How we know
One source: Korea Meteorological Administration (KMA). Not yet confirmed by a second, independent source.
Our own score for this event is 46 out of 100.
This is our versioned heuristic index, not source severity or a calibrated probability. Urban PEI does not count unique people.
Computed under scoring rules v5. Rows carrying other versions were judged by different rules and are not directly comparable.
Series begins 8 March 2026. Comparisons refer to that period only. Collection gap: 14-26 August 2026.
This data is aggregated algorithmically from scientific sources. Not a replacement for official emergency warnings.

Safety information
What to do in a winter storm or extreme cold
Three things first, then what to do before, during and after. From FEMA’s Ready.gov and the US National Weather Service.
For this reportSevere Weather · Jenzan
Stay off the roads
Travel only if you must. If you are stuck in a car, stay in it, run the engine a few minutes an hour with the exhaust clear of snow.
Ready.govHeat safely
Never heat the house with an oven, a barbecue or a generator indoors: carbon monoxide kills without warning.
Ready.govWatch for frostbite and hypothermia
Numb, white or greyish skin; shivering, confusion, slurred speech. Get warm and get help.
Ready.gov
Before, during, after. Here it is “after”.
Before · When a storm or a cold wave is forecast
Supplies for several days
Water, food, medicines, torches, batteries.
A kit in the car
Blankets, water, snacks, jump leads; keep the tank full.
Carbon monoxide alarm
Install and test one, with the smoke alarms.
Ready.gov (FEMA)
During · In the storm or the cold
Layers
Several warm layers, hat and gloves; limit time outside.
Shovel slowly
Hard effort in the cold strains the heart.
Generators outdoors
At least six metres from windows and doors.
Ready.gov (FEMA)
After · When it passes
Warm frostbite gently
With body heat or warm (not hot) water; do not rub.
Warm hypothermia from the core
Chest, neck, head and groin first, in dry blankets.
Check on others
Older people, children and pets.
Ready.gov (FEMA)
Questions people ask
How do I recognise hypothermia?
Shivering, exhaustion, confusion, fumbling hands, memory loss, slurred speech, drowsiness. Get the person warm and call for help. Source: Ready.gov (FEMA).
Can I use a gas oven to heat the house?
No. Ovens, barbecues and generators indoors produce carbon monoxide, which kills without warning. Source: Ready.gov (FEMA).
Should I stay in a car stuck in snow?
Yes: it is shelter, and people are found more easily with their car. Keep the exhaust pipe clear of snow. Source: Ready.gov (FEMA).
