How to prepare

Full guide ↗

Mixed / variable hazards

This region can swing between flooding and drought depending on the phase and season.

Before

  • Prepare for both wet and dry extremes; keep a general emergency kit ready.
  • Follow your national meteorological agency for the current seasonal outlook.

During

  • Act on the specific official warning issued for your area.

After

  • Restock supplies and review your plan after each event.

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.

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.
