Typhoon Noul weakens, widespread heavy rain hits Southern region

According to the National Center for Hydro-Meteorological Forecasting, storm Noul moved deep into southern mainland China on Sunday morning and no longer poses a direct threat to Vietnam.

However, meteorologists warned that the storm's circulation has altered wind patterns, triggering contrasting weather conditions between the Northern and Southern regions in the coming days.

The Southern region and the Central Highlands will remain the hardest-hit areas nationwide. Strengthening southwest monsoons are channeling substantial moisture from the western seas inland, fueling widespread downpours and thunderstorms. Several southern localities are expected to see rain starting as early as Sunday morning.

Precipitation is projected to intensify from noon through the afternoon and evening, with moderate to heavy rainfall in many areas. Ho Chi Minh City and provinces across the Southeastern region face an ongoing risk of heavy downpours in the late afternoon and evening.

Meanwhile, the Northern region has seen an end to its recent rainy spell, transitioning to clearer and drier conditions. Scattered showers remain confined to a few Northwestern provinces, including Lai Chau, Dien Bien, and parts of Lao Cai and Son La. The rest of the region will experience intermittent sunshine and hot, humid weather during the day.

In the Central area, scattered showers and thunderstorms are expected this afternoon and evening, primarily affecting the western areas stretching from Thanh Hoa to Quang Ngai provinces. Daytime will bring sunny conditions, with localized heatwaves in some areas.

Meteorological agencies forecast that rainfall will likely return to the North starting the night of July 27, driven by a newly developing low-pressure trough interacting with the remnants of storm Noul. From July 27 onward, mountainous and midland areas in the Northern region should brace for moderate to heavy rain accompanied by severe thunderstorms.
