Where would today's winds carry fallout near Amarillo, Texas?
The map below estimates where today's forecast upper-air winds would carry fallout from each potential target near Amarillo, and whether any of it could reach the city.
Amarillo is itself on this site's list of potential targets (Pantex plant / Amarillo). Close to an explosion, blast and heat are the main dangers, and fallout would begin within minutes whatever the wind.
There are 6 other listed targets in range of Amarillo. The nearest is Dyess AFB, about 224 miles to the south-southeast. F.E. Warren missile field is within 600 miles; a missile field would take many ground bursts, and its fallout can travel much further than that of a single explosion.
Winds high above the continental United States blow from the west more often than not, so targets to the west of Amarillo are upwind most often: Kirtland AFB / Albuquerque. On any given day the pattern can be quite different, which is what the map below shows.
Listed targets in range of Amarillo (illustrative, not a prediction)
| Potential target | Type | From Amarillo |
|---|---|---|
| Pantex plant / Amarillo, TX | Military site | Here |
| Dyess AFB, TX | Military site | 224 mi south-southeast |
| Tinker AFB / Oklahoma City, OK | Military site | 251 mi east |
| Kirtland AFB / Albuquerque, NM | Military site | 267 mi west |
| Cheyenne Mountain / Colorado Springs, CO | Military site | 295 mi north-northwest |
| Dallas, TX | Metro area | 334 mi east-southeast |
| F.E. Warren missile field, WY | Missile field, many ground bursts | 435 mi north-northwest |
Many factors affect where fallout travels and how dangerous it is. This educational tool takes only three into account: the forecast winds from the ground up to the top of the mushroom cloud, an assumed weapon size, and an assumed burst type (on the ground or in the air). The target list is illustrative, not a prediction. How to read the map.

What this map takes into account. Many factors affect where fallout travels and how dangerous it is. This educational tool takes only three into account: the forecast winds from the ground up to the top of the mushroom cloud, an assumed weapon size, and an assumed burst type (on the ground or in the air).
It takes into account:
- Forecast winds at every altitude: speed and direction from the ground to the top of the mushroom cloud, at each target and at points around you, hour by hour for up to 12 hours of travel.
- Assumed weapon size: the size you select, which sets how high the cloud rises and how far this model draws the path.
- Assumed burst type: ground bursts for military sites, and your choice of ground or air for cities. A ground burst produces heavy local fallout; an air burst produces little.
It does not take into account:
- The weapons actually used: their real size, design, number and height of burst, none of which can be known in advance.
- Radiation dose: how strong the radiation would be at any place or time.
- Rain and snow: precipitation is flagged, but the hotspots it creates are not mapped.
- Terrain and local weather: hills, valleys, storms and small-scale winds between forecast points.
- Particle sizes: heavier particles fall sooner and nearer than light ones, which makes real patterns uneven.
- Forecast error: the result is only as good as the weather forecast behind it.
- What would actually be targeted: the target list is illustrative, not a prediction.
Treat the paths as a rough guide to what is likely, not a prediction. How it works.

Official preparedness guidance
This is a summary of public guidance from Ready.gov and the CDC. It does not come from this map, and the map should not be used to make emergency decisions.
- Get inside. Official guidance is to get into the nearest solid building, as deep and central as possible: a basement, or the middle of a large building.
- Stay inside. Official guidance is to stay sheltered for at least 24 hours unless authorities say otherwise, because fallout radiation is strongest in the first hours and decays quickly.
- Stay tuned. Follow official instructions, for example by battery-powered or hand-crank radio.
