Introduction: Today is February 3rd, today and tomorrow, the strongest moment of this round of heavy rain and snow has arrived, and on February 5th, the main battlefield of this round of heavy rain and snow in the central and eastern regions of the heavy rain and snow has withdrawn from the battle on a large scale, but from February 3rd to February 4th, the freezing rain area has an expanding trend, and everyone must pay attention to safety when returning!
With the continuous force of this round of heavy rainfall and snowfall, the heavy snowfall in Henan has not stopped intermittently since the night of January 31, and some areas in Anhui, Shaanxi and other places have also joined the snowfall family on February 1, and the entire central and eastern regions have become snowfall areas.
This has brought great inconvenience to the traffic, some high-speed toll stations in Henan, Shaanxi and other places have been closed, and the number of trains has been reduced or adjusted, which has brought a great adverse impact on everyone's return.
And just today, the Blizzard Orange Warning and the Freezing Orange Warning were issued at the same time, and the blizzard in the central and eastern regions will continue, and the freezing rain areas in Central and East China have ushered in the strongest moment.
It can be seen from the blizzard warning that this round of heavy snowfall continues to move southward, and has introduced the snowfall area to the Hunan and Sichuan basins, and even to enter the Guizhou region, which is too terrible, which shows that this round of cold air is not so fragile, and has now advanced into the middle and lower reaches of the Yangtze River.
It can be seen from the meteorological map that the main heavy snowfall area on February 3 has moved southward to parts of Anhui, Hubei, Hunan and other places, of which the maximum cumulative snowfall has reached 31 mm, which is more than 40 cm when converted into snow thickness, which is the cumulative value of this round of heavy snowfall.
Another kind of weather is more worthy of everyone's attention, that is, the freezing rain belt in the rain and snow conversion area, just yesterday the Wuhan area has begun to rain freezing, the impact of freezing rain on road safety is much higher than that of blizzard, the freezing rain is the southwesternmost to Guizhou, the northeast to Jiangsu, it can be said that the scope is particularly wide, directly dividing Central China and East China into two, seriously affecting everyone's travel.
By February 4, the current round of precipitation and snow collectively moved to the east, especially in the heavy rainfall areas in the south, mainly in Jiangxi, Zhejiang, Jiangsu, Shanghai and other places, of which the maximum cumulative rainfall reached 55 cm.
With the eastward shift of the precipitation and snow areas, the scope of the frozen rain belt has also converged a lot, and the southwest of Guizhou and Chongqing gradually withdrew, and the frozen rain belt began to shrink from the southwest to the northeast.
This is because the cold air from the north and the water vapor and warm air from the southern branch trough from the south collided, and then started to the east and unloaded into the sea, so that the main snowfall area in the north will slowly disappear on February 5.
In the next two days, the cold air will push the 0 freezing line back to the north of South China, which will make Central and East China return to the cold moment, and the only thing to be thankful for is that with the cold air going south, the humid and hot weather in South China will ease down, the temperature is not so high, and the return to the south can end early.
Today is the twenty-fourth day of the lunar month, the small year in the south, and now there are only 6 days left before the New Year, and at this time, the heavy rainfall is still on the rise, and it has to last for two days, which will rain the heavy snowfall to the twenty-fifth day of the lunar month.
At present, some areas in Henan, Shaanxi, Hubei and other regions have been closed to high-speed toll stations and road closures, and in Guangdong and other South China regions, there is also a situation of high-speed congestion, so when setting off, you must look at the road conditions, and try to detour as much as possible.
For the freezing rain area, especially in Hubei, everyone must pay attention to the weather changes in advance and try to avoid the freezing rain area to prevent adverse effects on the way home.
