Mr. Hoang Phuc Lam exchanged information about storm No. 3 Wipha.

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.
