01 · Ignition

Fire puts smoke into the air.

Burning vegetation releases fine particles — small enough to travel, and small enough to reach your lungs.

02 · Lift

Heat carries it upward.

The plume rises past the ridgeline and joins the same winds that steer weather systems.

03 · Transport

Wind moves it across states.

Smoke can travel a thousand miles from a fire that never moves an inch.

04 · Forecast

Which makes it predictable.

NOAA models the plume hour by hour. Smaze reads that forecast for one place and says what it means.

See the smoke before it arrives

And know when it clears. Where the fires are. Which way the wind is pushing. One map of US wildfire smoke, from NOAA, every hour.

Prineville, OR has the worst forecast air quality in this run — a peak of AQI 273 (Very Unhealthy).

Full forecast

Every location

Worst air first.

When smoke is moving, the question is who is getting hit. Every place we forecast, ranked by how bad it gets in the next day. The number is the US air quality scale — under 50 is clean, over 100 is worth taking seriously.

Prototype run. This build is generated from the captured fixture, whose tiles hold only forecast hours 1, 12, 13 rather than every hour. A production run publishes dense tiles and this page renders 24 columns.

What you are looking at

Plain answers, from public data.

Wildfire smoke is forecast the same way rain is. Here is where the numbers come from and what they mean.

Who measures it

NOAA, the US weather service.

The same government agency that forecasts hurricanes runs a smoke model for the whole country. It updates every hour and it is free and public. Smaze reads it and does nothing to it except make it readable.

This map: NOAA NDGD for smoke, NOAA HRRR for wind. Fire locations come from NIFC and are an app feature.

What it shows

Two different things.

Air quality is the smoke down where you breathe. That is the number that matters for going outside.

Sky smoke is all the smoke above you, all the way up. That is why the sun can look orange on a day the air is fine.

Surface PM2.5 in micrograms per cubic metre, and total column smoke in milligrams per square metre.

How to read it

Brighter means more smoke.

On the map, dark is clear air and bright orange is heavy smoke. The blue lines are the wind, showing which way it is pushing.

For air quality we use the US AQI — the same 0-500 scale on every weather app. Under 50 is fine. Over 100, sensitive people should take it easy. Over 150 affects everyone.

This is a forecast, not a measurement — the same as a rain forecast. It can be wrong. For official air quality readings and health advice, see AirNow.
