Be ready before it hits
Practical steps for the hazards El Niño and La Niña amplify — before, during and after. Summarised from Ready.gov / FEMA, Red Cross / IFRC, CDC, WHO and WMO. Always follow your local authorities first.
EMERGENCY KIT & FAMILY PLAN
Build a kit that can sustain each person for at least 3 days (7 if you can), and agree a family plan before any hazard hits.
- Water — at least 4 litres (1 gallon) per person per day for 3+ days.
- Non-perishable food for 3+ days, plus a manual can opener.
- Medications (7-day supply), first-aid kit, hygiene items.
- Battery/hand-crank radio, torch, spare batteries, power bank.
- Copies of ID, insurance and medical documents in a waterproof bag; some cash.
- Agree a meeting point and an out-of-area contact everyone can call/text.
- Plan for infants, elderly, people with disabilities, and pets.
Flooding
El Niño / La Niña can drive heavy rainfall, river and flash flooding, and landslides.
Before
- Know if you are in a flood-prone or low-lying area; plan a route to higher ground.
- Move valuables and electrics above expected flood level; prepare sandbags if available.
- Charge phones and keep your go-bag ready when heavy rain is forecast.
During
- Turn Around, Don’t Drown — never walk, swim or drive through flood water (15 cm can knock you down, 60 cm floats a car).
- Move to higher ground immediately if told to evacuate; avoid bridges over fast water.
- Stay away from downed power lines; assume water is contaminated.
After
- Return only when authorities say it is safe; watch for weakened structures.
- Do not use wet electrical devices; boil/treat water until declared safe.
- Document damage with photos for aid/insurance.
Tropical cyclone / storm surge
ENSO shifts where cyclones form and track; some regions see more intense storms and surge.
Before
- Know your evacuation zone and route; reinforce/secure roof, windows and loose objects.
- Prepare your kit, fuel and cash before the storm; agree when you will leave.
- Follow the official storm category and warnings — do not wait for the eye to pass.
During
- Shelter in a small, windowless interior room on the lowest safe floor.
- Stay indoors during the calm "eye" — winds return suddenly from the opposite direction.
- Evacuate early if in a surge zone; surge, not wind, causes most deaths.
After
- Beware downed lines, gas leaks, and flood water; do not sightsee.
- Use generators outdoors only — carbon-monoxide kills.
Drought & water scarcity
El Niño can bring prolonged dry spells, crop failure, water and energy stress, and wildfire conditions.
Before
- Store water and prioritise drinking/cooking use; fix leaks.
- Plant drought-tolerant crops; conserve soil moisture (mulching).
- Track official seasonal forecasts and water-restriction notices.
During
- Follow water-rationing rules; reuse greywater for plants where safe.
- Protect livestock with shade and water; reduce herd if advised.
- Watch for heat and wildfire risk that often accompany drought.
After
- Rebuild water stores before the next dry season.
- Assess soil and replant with resilient varieties.
Extreme heat
El Niño years frequently bring record heat, dangerous to health, agriculture and energy.
Before
- Identify cool places (air-conditioned buildings) you can reach.
- Check on elderly, infants, outdoor workers and people with chronic illness.
- Never leave children or pets in parked vehicles.
During
- Drink water regularly even before you feel thirsty; avoid alcohol and heavy meals.
- Stay indoors during peak heat; wear light, loose clothing; limit exertion.
- Know heat-stroke signs (confusion, hot/dry skin, fainting) — call emergency services and cool the person.
After
- Keep hydrating; watch vulnerable people for delayed heat illness.
Wildfire & smoke
Drought and heat raise wildfire risk; smoke (PM2.5) harms health far from the fire.
Before
- Create defensible space — clear dry vegetation around buildings.
- Prepare N95/FFP2 masks and a plan to seal indoor air; ready a go-bag.
- Sign up for local fire alerts and know multiple evacuation routes.
During
- Evacuate early when told — fire moves faster than you expect.
- If trapped by smoke, stay indoors, close windows, run air filtration; wear N95 outdoors.
- Check live air-quality (AQI) before any outdoor activity.
After
- Return only when cleared; watch for hotspots, ash and weakened trees.
- Keep masks on during clean-up; ash can be toxic.
