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.

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.
