The Northern region is currently experiencing heavy rainfall due to the impact of a weakened low-pressure area from Typhoon No. 3 (Typhoon Yagi), combined with a tropical convergence zone forming in the North. Over the past two days, intense rainfall has covered the midland and mountainous areas of the North with particularly high precipitation levels.
From 7 PM on September 8 to 3 PM on September 9, rainfall measurements recorded 481mm in Tan Phuong (Yen Bai) and 451.2mm in Nam Dan (Ha Giang). Many other provinces, such as Thai Nguyen, Lao Cai, Quang Ninh, Lang Son, Cao Bang, and Tuyen Quang, have reported rainfall exceeding 200mm in less than a day.
Due to the prolonged heavy rain combined with hydropower dam discharges, water levels are rising rapidly in the rivers.
In Hanoi, from the afternoon of September 9 to the morning of September 10, heavy rains have also caused many low-lying roads to become flooded.
Given the ongoing heavy rains and flooding in many areas, residents are advised to closely monitor news through television, radio, and official information channels. In addition, there are several other precautions that the public should particularly heed to protect their lives and health during this flooding.

1 Thing to Avoid During Floods
In 2020, the World Health Organization (WHO) published guidelines for health protection during floods. Accordingly, the WHO recommends that people avoid walking or driving through flooded areas.
“Even the smallest amount of water can pose significant dangers,” the WHO states. “You cannot know if power lines have fallen into the water or if there are hazardous chemicals present. Vehicles and people can easily be swept away in floodwaters.”
The U.S. National Weather Service issued similar warnings. “Do not walk or drive through flooded areas.”
“Just 15cm of flowing water can knock you over. If you become trapped in flowing water, move to higher ground and call for help if possible.”
“Do not drive into flooded roads or around barricades; turn back! Water may be deeper than it appears and may conceal dangers such as sharp objects, washed-out road surfaces, downed electrical lines, and chemicals.”
The U.S. National Weather Service also warns of the dangers of driving into floodwaters. “A car trapped in fast-moving water can be swept away in seconds. Water that is 30cm deep can float a small car or SUV, while 46cm can sweep away larger vehicles.”
Other Precautions to Protect Health During Floods
According to the WHO, as flooding can increase the risk of transmitting various diseases, it is crucial to be aware of the risks and protect water sources. The most common risks associated with flooding include contamination of drinking water supplies; stagnant water becoming a breeding ground for mosquitoes; and chemical and injury hazards.
Therefore, in addition to avoiding flooded areas, you should also pay attention to the following:
- Know the evacuation routes and local warning signals, and identify areas prone to flooding or landslides.
- Disinfect or boil all drinking water and water used for cooking.
Ensuring a continuous supply of safe drinking water is the most important preventive measure to take after flooding to reduce the risk of waterborne disease outbreaks.
Do not drive into flooded roads or around barricades.
- Encourage safe food hygiene and preparation practices.
Do not use floodwater for washing dishes, brushing teeth, or washing and preparing food. Always wash your hands with soap and clean water if you have been in contact with floodwater.
- Dispose of any food that has come into contact with floodwater.
If food has been exposed to floodwater, it is unsafe to eat and increases the risk of waterborne diseases.
- Clean your home if it has been exposed to floodwater.
Dispose of any items that cannot be washed and sanitized with bleach, such as pillows and mattresses. Clean all walls, floors, and other surfaces with soap and water, as well as bleach.
- Control mosquitoes.
If your home is in an area with stagnant water, use mosquito repellent, following the instructions on the packaging, and apply it to clothing or skin. Additionally, wear long pants and long-sleeved shirts, and use a mosquito net while sleeping.
