The most recent data we hold from NOAA arrived 70 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.

How we know
One source: NOAA. Not yet confirmed by a second, independent source.
Our own score for this event is 58 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.
Series begins 8 March 2026. Comparisons refer to that period only. Collection gap: 14-26 August 2026.
This data is aggregated algorithmically from scientific sources. Not a replacement for official emergency warnings.

Safety information
What to do in a tornado
Three things first, then what to do before, during and after. From FEMA’s Ready.gov and the US National Weather Service.
For this reportSevere Weather · United States
Go to the lowest, innermost room
A basement or a storm shelter; otherwise an inner room without windows on the lowest floor. Protect your head and neck.
Ready.govLeave a mobile home
It gives no protection: go to a sturdy building or a shelter before the tornado arrives.
Ready.govOutdoors or in a car
Find the strongest shelter you can. If there is none, lie flat in a low place and cover your head. Never under a bridge.
Ready.gov
Before, during, after. Here it is “after”.
Before · When tornadoes are possible
Get the warnings
Phone alerts and weather radio, day and night.
Choose your safe room
Lowest floor, inner, no windows; everyone at home should know it.
Know the signs
A rotating cloud, a cloud of debris, a loud roar like a train.
Ready.gov (FEMA)
During · When a warning is issued
Go now
To your safe room, without waiting to see it.
Cover up
Arms over head and neck; blankets or a mattress over you.
Ready.gov (FEMA)
After · When it has passed
Keep away from fallen lines
And from damaged buildings.
Clean up protected
Sturdy shoes, gloves, a mask.
Messages, not calls
Keep lines free for emergencies.

Questions people ask
What is the difference between a tornado watch and a warning?
A watch means tornadoes are possible: be ready. A warning means one has been seen or detected on radar: take shelter now. Source: US National Weather Service.
Should I open the windows?
No. It does not help, and it wastes time you need to take shelter. Source: US National Weather Service.
Is an overpass a good shelter?
No. Wind speeds up under it and carries debris. Source: Ready.gov (FEMA).
