In the next 24-48 hours, the hot low pressure area in the West will continue to weaken. The low pressure trough with the Northwest - Southeast axis passing through the South Central Coast and the South will still be maintained but will gradually weaken.
Above, the subtropical high pressure with its axis through the South East Sea is operating stably, then gradually strengthens and shifts its axis northward. Southwest winds in the Southern sea area maintain weak intensity.
From 3-10 days, the hot low pressure area in the West tends to develop and gradually expand eastward. The subtropical high pressure above has a tendency to encroach westward again, with its axis passing through the South Central - Southern region and then gradually rising to the Central and Northern regions.
Around May 26-27, this system weakens and continues to shift its axis to the North. Southwest winds over the Southern sea areas operate at a weak to moderate level. Notably, around May 27-28, a low pressure trough is likely to form passing through the central and southern areas of the East Sea.
Due to the impact of the above weather patterns, on the day and night of May 21, the Southern region experienced moderate to heavy rain with scattered thunderstorms, common rainfall of 20 - 40 mm, locally over 100 mm. During the thunderstorm, there is a possibility of tornadoes, lightning, hail and strong gusts of wind, posing a potential risk of affecting agricultural production, breaking and collapsing green trees, damaging houses, traffic and infrastructure works.
From May 23, hot weather tends to increase again, while rain gradually decreases.
