Blizzard Records Explained: Snow, Wind, Visibility, Duration, and Drifts
What blizzard records measure, why visibility and wind matter, and how snow depth, drifts, and storm duration shape impacts.
Quick answer: Blizzard records are about more than snow totals because wind, visibility, duration, and drifting control the danger.
Definition clues
Blizzard conditions involve strong wind or frequent gusts, falling or blowing snow, and very low visibility for an extended period.
A place can have blizzard conditions without the deepest snow total.
Drifting
Wind can move snow into deep drifts and expose bare pavement nearby.
That makes measurement and travel conditions highly uneven.
Impact records
Power outages, road closures, stranded vehicles, and livestock losses can define historic blizzards.
Duration often drives the severity.
