Understanding storm events
Severe thunderstorms, windstorms, hail and winter storms. Severe storms combine wind, lightning, hail and sudden downpours. Secondary effects — falling trees, power line damage and flash flooding on roads — cause the majority of injuries.
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 storm situations
- Move indoors and away from windows; avoid sheltering under trees.
- Unplug sensitive electronics and avoid using wired equipment during lightning.
- Assume every downed power line is live and keep well clear.
- Do not drive through flooded underpasses.
- Follow only official instructions from local authorities and emergency services — this page is a monitoring record, not an emergency alert.

Early reports for any incident can be revised: locations get refined, magnitudes are recalculated and impact figures change as assessments arrive.
