Meteorological Observatory will continue to issue a yellow rainstorm warning at 18:00 on August 11.
Zhang Tao, chief forecaster of the Central Meteorological Observatory, analyzed on the 11th that the current round of rainfall has the characteristics of wide impact, strong intensity, and moving from west to east. This round of heavy rainfall began on the 10th in Gansu, Ningxia, and Shaanxi, and expanded to Shanxi and Hebei, and reached Liaoning and other northeastern regions on the 13th. The local daily rainfall in the Beijing-Tianjin-Hebei region does not rule out that it will reach more than 200 mm. This process It is the strongest precipitation since the flood season in the areas around Beijing-Tianjin-Hebei and Liaoning this year.
Taking Beijing as an example, the main rainfall period in the city is from noon to night on the 12th, and the rain gradually weakened and ended on the 13th. The average rainfall in the city is expected to be 40-80 mm, and the local area along the western and northern mountains may reach more than 200 mm, the maximum hour The rain intensity can reach 80-100 mm, and thunder and lightning and local short-term strong winds are accompanied during the rain. The Beijing Meteorological Observatory issued a yellow rainstorm warning signal at 17:40 on August 11.

Three early warnings are issued! Mountain torrent geological disasters have high meteorological risk
Under the influence of heavy rainfall, the risks of geological disasters and mountain torrents have also greatly increased. At present, meteorological risk warnings for floods in small and medium-sized rivers, meteorological warnings for mountain torrents, and meteorological risk warnings for geological disasters are being issued.
From the perspective of the range of early warning areas, the Sichuan Basin and southwestern Beijing need to focus on preventing various meteorological disasters.
The Central Meteorological Observatory has issued a meteorological risk warning for floods in small and medium-sized rivers at 18:00 on August 11th: Affected by rainfall, it is estimated that from 20:00 on August 11 to 20:00 on August 12, parts of western Hebei, southwest Beijing, western Sichuan Basin and other places The meteorological risk of flooding in small and medium rivers is high (yellow warning). Among them, the meteorological risk of flooding in small and medium rivers in some areas of the Sichuan Basin is very high (red warning).
At the same time, the Ministry of Water Resources and the China Meteorological Administration jointly issued a red flash flood disaster meteorological warning at 18:00 on August 11: It is expected that flash floods will occur in some areas of central and northern Sichuan and southern Gansu from 20:00 on August 11 to 20:00 on August 12 The possibility of disaster is high (orange warning), and the possibility of local mountain flood disasters in central Sichuan is very high (red warning).
The Ministry of Natural Resources and the China Meteorological Administration also jointly issued a meteorological risk warning for geological hazards at 18:00 on August 11: It is estimated that from 20:00 on August 11 to 20:00 on August 12, central and northern Sichuan, southern Gansu, and southwest Shaanxi , Southwest Beijing, Central Hebei and other places have higher meteorological risks (yellow warning) for geological disasters.
The Beijing Flood Control Headquarters issued a reminder on the 11th that there will be heavy rains in Beijing from morning to night on the 12th. It is recommended that all units implement flexible work systems and work from home. It is recommended that citizens reduce travel, park vehicles and pay attention to safety, and avoid mountainous areas, scenic spots, and rivers. Side and danger zone. It is recommended that the city stop construction on construction sites. The Beijing Municipal Planning and Natural Resources Commission and the Municipal Meteorological Bureau have jointly issued a yellow warning of meteorological risks for geological disasters at 20 o'clock on August 11. In the next 48 hours, the risk of geological disasters such as mudslides, collapses, and landslides in Beijing's mountainous areas will be higher.
Affected by the heavy rainfall, the official Weibo of the Badaling Great Wall and Yuanmingyuan Relic Park also released news that from 0:00 on the 12th to 24:00 on the 12th, the Badaling Great Wall, the Badaling Shuiguan Great Wall, the Badaling Ancient Great Wall and the Yuanmingyuan Relic Park will be temporarily closed. , Stop all tourist reception activities.

There will be another round of heavy rain in the north this weekend
Several consecutive strong convective weather made many netizens in the north wonder: Is this kind of weather normal?
Zhang Tao analyzed that since the beginning of this year, extreme weather such as heavy rainfall, drought and high temperature has occurred frequently. In fact, such weather occurs on a large scale in China every year. Affected by the movement of the main rain belt, Southern China, Jiangnan, and Northeast China will have strong Precipitation; and places controlled by the subtropical high will also face prolonged high temperature or drought, which is a long-term climate phenomenon.
However, the weather conditions this year have indeed been extreme. Compared with the average year-round conditions, they are in an abnormal direction. The final extent of the abnormality still needs to be evaluated, but judging from the flood situation in the early part of this year, it should be quite extreme.
Meteorological monitoring shows that there will be another precipitation process in the northern region from the 15th to the 17th of this month. It seems that the intensity is a little weaker, but there are also relatively large variables.
Experts remind the public that there are meteorological risks of mountain torrents and geological disasters in mountainous and shallow mountainous areas. Try to avoid going to dangerous areas, rivers, and areas with hidden geological disasters in mountainous areas, and raise awareness of secondary disasters and strong convective weather. Strong convective weather such as short-term heavy rainfall and strong winds will have an impact on urban operations, transportation, and agricultural production. The public should minimize travel and do not stay under tall buildings, billboards, temporary structures or large trees. (Finish)
