Experts said that monitoring data showed that from yesterday (17th) to this morning (18th), the rain was still mainly in southwest and south China; Among them, short-term heavy rainfall occurred in Yunnan, Hainan and other places. According to the analysis of the latest meteorological data, starting today, the warm and humid airflow will strengthen and move northward. According to the numerical model forecast of 850 hPa pseudo-equivalent potential temperature, the area of the 340K line moves northward with the southerly wind; Moreover, the atmospheric precipitation in the coastal areas of South China exceeds 70 mm; This shows that the low-altitude atmosphere is hot and humid, with sufficient water vapor and energy, and is prone to heavy rainfall. For this reason, the Central Meteorological Observatory this morning continued to issue a blue warning for heavy rain.

The Central Meteorological Observatory predicts that from 08:00 on May 18 to 08:00 on the 19th, there will be heavy to heavy rain in parts of southwest Guizhou, Guangxi, western and southern coasts of Guangdong, and northern Hainan Island; Among them, there are heavy rainstorms (100~120 mm) in southeastern Guangxi and other places. From the day of the 19th to the morning of the 20th, the center of heavy rainfall gradually shifted from Guangxi to Guangdong.

It is worth noting that industry insiders emphasized that it is not difficult to find that the situation is also not difficult to find, as experts said, by the 20th, the heavy rainfall in the south continued to move eastward; At that time, the core area will move eastward to the Pearl River Estuary to the eastern part of Guangdong and Fujian. In addition, there was also a precipitation process in Northeast China and North China from the morning of the 18th to the 20th. Because there is also convective energy at low altitude, but the water vapor conditions are relatively poor; Therefore, the strong convection may be dominated by thunderstorms and high winds.
