Facts about floods

Facts about floods

Floods are an overflow of water onto land that is usually dry.  In Malaysia, floods can occur in several ways. Monsoon floods, which is the most common type, develop over hours or days during the Northeast Monsoon when continuous heavy rain causes rivers to swell and overflow. Flash floods, especially in urban areas, occur suddenly after intense rainfall and often without warning. Coastal floods are caused by storm surges associated with tropical cyclones and tsunamis. Floods are predicted to become more frequent and severe due to climate change.

In Malaysia, floods are mainly caused by intense or prolonged rainfall especially during the Northeast Monsoon (November–March), when large volumes of rain fall over a short time and overwhelm rivers and drainage systems. Floods also occur when river levels rise beyond their capacity due to continuous rain, leading to overflow onto nearby floodplains. 

In urban areas like Kuala Lumpur, Penang or Johor Bahru, flash floods often happen because rapid development has replaced natural ground with concrete and asphalt, reducing the land’s ability to absorb rainwater. This causes water to accumulate quickly during heavy downpours. 

Coastal areas may also experience tidal flooding, which happens when high tides, storm surges, or strong winds push seawater inland—affecting states like Kedah, Kelantan, Sabah, and Sarawak. 

Although Malaysia does not have snowmelt floods, dam releases or dam-related incidents can contribute to downstream flooding, especially during extreme rainfall events.

Talk to your family about floods

Spend time together talking about floods and why they occur.

Practice your safety plan

Find a safe evacuation route to take in the event of a flood and practice it with your family. Talk together about having a meeting point in case you get separated. Create an “emergency kit” that includes non-perishable foods, medicines, a first aid kit, flashlight and batteries and water for several days in case you need to leave your area or services are cut off. Check with your child’s school and learn what the school’s plan is in case of a flood.

Know your risk

Learn about the kind of flooding that can take place in your community and identify the local emergency contacts you can reach out to if one occurs. Keep a close eye on forecasts from METMalaysia and real-time water-level updates from DID’s InfoBanjir portal. Familiarise yourself with your local alert system by knowing who provides warnings—such as NADMA, DID, and METMalaysia—and how these are broadcast through SMS alerts, radio, television, and social media.  

Save key numbers such as 999 for emergencies and NADMA’s Disaster Operations Centre (03-8064 2400) for disaster information. It is also important to know your home’s risk level by understanding whether you live near flood-prone rivers, low-lying areas, or rapidly developing urban zones that are vulnerable to flash floods. 

Teach children to swim

The majority of deaths that occur during floods are due to drowning.

Keep documents safe

Store any important papers like ID papers high up or in something that can protect against water damage (like a sealable plastic bag) to minimize the risk of damage. This includes documents like your IC/MyKad, passport, birth certificate, bank and insurance documents, land or property titles, and vehicle registration cards. Keeping these items protected will minimize the risk of damage during a flood.

Listen to local authorities

Tune in to your local news or radio station for weather updates and official advice. If you are advised to evacuate, grab your emergency kit and ID papers and do so immediately. If first responders have set up barricades, do not try to pass them – they have been set up to safely direct people around dangerous areas.

Secure your home

If you have the time and are able to do so safely, unplug appliances and turn off any utilities like electricity, gas and water before evacuating.

Get to high ground

To avoid standing, flowing or rising water, move to higher ground. Never try to walk, swim or drive through fast-moving flood water. If you are in your vehicle and it is filling with water, get onto the roof. If you are trapped in a building, get to the highest level and only go onto the roof if necessary. Do not go into an enclosed space at the highest level of your home, such as a loft or attic, as this could result in being trapped by rising floodwater.

Do not allow children to go into moving or stagnant flood waters

Even if it is a small amount of water in a basement, this can pose risks to your child’s health. Caution teens who are able to drive to never drive during a flood.

Update your loved ones

As soon as you are somewhere safe and communication channels are available, make sure to inform your other family members or those close to you.

Listen for updates

Monitor updates from local authorities and only return home when it is declared safe.

Look after your family’s health

The contaminated water created by flooding poses many health risks to you and your family, such as water-borne illnesses like cholera and typhoid. Keep your children away from floodwater as much as possible – it is likely dirty and contaminated by germs. If your child was exposed to flood waters, make sure to bathe them as soon as you are able and have them wash their hands frequently.  If you or anyone in your family is feeling ill, see a doctor as soon as you are able.

Keep food and water safe

Keep food and water covered to protect from contamination and boil water collected from untreated water sources for at least three minutes before use. Use boiled water to cook and wash food as well as pots, pans and spoons or other things you use for eating. Never drink contaminated water or eat food that has gotten wet.

Clean up safely

Be careful if you pump water from your home. Do it slowly and keep an eye out for hazards such as debris and electrical wires. If you can, dry as much as you can within 24 to 48 hours, keep wet areas well-ventilated and throw away anything that can’t be dried or fixed.  

As much as possible, limit your children’s participation in cleaning up. Before children and teens can safely return, toys, clothing and living spaces should be cleaned and disinfected. Belongings that have been badly contaminated by floodwater should be discarded.

Comforting your children after a flood

Start the conversation and keep it open

  • Make sure you provide your child with opportunities to talk about how the flood made them feel and encourage them to share any worries or feelings of fear or anxiety.
  • Show them that you are listening carefully and care deeply about how they are feeling.

Provide reassurance

  • Let them know that the flood and its aftermath are not permanent and explain to them that they are natural events, and not anyone’s fault.  
  • Give your children reassuring affection by spending time together and providing lots of extra hugs.

Watch for signs of emotional distress

While many children will seem okay for a month or so following a disaster, the numbness can wear off and they can begin showing symptoms of trauma. Some ongoing anxiety is to be expected, but if it does not stop after a few months or if your child is experiencing more extreme symptoms, such as panic attacks or wanting to harm themselves or others, reach out to your family doctor or mental health professional immediately.

Practice calming exercises together

Deep belly breathing is very helpful and is something you can do together with your older children. If you have a younger child, you could make it into a game: Every hour on the hour, see how you can calm your mind and body down by slowing down your breath.

Try to maintain some kind of routine

Though it may be incredibly difficult, going to bed or eating at the same time will help your child to feel a bit more connected to their life before the flood.
