Largest first. "Out since" comes from the utility when it says, otherwise it's when this board first saw the outage (marked with ≥). Restore times are the utility's estimate.
Planned shutoffs utilities use in high fire danger, from PG&E's and SCE's shutoff maps. Shutoffs already in progress also show as outages with the cause "Public safety shutoff".
GridVigil's pressure score (0 to 100). High pressure in a heat wave means Flex Alerts and, at worst, rotating outages.
Strong gusts with dry air are what trigger safety shutoffs. Red marks gusts of 25 mph or more with humidity at or under 25%, or 15 mph or more at or under 15%.
US AQI modeled by Open-Meteo (CAMS) at each county's center. Wildfire smoke can be much worse locally; check AirNow's fire and smoke map for sensor readings.
Active fires from Cal Fire (California) and NIFC (Oregon), satellite heat detections from kanari.io (last 48 hours, probable or corroborated), and USGS earthquakes M2.5+ in the last day.
IODA active probing: address blocks that answered, as a share of each network's 24 hour median. A drop of a few points across a whole carrier is a real outage. These are statewide, so a single neighborhood outage won't show.
From official status pages, OutageDeck and LiveOrDown (independent probes from 3 regions). Problems first within each group.
