A detection is a hot spot seen from space. It can be a wildfire, a planned burn or an industrial site. It does not show a fire’s name, size or containment.

What is a Red Flag Warning?
The National Weather Service issues a Red Flag Warning when strong wind, low humidity and dry plants come together. Any spark — from a campfire, a cigarette or a dragging trailer chain — can start a fire that spreads very fast. A Fire Weather Watch means these conditions are possible in the next 12 to 72 hours.
If a wildfire is near you: Ready, Set, Go
For smoke: stay indoors with windows closed, run an air purifier if you have one, and check the air quality before going outside.
Wildfire questions
What is a satellite fire detection?
NASA satellites pass over North America several times a day and flag spots that are much hotter than their surroundings. Most are fires, but some are planned burns, gas flares or factories. A new detection can appear within a few hours.
How far can wildfire smoke travel?
Hundreds or even thousands of miles. That is why the air quality can drop even when no fire is close.
Where can I find evacuation orders?
Evacuation orders come from your county or local emergency office. Follow them first, and use this map to see where fires are.
