Where our conditions come from

🔴 How fire alerts are localized & triple-checked

Fire danger is the one place a wrong call is dangerous, so this is the most conservative part of the site — quick to raise, slow and confirmed to clear, and it always fails toward caution.

• Geography. A Red Flag Warning is shown only if it provably covers the lake — its NWS fire-weather zone includes 37.40, −107.55, or a point-in-polygon test of the alert's mapped area contains the lake. An adjacent area's warning is logged but not shown.
• Corroboration. To raise, one confirmed NWS read is enough. To clear, the point-coordinate feed and the zone feed must both agree there's no warning.
• Time (debounce). A warning clears only after its official end time has passed and two spaced reads (~30 min apart) confirm it's gone. A skipped or failed check resets that count. A thrown error, an empty response, or a stale read holds the last state — it never clears it.
• The human gate. Red Flag Warnings clear automatically on their official, dated end time. Restriction reductions (lifting a Stage 1/2 ban) do not — those wait for a person, because bans are lifted by orders we can't reliably parse. After 7 days pending we relabel “reported lifted — verify,” but still never silent-clear.
• Transparency. Every state shows its source, a timestamp, and a direct link to the official NWS alert or Forest order, so you can always check the primary source yourself.

This makes the awareness trustworthy — it doesn't replace the official channels. Always verify evacuation and closure orders with NWS, the Sheriff, and the Forest Service.
