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. We deliberately do not publish casualty numbers unless an official source states them.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.
