This alert expired on 1 July 2026 at 05:33 UTC. It is kept here as a record.

No stronger detection stands among the 34 recorded within 20 km of this point since 27 April 2026 — 4 others scored the same. Another comparable one was recorded here earlier the same day. 5 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.
