Situation Room · Live data experiment
What's happening around you, right now?
The Situation Room is a live-data operations console: one page that asks several public data systems the same question — what's going on near this point? — and arranges their answers on a map and a set of cards. Weather and official alerts come from the National Weather Service, earthquakes and water data from the USGS, natural events from NASA, tides and space weather from NOAA, and radar imagery from RainViewer.
Pick a location to begin. Every card loads and fails on its own, every answer is labeled with the agency that issued it, and Plain Logic is never presented as the source of an alert — it just arranges the desk. Nothing is tracked, and no location is stored unless you ask for it.
How location works here. Use your location to show nearby weather, alerts, earthquakes, water conditions, and hazards. Your precise location is used for this request and is not permanently saved by PlainLogic unless you explicitly choose to save a location — tick "Save this location on this device" above if you want this browser to remember it.
Situation Room combines public data for informational purposes. About this data · For emergencies and official safety instructions, follow the issuing agency and local authorities.
No location chosen yet. Live cards that need one are waiting; space weather, natural events, and radar load without one.
How this page gets its data
Live request state: a source lights up only when this page actually asks it. Served-from-cache answers reuse the last good data without a new request, so they carry no particle.

Preparing the map
The WebGL map loads only when you scroll it into view, so it never slows down the rest of the page. If it can't load, the cards below carry the same data.
The map couldn't be started. The card set below carries the same live data — nothing else is affected.

Plain Logic is not the issuing authority for any alert shown here. For official warnings and instructions, follow the source agency. Alert zones drawn on the map are approximate areas built from the National Weather Service bounding box, not official zone boundaries. Radar imagery: Weather data by RainViewer.
What this page actually is
The Situation Room is the flagship experiment of the Plain Logic lab: a simplified GIS console that watches several public data systems at once and answers one question — what's happening around me right now? — without sending you to five different agency websites. Pick a point, and the page pulls the current weather, official alerts, earthquake activity, nearby water gauges, coastal tides, space weather, and precipitation radar for it.
The map is the centerpiece. Toggleable layers draw NWS alert zones, animated RainViewer radar, USGS earthquake markers sized by magnitude, NASA natural-event markers by category, USGS water gauges, and the nearest NOAA tide station. Below it, nine cards carry the same feeds in plain language, with short deterministic summaries like "best dry window appears to be 3–6 PM" — rules over the data, not an AI making things up. There is no language model on this page. If a feed didn't report it, the page doesn't say it.
Where the data comes from
Every number on this page arrives from a public source, through a small proxy that normalizes the formats. The sources are always named where their data appears, and Plain Logic claims none of it as its own.
- Weather & alerts
- National Weather Service (weather.gov) for current conditions, forecasts, and official alert text.
- Earthquakes
- U.S. Geological Survey (earthquake.usgs.gov) earthquake feeds; markers drawn from the public GeoJSON feed.
- Water data
- USGS Water Services for stream and groundwater monitoring stations and their current readings.
- Natural events
- NASA EONET (eonet.gsfc.nasa.gov), the Earth Observatory natural event tracker.
- Tides & space
- NOAA CO-OPS tide predictions and the NOAA Space Weather Prediction Center (swpc.noaa.gov).
- Radar
- RainViewer (rainviewer.com) composite radar tiles, animated through past frames.
- Map tiles
- OpenFreeMap (openfreemap.org), rendered from OpenMapTiles and OpenStreetMap data.
How to read this page, honestly
This is not an official warning system. Plain Logic is not the issuing authority for any alert shown here; it is a display that quotes the agencies that are. If an alert matters to you, read the full text from the National Weather Service and follow its instructions, not this page's summary.
Read the full disclaimer — it covers what these summaries are, what they are not, and who to follow in an emergency.
Alert zones on the map are approximate affected areas drawn from bounding boxes, labeled as such — never official zone boundaries. Timestamps under each card tell you when its feed last answered ("updated 4 min ago"), and each source loads and fails independently, so a red dot on one card is a problem with that feed, not with the page. Geolocation is opt-in, and your coordinates stay in this tab unless you tick "save on this device."
