A cold front is coming again; be prepared for hailstorms.

According to the National Center for Meteorological and Hydrological Forecasting, around May 8-9 (approximately Friday-Saturday this week), another cold front will affect the North, leading to continued thunderstorms and the risk of tornadoes, hailstorms, and strong gusts of wind.

Around May 5-7, 2026, widespread showers and thunderstorms are likely to occur in the southern part of the Central Highlands and Southern Vietnam. The rain will be concentrated from afternoon to evening. During thunderstorms, be wary of tornadoes, lightning, hail, and strong gusts of wind.

In particular, there is a very high probability (80–90%) of El Niño occurring from mid-2026, potentially reaching very strong intensity by the end of the year (20–25%) and extending into 2027.

This year, hot weather is predicted to be more frequent and intense than average, with fewer rain and storms, but thunderstorms, tornadoes, hailstorms during the transitional season, and localized heavy rainfall may also occur more frequently.

Localized heavy rainfall of high intensity over a short period can cause flash floods, landslides, and urban flooding, especially in mountainous areas and steep terrain.

Signs to recognize when hailstorms occur.

Hail is a very small-scale phenomenon that often accompanies strong thunderstorms during transitional seasons. Hail is usually accompanied by fairly distinctive signs that people can proactively recognize, such as the appearance of developing storm clouds, a rapid change in temperature from hot and humid to cool, strong gusts of wind, and heavy rain accompanied by lightning. When these signs appear, people should quickly seek safe shelter, avoiding being outdoors or under large trees.
