Warned counties in the latest file, 6 Sep 2026 to 10 Oct 2026164 county-event rows, 17 states
This is a weekly county-level file of National Weather Service Severe Thunderstorm, Tornado, Flash Flood and High Wind warnings. It is not an address list, not a hail map, and it does not predict damage. We take one reading of the National Weather Service warnings feed a week, and each reading is the warnings in force at that moment. This file groups our latest 6 readings, dated 6 Sep 2026 to 10 Oct 2026, by county and event. A warning that began and ended between two readings is not in it, so it is not every warning of the week. The first 12 rows are printed here; the sample file below carries 25 of them; the paid file carries all of them. No street. No person's name.

A warning is not a damage report. The National Weather Service issued a warning for that county. Whether a roof was hit, we did not see and will not imply.
Hail and wind figures are parsed from the warning text when they are present, and left blank when they are not. 138 of 164 rows in this file have no hail size in our copy.

Who published the data on this page
The National Weather Service, an office of the National Oceanic and Atmospheric Administration, publishes the warnings. We read the public alerts feed at api.weather.gov, seal a dated copy once a week, and group the copies we hold by county and event. NWS material is in the public domain and is not subject to copyright protection. This file is our grouping of those records. It is not an official National Weather Service product, and it does not imply an endorsement.
Source named: National Weather Service active alerts, api.weather.gov/alerts/active. Disclaimer: weather.gov/disclaimer. We do not use the NWS name or mark as a logo.
What you get
- One US file a weekEvery county that had a Severe Thunderstorm, Tornado, Flash Flood or High Wind warning in force at one of our weekly readings (up to the last seven), grouped by county and event. The window each file covers is stated at the top of this page.
- County, event, hail, wind, times, officeweek ending, state, county FIPS, county name, NWS zone, event, warning count, max hail inches where the text carried a number, max wind mph where the text carried a number, first onset (UTC), last expiry (UTC), issuing office. No street, no person's name, no phone.
- Named reading datesThe page names the date of every reading the file groups. A warning that began and ended between two readings is not in it.
- An honest empty weekIf no reading the file groups has a matching warning, the file is the column headings and no rows.
We hold 83 county-alert rows in the 10 Oct 2026 reading. That is the matching warnings active on that day, not an archive. The paid file is the county grouping described above.

You do not have to take our word for what is in the file. Here are 25 rows of the real thing, carrying all 12 of its columns, cut out of the dated weekly file we sealed ourselves. Nothing in it is made up and nothing in it is tidied up.
- Open the 25 rows as a CSVA plain spreadsheet file. It saves to your machine rather than painting itself into a browser tab, and it opens in Excel, Numbers or Google Sheets.
- The same 25 rows as JSONThe same rows again, laid out for reading with code.

These 25 rows are a slice of the file, not the whole of it. What we cannot show you here is how far back it goes: no further than the readings named above (6 Sep 2026 to 10 Oct 2026). The paid file is the county grouping of those readings, not a longer history.
