Right now

The most recent data we hold from NOAA arrived 2 minutes ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.

Nothing else has been detected within 20 km in the last 24 hours.

This alert expired on 4 July 2026 at 23:45 UTC. It is kept here as a record.

No stronger detection stands among the 58 recorded within 20 km of this point since 17 April 2026 — 26 others scored the same. Another comparable one was recorded here earlier the same day. 3 more were recorded here in the fortnight before it.

What the source measured

How we know

6 recorded sources include NOAA; independence is not established by this count.

Our own score for this event is 39 out of 100.

This is our versioned heuristic index, not source severity or a calibrated probability. Urban PEI does not count unique people.

Computed under scoring rules v1. Rows carrying other versions were judged by different rules and are not directly comparable.

Physical priority index · v1. Heuristic priority, not calibrated probability, predictive accuracy or damage. The legacy data-support index combines assigned source support and field availability. Urban PEI is distance-weighted and does not count unique people; zero does not establish that nobody is present. Model cards.
