According to the Center for Hydrometeorology, subtropical high pressure is now spreading to the west. The low pressure trough has an axis at about 4-7 degrees North latitude.
In the next 2 days, the North will be affected by the weakening of the continental cold high pressure blade. Illustration
Due to the influence of the East wind zone from the edge of the subtropical high pressure extending to the West, from now to April 6, the area from Thua Thien Hue to Khanh Hoa experiences moderate rain, heavy rain and thunderstorms.
In addition, due to the influence of the northern edge of the low-pressure trench analyzed above, from now to April 6, the Central and Southern Highlands experience rain and thunderstorms, with moderate to heavy local rain with 30-60mm/day of 24-hour rainfall, some places more than 70 mm/24 hours (rain time is concentrated in the afternoon and evening).
During a thunderstorm, there are chances of tornadoes, lightning, hail and strong winds. The risk of flash floods and landslides in the area Plateau and local flooding in low-lying, low-lying areas along rivers.
In the next 2 days, the North will be affected by the weakening of the continental cold high pressure blade; pressure decreases, humidity increases. The south is influenced by the southwest edge of this continental cold high pressure blade combined with the East wind zone on the south edge of the subtropical high pressure analyzed above; in particular, the South is affected in combination with the northern edge of the low-pressure trough with the axis around 4-7 degrees North latitude, gradually raising the axis to the North; pressure and humidity increase.
In the following days, in the North there was light rain in some places at night, on foggy mornings, on clear days. Night and early morning it’s cold.
The area from Thanh Hoa to Thua Thien Hue has light rain in some places, sunny in the afternoon and evening; In the south, there was rain on the nights of April 4 and April 5, heavy rain, moderate rain in Thua Thien Hue, heavy rain and thunderstorms in some places. Cold nights and clear morning skies.
The area from Da Nang to Binh Thuan has seen torrential rain and thunderstorms, with moderate and heavy rains locally; In particular, the area from Da Nang to Khanh Hoa had moderate, heavy rain from the night of April 4 to 5.
The Central and Southern Highlands experience rain and thunderstorms in some places, in the afternoon and evening rain and scattered thunderstorms, with moderate and heavy rain locally.
During a thunderstorm, there is a chance of thunderstorms, hail and strong winds.
From April 6-14, the cold high pressure of the continent continued to move East and weakened. In the last 1-2 days, the western low pressure area tends to develop and gradually expands to the east.
In the south, the low pressure trough has an axis at about 5-8 degrees North latitude with a low eddy that is likely to form in the middle of the East Sea starting around April 8th.
Above, the subtropical high pressure will continue to strengthen towards the West, starting April 7th weakening and retreating to the East.
