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.
