Three active wildfires are burning across Oregon right now—Hopkin in Gilliam, Crosswhite and Cove Creek both in Wheeler County. But here's what separates a contained perimeter from a catastrophic spread: wind. A 15 mph gust can accelerate flame travel by 400%. The Brain Dashboard doesn't guess. It fuses five real-time data streams into a live wildfire risk score that updates every hour, letting you see not just where fires are, but where they're going.

THE WILDFIRE RISK FORMULA

Pandita Data's wildfire intelligence engine weighs five signals. Think of them as five spotters in a control room, each watching a different threat horizon:

🛰️
Fire Proximity (40%)
NASA FIRMS satellite detects active thermal signatures in near-real-time. Distance to nearest detected fire is the heaviest weight in the algorithm—closer = exponentially higher risk.
Primary Signal
💨
Wind Speed & Direction (25%)
NOAA wind vectors show how rapidly flames advance. A 20 mph wind can extend fire perimeter 2+ miles daily. Directional data predicts which zones face imminent spread.
Dynamic Multiplier
🌡️
Drought Index (20%)
USDA Palmer Drought Severity Index + soil moisture anomalies reveal how dry vegetation is. Severe drought (PDSI < -3) increases burn probability by 300%.
Fuel Condition

Rounding out the model: vegetation density (NDVI, 10%) shows fuel load, and terrain slope (5%) accounts for how uphill flame travel accelerates. Steep slopes can double fire speed.

HOW WIND TURNS DISTANCE INTO DANGER

Wind is the wildcard. At 0 mph, a fire spreads at roughly 10 feet per hour upslope. At 20 mph, that jumps to 200+ feet per hour. The Brain Dashboard applies directional wind vectors in real-time, meaning a shift from easterly to westerly can completely redraw a zone's risk profile in minutes.

THE NDVI VEGETATION FUEL GAUGE

NDVI (Normalized Difference Vegetation Index) is NASA's way of measuring plant greenness—essentially, how much burnable fuel is standing in a zone. Healthy, green vegetation = low NDVI = harder to ignite. Dead, desiccated brush = high NDVI anomaly = tinder box. Oregon's current drought is pushing NDVI into critical zones across Wheeler and Gilliam counties, making the Crosswhite, Cove Creek, and Hopkin fires particularly volatile.

LIVE MONITORING

The Brain Dashboard integrates all five signals into a single risk score (0–100), updated hourly. Zone your location, see real-time wildfire proximity, check wind-driven spread vectors, and download Disaster Reports for your city. Currently tracking 10 active wildfires across western US. Wheeler County residents should monitor wind shifts daily.

Wildfire risk isn't mystery. It's physics, satellite data, and meteorology converging into one transparent, live score. Check the Brain Dashboard now.
