Due to the impact of the hot low pressure area from the West expanding to the Southeast combined with the increasing pressure part moving down from the North, the low pressure trough with the Northwest - Southeast axis crosses the North and descends to the Southeast East Sea area. Above, the subtropical high pressure maintains its axis through the South - South Central Coast with stable intensity. In the South Sea area, the Southwest wind is weak.
In the next 3-10 days, the low pressure trough will continue to be maintained in the Northwest - Southeast direction through the South Central region. Southwest winds over the Southern sea area from about May 19-20 tend to gradually become stronger.
Above, the subtropical high pressure with its axis through the South Central Coast weakens and gradually recedes southward; by about May 23-24, the subtropical high pressure is likely to encroach westward again, with its axis passing through the South Central Coast and the South.
Due to the influence of the above weather patterns, in the coming days, the Southern region is likely to experience scattered showers and thunderstorms in the afternoon and night, with locally heavy rain.
In thunderstorms, it is necessary to be wary of tornadoes, lightning, hail and strong gusts of wind, which can affect agricultural production, break down trees, damage houses, traffic and infrastructure works.
