Central Hazards Extreme Weather Intelligence

DOC-original positions first — official sites only reinforce. NWS / NHC / USGS / SWPC remain life-safety authorities.

DOC independent / proxy parameters — not a radiosonde, not NWS guidance, not RAP/HRRR model-grid data. Do not use for operational severe decisions without official SPC/NWS products.

Disaster categories — DOC first

DOC position

Fire weather

DOC position: treat FIRMS hotspots as decision-support only. Combine Threat Shield / SCRI environment with official fire-weather watches. If hotspots appear within ~40 km of your point, elevate SA and verify wind/RH trends — do not evacuate on hotspot count alone.

DOC position

Space weather

DOC position: space-weather layers on the globe are awareness tools (DONKI flares/CME/GST when NASA key is live). Life-safety for aviation/power is SWPC’s domain. Use God’s Eye + space layer for context, then confirm Kp/alerts on SWPC.

DOC position

Hurricanes / tropical

DOC position: when tropical watches/warnings hit your NWS point alerts, elevate Threat Shield and follow NHC track/cone. DOC does not replace NHC intensity or landfall forecasts — we fuse local alerts + environment proxies.

DOC position

Earthquakes / tsunamis

DOC position: earthquake markers on DOC Globe are USGS-sourced SA. Tsunami life-safety belongs to official warning centers. Use globe fly-to for context; never treat DOC as a seismic network.

DOC position

Floods / hydro

DOC position: for named international floods (e.g. Nepal/China), chat resolves the place and flies the globe — NWS grids do not apply abroad. Inside the US, prefer NWS/AHPS river products; DOC chat + alerts are SA only.
