Blackout vs. Whiteout: What's the Difference?

Edited by Harlon Moss || By Janet White || Published on December 24, 2023
A blackout is a complete loss of power or consciousness, while a whiteout is a weather condition with reduced visibility due to snow or fog.

Key Differences

Blackouts involve a total cessation of power, plunging areas into darkness. Whiteouts occur in snowy regions, creating disorienting, uniform whiteness that impedes visibility.
A blackout can also refer to loss of consciousness or memory. In contrast, a whiteout specifically relates to weather conditions, not human experiences.
Blackouts can be caused by power grid failures or medical conditions. Whiteouts are typically caused by heavy snowfall or blowing snow.
The term blackout is used metaphorically in various contexts, such as information blackouts. Whiteout, however, is primarily used in meteorological contexts.
Blackouts can have widespread societal impacts, affecting infrastructure and safety. Whiteouts primarily pose risks to travelers and outdoor activities.
