Right now
The most recent data we hold from NOAA arrived 51 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 22 June 2026 at 01:50 UTC. It is kept here as a record.
No stronger detection stands among the 115 recorded within 20 km of this point since 11 March 2026 — 19 others scored the same. Another comparable one was recorded here earlier the same day. 13 more were recorded here in the fortnight before it.

Safety Information
If a tornado warning is issued: go to a basement or an interior room on the lowest floor, away from windows. A vehicle and a mobile home are not shelter. Cover your head and neck. Wait for the official all-clear before going outside, and watch for downed power lines and gas leaks afterwards.
Series begins 8 March 2026. Comparisons refer to that period only. Collection gap: 14-26 August 2026.
