Explaining the reason for the storm's landfall, some places are still sunny
On the afternoon of July 22, Mr. Mai Van Khiem - Director of the National Center for Hydro-Meteorological Forecasting provided updated forecast information on the impact of storm No. 3 Wipha.

"From the afternoon of July 22 to the morning of July 23, Thanh Hoa, Nghe An, the south of Phu Tho and Son La will be the focus of heavy rain. These areas have heavy to very heavy rain and thunderstorms with common rainfall of 60-120mm, locally over 200mm" - Mr. Khiem said.
According to Mr. Khiem, other places in the Northern region and Ha Tinh will have rain, moderate rain, locally heavy rain and thunderstorms with rainfall of 20-40mm, locally over 100mm. Warning of the risk of heavy rain with rainfall greater than 150mm within 3 hours.
"Heavy rain increases the risk of flash floods on small rivers and streams and landslides on steep slopes in mountainous and midland areas; especially pay attention to the mountainous communes in the west of Thanh Hoa and Nghe An provinces, south of Phu Tho and Son La" - Mr. Khiem warned.
Today, July 22, Mr. Hoang Phuc Lam - Deputy Director of the National Center for Hydro-Meteorological Forecasting also explained the uneven rain distribution, heavy rain in places and sunlight in places, despite all being affected by the storm's circulation.

According to Mr. Lam, in a storm or weather cloud system, not all cloud areas are likely to cause rain, because there may be many different types of clouds. For example, high-level clouds often only cover the sun. Therefore, there are areas where even though they are covered with clouds, there is still no rain, or sometimes the rain is interrupted and then stops.
"Even in a hurricane circulation system, differences in rainfall, strong winds and danger levels are common. Some places have gusts of level 89, causing roofs to blown off and trees to fall; some places are just cloudy, no rain and even light sunshine" - Mr. Lam analyzed.
Storm No. 3 has the characteristics of thunderstorms causing rain concentrated to the south, so the southern circulating provinces such as Thanh Hoa and Nghe An have recorded heavier rainfall.
Meanwhile, localities located in the northern part of the storm's circulation such as Hanoi and the Northeast region have gradually decreased in rain compared to the day and night of July 21.
However, a representative of the meteorological agency warned that the rain will continue but there may be interruptions.
