Understanding cold wave events
Extreme low temperatures causing deaths, crop loss and infrastructure failure. Cold waves cause deaths through hypothermia, carbon monoxide poisoning from improvised heating, and cardiac events during exertion such as snow clearance. Infrastructure failures often compound the risk.
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 Minor. Ratings can change as more information becomes available, and a rating is a monitoring signal rather than an official government assessment.
Safety guidance for cold wave situations
- Never use charcoal, generators or gas stoves for indoor heating; carbon monoxide kills silently.
- Dress in layers and keep extremities covered; wind chill accelerates frostbite.
- Check on isolated and elderly people, and keep pipes protected against freezing.
- Avoid heavy exertion such as snow clearance if you have heart conditions.
- 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 GNEWS 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 We deliberately do not publish casualty numbers unless an official source states them.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.
