Understanding flood events

River, flash, urban and coastal flooding events. Flood damage depends less on total rainfall than on how fast water arrives and where it has to go. Flash floods in urban areas can rise within minutes because sealed surfaces stop absorption, while river floods build over days and allow more warning time.

How severity is rated

Global Incident Tracker rates every event on a four-step scale — Minor, Moderate, Severe and Extreme — derived from the source signal: earthquake magnitude, official GDACS alert colour, or the volume of independent media reporting for news-derived incidents. This event is currently rated Severe. Ratings can change as more information becomes available, and a rating is a monitoring signal rather than an official government assessment.

Safety guidance for flood situations

  • Never walk or drive through floodwater — 15 cm of moving water can knock you down and 60 cm can float a car.
  • Move to higher floors or higher ground early; do not wait for water to reach you.
  • Switch off electricity at the mains if water is entering the building and it is safe to reach.
  • Treat all floodwater as contaminated: wash hands, boil drinking water and clean wounds.
  • Follow only official instructions from local authorities and emergency services — this page is a monitoring record, not an emergency alert.
