How to prepare

Full guide ↗

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.
