According to the National Center for Hydro-Meteorological Forecasting, the low pressure trough with an axis at about 24 - 26 degrees north latitude was compressed, pushing the movement south by the continental high pressure in the north.
In the evening and night of June 2, the Northern region is forecast to have showers and thunderstorms, locally heavy rain with rainfall of 20 - 40mm, locally over 70mm. In mountainous and midland areas, there were some places with very heavy rain over 150mm.
The meteorological agency warns that there is a risk of heavy rain (rainfall greater than 100mm within 3 hours). During thunderstorms, there is a possibility of tornadoes, lightning, hail and strong gusts of wind. Localized heavy rains are likely to cause flash floods on small rivers and streams, landslides on steep slopes and flooding in low-lying areas. The warning level of natural disaster risk due to tornadoes, lightning, and hail is level 1.
Regarding the trend of rain in June, the predictive meteorological agency, the total rainfall across the country is approximately the average of the same period; Particularly in the North Central region, the total common rainfall is higher than the average of the same period from 15-25%.
During the forecast period, the Northern and North Central regions will likely experience some widespread heavy rains.
In the Central Highlands and the South, the southwest monsoon tends to get stronger, so the rain is likely to increase in both area and rainfall.
On a national scale, there is a continued possibility of dangerous weather phenomena such as thunderstorms, tornadoes, lightning, hail and strong gusts of wind.
The phenomenon of heavy rain and thunderstorms, whirlwinds, and lightning can negatively affect production activities and public health. In particular, beware of localized heavy rains that can cause floods, inundation in low-lying areas and landslides in mountainous areas.
