Right now
The most recent data we hold from NOAA arrived 2 hours 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 22 July 2026 at 05:15 UTC. It is kept here as a record.
It is the 16th strongest of the 24 detections recorded within 20 km of this point since 8 May 2026. Another comparable one was recorded here earlier the same day. 4 more were recorded here in the fortnight before it.

How we know
One source: NOAA. Not yet confirmed by a second, independent source.
Our own score for this event is 41 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.

Safety Information
During a tropical cyclone: shelter in a sturdy interior room away from windows. Stock emergency supplies including water, food, medications, and flashlights. Do not venture outdoors during the eye of the storm. After passage, beware of downed power lines, flooding, and structural damage. Follow official guidance for evacuation and shelter.
Series begins 8 March 2026. Comparisons refer to that period only. Collection gap: 14-26 August 2026.
