Beware of extreme weather from now until the end of 2025

According to the Dong Nai Province Hydrometeorological Station, from now until the end of 2025, in Dong Nai, dangerous weather phenomena such as thunderstorms, tornadoes, lightning, hail, localized heavy rain, and unusually heavy rain are likely to occur during the rainy season months. It is necessary to be on guard against strong southwest monsoons causing widespread heavy rain.

Flood peak is likely to occur in July and August.

Director of Dong Nai Province Hydrometeorological Station Nguyen Phuoc Huy noted that from now until the end of 2025, the phenomena of thunderstorms, tornadoes, lightning, localized heavy rain, and unusual heavy rain are likely to continue to appear frequently in the province. The average temperature from now until the end of 2025 is approximately equal to or higher than the average of many years. The total rainfall in July and August 2025 is less than or equal to the average of many years, commonly from 250-350mm. In September 2025, the total monthly rainfall is approximately equal to or higher than the average of many years, commonly from 310-400mm.

The water level on the Dong Nai River system at Ta Lai Station will gradually increase in the coming time. The highest flood peak of the year is likely to appear in July and August 2025, at a level higher than the alarm level 2 (112.5m); at Tri An Lake, the lowest water level tends to appear in July, then gradually increase, lower than the average of many years. In the lower reaches of the Dong Nai River, at Bien Hoa Station, the highest peak water level is approximately at the alarm level 2 (2m), appearing in September, higher than the average of many years; the water level at the foot of low tide gradually increases, lower than the average of many years.

Water levels on the La Nga River system in Phu Hiep are gradually rising. The highest flood peak of the year is likely to occur in August, at approximately alert level 2 (105.5m).

It is necessary to proactively guard against dangerous hydrological phenomena such as: rapid and sudden floods on major rivers when there is heavy rain upstream due to the influence of storms, tropical depressions or due to flood discharge from upstream reservoirs. Beware of localized flooding in urban areas, low-lying areas; flash floods in small rivers and streams; landslides in mountainous areas when there is heavy rain. Floods, inundation, flash floods, and landslides pose a risk to human life and property, causing traffic jams and negative impacts on the socio -economy.

More than 9 storms/tropical depressions appear in the East Sea

Dong Nai Province Hydrometeorological Station forecasts that from now until the end of 2025, there is a possibility of many storms or tropical depressions appearing in the East Sea affecting our country and possibly making landfall. It is forecasted that from now until September 2025, there is a possibility of 5-7 storms or tropical depressions appearing in the East Sea affecting our country and possibly making landfall 2-3 times. Along with that, phenomena such as thunderstorms, tornadoes, lightning, hail, and strong gusts of wind continue to appear over a wide area. In Dong Nai, there is a possibility of continued heavy localized rain and unusually heavy rain.

From October to December 2025, there is a possibility of 4-6 storms or tropical depressions appearing in the East Sea, of which about 2-3 will make landfall in our country, indirectly affecting the weather in the province. There is a possibility that unusually heavy rain will still appear in October. "Storms and tropical depressions operating in the East Sea usually do not directly affect the weather in the province. However, the circulation of these storms and tropical depressions is likely to impact, combined with disturbances in the atmosphere, to strengthen the southwest monsoon, causing heavy rain in the province," said Mr. Nguyen Phuoc Huy.

It is forecasted that the water level in the upper Dong Nai River at Ta Lai Station will change slowly in October; gradually decrease in November and December; and continue to increase gradually at Tri An Lake. In the lower Dong Nai River, at Bien Hoa Station, the highest peak tide level of the year is likely to occur in October 2025, at a level higher than alert level 2 (2m), higher than the average of many years; the low tide tends to decrease again, lower than the average of many years.

Water level on La Nga river system at Phu Hiep changes slowly in October; gradually decreases in November and December.

From October 2025, water levels in rivers and streams will gradually decrease, but remain high. Local flooding in urban areas and low-lying areas during heavy rains must still be prevented. Flash floods in small rivers and streams; landslides in mountainous areas; local flooding during heavy rains affect socio-economic activities, human life; and the growth of crops and livestock.

Director of Dong Nai Province Hydrometeorological Station Nguyen Phuoc Huy warned people and authorities to proactively guard against extreme weather phenomena that can impact the environment, living conditions, infrastructure, and socio-economic activities such as storms, tropical depressions, thunderstorms, tornadoes, lightning, hail, heavy rain, etc. that can cause danger to people and damage property; and cause difficulties for life, daily activities, and agricultural and aquaculture production.
