Understanding cyclone / hurricane events
Tropical cyclones, hurricanes and typhoons with damaging wind and surge. Tropical cyclones cause harm through four separate mechanisms: sustained wind, storm surge, inland flooding from rainfall, and tornadoes embedded in outer bands. Historically, storm surge and inland flooding kill far more people than wind.
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 Moderate. Ratings can change as more information becomes available, and a rating is a monitoring signal rather than an official government assessment.
Safety guidance for cyclone / hurricane situations
- Know whether you are in a storm-surge evacuation zone and leave before roads become impassable.
- Shelter in an interior room away from windows; the eye passing overhead is not the end of the storm.
- Stock water, medication, cash, power banks and documents in a waterproof bag.
- Most cyclone deaths come from water, not wind — take flood warnings as seriously as wind warnings.
- Follow only official instructions from local authorities and emergency services — this page is a monitoring record, not an emergency alert.
Data and verification
This record was generated automatically from the United Nations' Global Disaster Alert and Coordination System (GDACS) and de-duplicated against our archive. Early reports for any incident can be revised: locations get refined, magnitudes are recalculated and impact figures change as assessments arrive. We deliberately do not publish casualty numbers unless an official source states them. The original source report is linked at the top of this page.
