Spring Tornado Season 2026 Mapped: How Long Since Each U.S. Region Last Saw a Tornado Warning
UNITED STATES — As severe weather activity enters a quieter stretch, a new map valid as of May 28, 2026 reveals exactly how long it has been since each NWS forecast office last issued a tornado warning across the country. The data paints a clear picture of where the 2026 spring tornado season has been most active and where silence has reigned for years.
What This Map Measures
The map tracks days since the last NWS Tornado Warning for each forecast area. A tornado warning does not confirm a tornado touched down — only that one was issued by forecasters. The color scale runs from 0 days (gray/white) to over 3,800 days (deep red), with darker reds indicating regions that have gone years without a single warning.
The Active Zone: Central and Southern Plains Plus the South
The blue and light blue zones across the map mark areas that have seen tornado warnings within the last 1 to 31 days, and they dominate the central and southern United States. Notable values include:
- 0 days in parts of Texas, Oklahoma, Louisiana and Mississippi, meaning warnings were issued as recently as today
- 1 to 9 days across much of Kansas, Missouri, Arkansas, Tennessee, Alabama, Georgia and the Carolinas
- 28 days across several zones in Indiana, Illinois and Kentucky
This corridor confirms the central and southern Plains plus the mid-South have carried the bulk of 2026 spring tornado warning activity.
The Silent Zone: West and Pacific Northwest
The most striking feature of the map is the deep red and brown zone blanketing the western United States, where tornado warnings are extraordinarily rare. Standout values include:
| Region | Days Since Last Warning |
|---|---|
| Parts of Oregon/Washington | 5,710 and 6,887 days |
| Northern California coast | 3,309 days |
| Nevada/Utah interior | 2,110 to 2,556 days |
| Colorado Rockies zone | 5,366 days |
| Parts of Wyoming/Montana | 2,370 to 2,422 days |
These numbers reflect over a decade without a tornado warning in some of the most isolated western forecast zones.
The High Plains Reset Coming in June
Forecasters note that the High Plains region is expected to see these day-counts reset later in June, as the severe weather pattern shifts and tornado-producing storms return to eastern Colorado, Nebraska and Kansas. Several High Plains offices currently sit in the 273 to 365 day range, meaning they have gone roughly a year without a warning.
The Northeast and Great Lakes
Much of the Great Lakes and Northeast sits in the 39 to 142 day range, reflecting modest spring activity. A few isolated offices in New England show values of 313, 436 and 685 days, indicating limited but occasional tornado warning activity in recent years.
Spring 2026 in Context
With severe weather now easing across the core tornado belt, the 2026 spring season is moving into a transitional phase. The zero-day zones in Texas and the Gulf states confirm activity was ongoing right through late May, while the broader blue sweep across the mid-South reflects a consistently active season across traditional tornado alley and Dixie alley alike.
