Prepare for Heavy Rain and Typhoons

Typhoons cause heavy rain over large areas within short periods of time. This can cause rivers to rise and burst their banks, leading to damage and disasters such as inundation and flooding. It is therefore very important to prepare ahead of heavy rain or typhoons.

Advance preparation

  • Do not make non-essential trips.
  • Make sure windows and shutters are locked.
  • Keep gutters and drains clear of debris to ensure smooth drainage.
  • Secure objects that could be blown away.
  • Check your emergency supply kit.
  • Storm-proof your windows (with window film, for instance).
  • Have an emergency supply of water (for drinking, cooking, and hygiene) ready in case water supply is disrupted.
  • Make sure you know where your local evacuation area (hinan basho) is.

Characteristic hazards of torrential rain

  • Dangerous situations can occur in short periods of time.
  • Rain far away can have an effect.
  • Rain not severe enough to generate advisories or warnings may still cause disasters.

Dangers of flooding caused by torrential rain

  • Water pressure can prevent basement doors from opening, or the force of water flowing into a basement can make evacuation difficult. Evacuate basements quickly!
  • When a car becomes submerged and non-functioning, you risk becoming trapped inside the vehicle if the water level reaches about half the height of the door. Avoid driving through underpasses and low-lying areas where there is risk of submersion!
  • Flooded roads can conceal manholes that can suck you in along with the large amounts of rainwater pouring in. Avoid making non-essential trips!
