See today's fire-weather danger where you are. The Fosberg index turns local temperature, humidity and wind into one clear fire-risk rating. Know the fire risk where you are. Fire Danger Index reads your local weather — temperature, humidity and wind — and turns it into a single, color-coded fire-weather rating you can understand at a glance, so you can plan your day around it. The home screen centers on a clear danger gauge that shifts from green "low" to deep red "extreme," with a one-line summary of what the air and wind mean for fire today. WHAT YOU GET • Daily fire-danger rating — the Fosberg Fire Weather Index for your exact location, shown as an easy number and category. • See what drives it — current temperature, relative humidity and wind speed, the three ingredients behind today's rating. • Plain-language guidance — a short read on whether conditions favor easy ignition and fast fire spread right now. • Why it changes — drier air and stronger wind push the index up; humid, calm weather brings it down. • Quick outlook — get a feel for how the risk is trending so you can plan ahead. WHO IT'S FOR Anyone who lives in or travels through wildfire country, campers and hikers deciding whether to light a fire, farmers and ranchers burning brush, landscapers and outdoor crews, and anyone who simply wants to know how dangerous the fire weather is today. HOW IT WORKS Weather data comes from an open weather model for your location. Enable location for live local readings, or browse sample data offline. The Fosberg Fire Weather Index is computed on your device from temperature, humidity and wind. A NOTE ON ACCURACY This app is for general awareness only. The rating is a modeled estimate from weather data, not an official fire warning, burn permit or evacuation notice. Always follow your local fire authority, posted burn bans and emergency services.
