US Power Outage Risk Map
Every state loses power for different reasons. Tap a state to see what drives its outages, the storms that caused the worst ones, and how to size backup power for it.
No active Atlantic storms right now — but it is hurricane season. Systems can form and reach Florida in days.

Most weather outages in the US
The most outage-prone state — hurricanes on the coast and a grid that failed statewide in 2021.
Notable outages
What the icons mean
Hurricanes & tropical storms
Gulf and Atlantic landfalls drive the longest multi-day outages in the country.
Winter & ice storms
Ice loading snaps lines and freezes generation; restoration is slow in the cold.
Tornadoes & derechos
Severe convective storms and straight-line winds level distribution grids fast.
Wildfire & public-safety shutoffs
Fires and preemptive PSPS de-energizations cut power for hours to days.
Grid strain & extreme temperature
Heat and cold push demand past supply, triggering rolling blackouts.
Severe storms & flooding
Thunderstorms, high wind and flooding are the steady background outage cause.
Dominant-hazard geography follows NOAA and American Red Cross regional summaries; outage rankings follow Climate Central and EIA reporting; named events are verifiable historical outages. Risk levels are a relative planning indicator, not a statistic.
