Household Disaster and Flood Preparedness in Malaysia

River water rising to road level at two in the morning is not the time to start hunting for birth certificates and filling water bottles — that is the time to get out. In Malaysia, the disaster most likely to force your family from home is not a great earthquake or a typhoon, but the monsoon flood that comes almost every year. This guide sets out what you need to do before, during and after a flood, along with other risks such as landslides, haze and Sabah earthquakes, so that the important decisions are made long before the water reaches your door.

When is Malaysia’s flood season most at risk?

The most frequent and most widespread disaster hazard in Malaysia is flooding, and its cause is predictable: the Northeast Monsoon (NEM). This season usually begins in mid-November and lasts until March, bringing continuous heavy rain that often overflows rivers on the Peninsula’s east coast — Kelantan, Terengganu, Pahang and eastern Johor — as well as Sarawak and Sabah.

For the 2025/2026 season, MetMalaysia forecasts the monsoon beginning on 13 November 2025 with five to seven episodes of continuous heavy rain throughout the period. Each episode can last several days, and it is that prolonged rain — not a brief downpour — that usually triggers major flooding in low-lying areas and along riverbanks.

In preparation for the 2024/2025 monsoon, the Department of Irrigation and Drainage (JPS) identified 4,619 flood hotspots nationwide. Other reported readiness measures included 543 flood-warning sirens and 737 mobile pumps stationed across the country, with continuous monitoring by the National Flood Forecasting and Warning Centre (PRABN) supported by MetMalaysia and state governments. (These figures are drawn from an October 2024 statement and should be reviewed each season.)

The most important thing for you: if you live near a river, in a low-lying area, or in one of the flood hotspots, treat every monsoon season as a possible evacuation — not a distant possibility.

What do the Waspada, Buruk and Bahaya rain warnings mean?

Floods rarely come without warning. MetMalaysia issues continuous-rain warnings based on the amount of rain expected within a 24-hour period, and understanding these levels lets you act before conditions become dangerous.

Warning level	Rain threshold (24 hours)	Meaning and action
Waspada	Less than 150 mm	Continuous rain expected; risk of flooding in low-lying areas. Monitor weather news and prepare your emergency kit.
Buruk	Over 150 mm	Potential flooding in low-lying and riverside areas; crops may be damaged. Move belongings to higher ground, fill your vehicle with fuel.
Bahaya	Over 250 mm	Risk of major flooding and landslides on hill slopes; weak structures, roads and bridges may be damaged. Be ready to evacuate immediately when instructed.

The 24-hour period is counted from when the rain starts falling. Warnings can change quickly, so do not rely on a single alert. Check the latest status through MetMalaysia’s myCuaca website and app, or call the 1-300-22-1638 line. For real-time river water levels, refer to the InfoBanjir portal (publicinfobanjir.water.gov.my) operated by JPS.

What should be in an emergency kit?

An emergency kit — sometimes called a “72-hour bag” — is designed to cover your family’s needs for at least three days before help arrives. Prepare it in advance, not on the night the water rises. Keep it somewhere easy to reach near the door, in a waterproof bag.

A basic list for every household:

• Water and food for at least 3 days — bottled water, canned food, dry biscuits and energy bars that need no cooking.
• Light and power — a solar lamp or torch, spare batteries, and a power bank for your phone.
• First-aid kit — bandages, antiseptic, plasters, small scissors, gloves, and personal medication (fever, pain, asthma, blood-pressure or diabetes medicine if any family member needs it).
• Whistle — to attract attention if you are trapped.
• Important documents — copies of identity cards, passports, birth certificates, land titles and insurance policies in a waterproof container. Also keep digital copies on your phone or in the cloud.
• Cash — ATMs and electronic payments may not work when the power is cut.
• Special needs — diapers, wet wipes and formula milk for babies (enough for 3 days); needs of the elderly or persons with disabilities; pet food.
• Clothing and warmth — dry spare clothes, towels, and light blankets.

Update this kit every year before the monsoon — check the expiry dates of medicines and food, and replace the batteries.

What to do BEFORE a flood?

Real preparedness happens while the weather is still fine. Several decisions that are hard to make in a panic become easy when planned in advance.

1. Identify the PPS nearest to you. For the 2024/2025 season, the Department of Social Welfare (JKM) stated its readiness to activate 8,481 Temporary Relief Centres with a capacity of about 2,158,743 victims nationwide. Know which one is closest, and a route to it that does not pass through easily-flooded areas.
2. Plan a route and a family meeting point. If family members are separated, set a place to meet and a number to call.
3. Save emergency numbers on your phone and write them on paper — 999, the fire station, the district council and your state’s Disaster Operations Control Centre.
4. Move valuables to higher ground — documents, electrical appliances, and sentimental items to an upper floor or high shelves.
5. Ready your vehicle and supplies — fill the fuel tank, and make sure your power bank and lamp work.
6. Understand the evacuation signals — when the authorities order an evacuation, do not wait for water to enter the house first.

What to do DURING a flood and evacuation?

When the water starts to rise or an evacuation order is issued, saving lives takes precedence over all property.

• Switch off the electricity and gas in the house before leaving to avoid shocks and fires.
• Do not walk or drive through fast-moving water. Knee-deep moving water can knock down an adult, and water at car height can sweep a vehicle away. You cannot see holes, open drains or cables beneath murky water.
• Take only your emergency kit and important documents; do not delay carrying furniture.
• Follow the authorities’ instructions and go to the designated PPS. When checking in, make sure the head of household and all family members are recorded — this registration is important for aid later.
• Avoid hill-slope areas during heavy rain because the risk of landslides increases.
• Do not return home to fetch belongings until the area is declared safe.

For those who are not evacuated but are trapped, go to the highest safe place, avoid unstable roofs, and use a whistle or light to attract the attention of rescue teams. Call 999 for immediate help.

What to do AFTER a flood?

The danger does not end when the water recedes. The post-flood phase brings its own health and safety risks.

• Wait for confirmation that it is safe before returning. Building structures, roads and bridges may be weakened.
• Be careful with electricity — do not switch the supply on until the wiring is inspected; submerged appliances may be dangerous.
• Maintain hygiene and health — flood water is often contaminated. Clean and disinfect surfaces, throw away submerged food, and boil drinking water if the supply is in doubt. Watch out for waterborne diseases such as leptospirosis (rat urine disease) and diarrhoea.
• Take photos of the damage for insurance claims and aid before cleaning up.
• Register for aid — make sure your household is recorded at the PPS or with the local authorities in order to apply for Bantuan Wang Ihsan and other assistance.

How to apply for Bantuan Wang Ihsan and other aid?

After a flood, the government channels Bantuan Wang Ihsan (BWI) to victims. This aid is given to the head of household affected by disasters such as floods, landslides, fires and storms.

Feature	Details
Amount per claim	RM1,000
Frequency	Once every three months
Maximum per year	Four times (RM4,000)
Recipient	Affected head of household
How to apply	MyIBJKM app (scan the QR code at the PPS); Victim Registration Centre for those who cannot reach a PPS
Payment method	EFT transfer to a bank account or a cash claim at a Bank Simpanan Nasional (BSN) counter

A few important things to understand:

• If you are affected by disaster twice within a three-month period, only one claim is allowed for that period. A new claim becomes eligible once the three-month period has passed.
• Registration is usually done through the MyIBJKM app by scanning a QR code while the victim is at the PPS, so making sure your name is recorded when you evacuate is the important first step.
• According to NADMA, for the 2025/2026 Northeast Monsoon a total of RM78.342 million was paid to 78,342 heads of household as of 21 January 2026, with more than 98% of applications processed within an average of less than 14 working days for the early episodes. (This figure reflects the situation at the time of reporting and will grow over the season.)

Besides BWI, victims may be eligible for other aid from JKM, state governments, district councils and non-governmental organisations — including food supplies, basic necessities and clean-up assistance. Keep receipts, photos of the damage and PPS registration records to support any claim.

What about landslides, haze and earthquakes?

Floods dominate Malaysia’s disaster risk, but three other hazards belong in your family’s plan.

Landslides. The prolonged heavy rain that triggers floods also increases the risk of landslides on hill slopes and highland areas. MetMalaysia’s Bahaya warning specifically mentions the landslide risk. If you live or drive in hilly areas during heavy rain, watch for signs such as ground cracks, murky water from slopes, or unusual noises, and avoid stopping beneath steep slopes.

Haze. Unlike floods, haze usually occurs in the dry season (sometimes June to October) as a result of open burning and regional forest fires. Monitor the Air Pollutant Index (API) readings, which can be accessed through the NADMA Disaster Portal. When the API is high, limit outdoor activity, close windows, use an air purifier if available, and wear a suitable face mask — especially for children, the elderly and respiratory patients.

Earthquakes. The risk of a major earthquake in Peninsular Malaysia is low, but Sabah lies near a seismically active zone. The Ranau earthquake on 5 June 2015, magnitude 6.0, claimed 18 lives — all of them climbers and tour guides on Mount Kinabalu — and triggered landslides and rockfalls. On 23 February 2026, a magnitude 6.8 offshore earthquake occurred about 49 km west of Kudat at a depth of 678 km; because it was so deep, only mild tremors were felt and there was no tsunami threat. If you are in Sabah and an earthquake occurs, practise “Drop, Cover, Hold On” — get down, shelter your head under a sturdy table, and hold on until the shaking stops.

Emergency numbers and official resources

Save these numbers on your phone and in a written copy before the monsoon season. Emergency lines should be used responsibly and only when truly needed.

Need	Contact
Immediate emergency (fire, rescue, ambulance, police)	999
Weather information and warnings	MetMalaysia — website, myCuaca app, 1-300-22-1638
River water levels and flood info	JPS InfoBanjir portal (publicinfobanjir.water.gov.my)
Disaster coordination / NADMA operations room	03-8064 2400 · opsroom@nadma.gov.my
Disaster and PPS info	NADMA Disaster Portal (portalbencana.nadma.gov.my)

State-level Disaster Operations Control Centres (PKOB) also operate during disasters to coordinate information, victim evacuation and aid in affected areas.

What are the common mistakes to avoid?

• Waiting too long to evacuate. Many victims are trapped because they wait for water to enter the house before acting. When an evacuation order is issued, comply immediately.
• Driving through flood water. Water that looks shallow can be deep and fast; this is the most avoidable cause of flood deaths.
• Preparing the emergency kit at the last minute. Shops run out of stock and the power is cut. Prepare early.
• Not registering at the PPS. Without a registration record, claiming Bantuan Wang Ihsan and other aid becomes harder.
• Keeping important documents in only one place. Keep waterproof copies and digital copies.
• Switching electricity on too soon after a flood before the wiring is inspected.
• Underestimating the health risks of flood water — leptospirosis and waterborne diseases are real.

Decision framework: should I evacuate now?

Use these brief guidelines during continuous heavy rain:

1. Have the authorities ordered an evacuation? If yes — evacuate now. Do not wait.
2. Has a Bahaya warning been issued for your area? If yes — get fully ready, load your vehicle, and be prepared to move when the water starts to rise.
3. Is water already entering your yard or is the road level rising quickly? If yes — evacuate even without an official order; conditions can worsen before help arrives.
4. Do you live in a flood hotspot or near a river? If yes — lower your decision threshold; act earlier than neighbours on higher ground.
5. Do you have high-risk family members (babies, the elderly, patients, persons with disabilities)? If yes — evacuate earlier because they take longer to move.

When in doubt, evacuate early. Homes and property can be repaired or replaced; lives cannot.

Next steps

Make disaster preparedness part of your household’s annual routine, not a panic response. Before the next monsoon:

• Prepare or update a 72-hour emergency kit and check expiry dates.
• Identify the nearest PPS and a safe route to it.
• Save emergency numbers and download the myCuaca app and monitor the InfoBanjir portal.
• Discuss an evacuation plan and meeting point with all family members.
• Review your home and contents insurance coverage against floods.
• If in Sabah, add “Drop, Cover, Hold On” earthquake drills to your family plan.

Review the latest weather warnings on MetMalaysia’s official site whenever a heavy-rain episode is expected, and never rely on a single source of alerts.
