Weather pattern forecast for the next 24-48 hours, the intertropical convergence zone has an axis of about 13-16 degrees North latitude, connected to a tropical depression. This system moves mainly in the Northwest direction and around the morning of September 14, it is likely to enter the mainland area from Ha Tinh to Quang Tri, then weaken.
Southwest monsoon is active with moderate intensity. Wind convergence is operating well in the area in the next 24 hours, then moves westward and weakens. Above, the southern branch of subtropical high pressure tends to encroach westward, with its axis passing through the South China Sea area.
Weather pattern forecast from 3-10 days, the intertropical convergence zone has its axis through the Central Central region, then raises its axis to the North and operates weakly. From about September 17-18, the intertropical convergence zone will lower its axis to the South, with its axis through the South Central and Southern regions, and at the same time tend to become stronger. Southwest monsoon maintains medium intensity.
Above, the southern branch of the subtropical high pressure continues to encroach westward, with its axis through the South China Sea. From around September 17, the southern branch of the subtropical high pressure will weaken, while the northern branch will strongly encroach westward.
Also from around September 17, wind convergence is likely to resume in the Southern region. Therefore, the Southern region is likely to experience increased thunderstorms, accompanied by the risk of tornadoes, lightning and strong gusts of wind.
Dangerous weather phenomena can cause trees to fall, damage houses, traffic works and infrastructure, affecting agricultural production and people's lives. Heavy rain can cause flooding, traffic jams, affecting production, travel and daily life. It is noteworthy that heavy rain is likely to occur between September 18-20.
