Will the three early warnings issued by the Central Meteorological Observatory affect the second peak of Spring Festival travel rush’s return trip？

The first cold wave in the Year of the Loong came to an end today, and the Central Meteorological Observatory lifted the orange warning of cold wave and the snowstorm warning at 18: 00 on the 22nd. At the same time, however, the Central Meteorological Observatory issued a blue warning of strong wind, a yellow warning of low temperature and a yellow warning of freezing.

The Spring Festival holiday has passed. According to the forecast of the Ministry of Transport, the return passenger flow will have the second peak on February 25th (January 16th). Freezing rain, snow and freezing weather have a great impact on land traffic. Freezing rain and snowstorms in various places have caused high-speed rail to be delayed and highways to be congested or restricted. How will the weather develop in the second half of Spring Festival travel rush’s return trip?

High-speed control in many places in the south, delaying the start of school, and emergency closure of several scenic spots.

On February 20th, the first cold wave in the Year of the Loong and a wide range of rain, snow and freezing weather occurred in the central and eastern regions of China. It is worth noting that in this freezing rain and snow weather, freezing rain affects a wide range, and freezing rain has appeared in parts of Hunan, Hubei, central and northern Anhui and Henan. Freezing rain will cause the road to freeze, making it difficult for vehicles to drive and easily causing traffic accidents.

In these two days, Shandong Province ushered in the first cold wave in the Year of the Loong, with heavy snowstorms from west to east in southern Linyi, Liaocheng, Dezhou, Binzhou, Dongying and Jinan, which had a great impact on traffic. Before the snow, there appeared a "small ball" like snow but not snow, which was white and opaque and more "hit the floor" than snow. According to the local meteorological department, this is a relatively rare graupel.

In Hubei, graupel is mixed with rain, snow, freezing rain and ice particles, resulting in extremely complicated precipitation weather. On the morning of February 21st, several cars and motorcycles were trapped in Huanhu Road, Guanyinhu Scenic Area, Xiaochang County, Xiaogan City, Hubei Province. As of 15: 00 on February 22, many high-speed entrances such as Xingou Station of Hubei G0421 Xuguang Expressway and Hekou West to Xuanhuadian Section of G0424 Wuda Expressway were temporarily closed due to rain and snow.

Since the 20th, Hunan has experienced the strongest cold wave in the past 50 years. According to the Hunan Meteorological Bureau, 57 counties (cities, districts) including Huarong, Yueyang and Linxiang in the province have reached the standard of super cold wave. According to the monitoring of the meteorological department, from 7: 00 yesterday (21st) to 7: 00 today, due to the freezing rain, there were 11 cities (states) and 39 counties (cities, districts) with wire icing, the largest being Nanyue Station, which was 141 mm, followed by Hengshan Station, which was 4 mm.

According to local media reports, at 10: 00 am on the 21st, the traffic police in Ningxiang, Hunan Province released traffic information, and there was ice on the top of Jiuzhelun Mountain on Xiangwei Highway.

Yiyang announced that all kinds of schools (except the third grade of senior high school, where students have been reviewing) and other grades (including kindergartens) will be postponed until February 28 or 29.

Affected by the cold weather, some primary and secondary schools in Wuhu, Anhui Province have delayed school registration, and other schools have taken other forms such as online registration to carry out enrollment registration and other matters.

In addition, on the 21st and 22nd, due to the freezing rain and snow, Jiuhuashan Scenic Area, Tianzhu Mountain Scenic Area, Wanfoshan Scenic Area and many other scenic spots in Anhui Province were closed urgently.

Snow melting and deicing are uninterrupted, and traffic is guaranteed in Hubei and Hunan.

The reporter learned from the Hubei Meteorological Observatory that it is expected that the snowfall and freezing rain in Hubei will be maintained and the intensity will be weakened from the 23rd to 24th. In view of the fact that this round of low temperature, rain, snow and freezing weather will continue, which has caused congestion on many expressways, high traffic volume in Spring Festival travel rush, severe traffic situation and further development of the disaster, Hubei Provincial Emergency Management Department decided to upgrade the emergency response of low temperature, rain, snow and freezing disaster from level 4 to level 3 at 10: 00 on February 22.

By 12: 00 on February 21st, seven supervision teams in Hubei Province had supervised 464 key points, covering all 33 business units and 7,701 kilometers of expressways in the province. The province has assembled 6,539 emergency personnel, 41,949 tons of snow melting agent, 294 spreading equipment, 322 snow removing equipment, 100 snow removing and spreading machines, 127 graders, 191 deicers, 411 loaders and 988 other equipment.

According to public reports, Hubei Expressway has introduced an oil-fired steam road snow-removing and ice-melting vehicle, which is called "snow iron", which can realize "sucking while walking, stopping the vehicle to clear the snow" and carry out "hard-core" organization operations. In areas with severe snow and ice, the vehicles are used to work in echelon cycles in turn, which greatly improves the efficiency of snow shoveling and deicing and ensures smooth operation to the maximum extent.

Since February 20, there has been a large range of rain and snow cooling and blowing weather in Shaanxi. The transportation system of Shaanxi Province is fully engaged in anti-icing and snow removal, road traffic protection and service guarantee. In response to the impact of this special weather, Xi’ an Highway Bureau promptly warned and responded quickly according to the road conditions. By 11: 00 on the 21st, 46 snow removal machines, 47 tons of snow melting agent and 18 cubic meters of anti-skid materials had been dispatched.
