How outage maps are structured
Most outage maps aggregate reports from smart meters, calls, and utility operations systems. A marker may represent many customers, a device, or a service area rather than a precise failed pole.
The most useful fields are update time, customers affected, trend direction, and whether a restoration estimate is preliminary or revised.

FAQ
Why might my power be out before a map updates?
Utilities need reports, telemetry, and validation before map data changes. Field conditions can move faster than public maps.
Can HazardNow tell when my power will return?
No. Restoration estimates should come from your utility or local officials.
