- nws.js: new fetchActiveAdvisories() hits the official NWS alerts feed
(api.weather.gov /alerts/active?point=lat,lon) and normalizes each advisory
into the app's alert shape, tagged source:'nws'. Adds classifyAdvisoryEvent
(maps NWS events -> app buckets: heat/wind/cold/storm/precip, else advisory),
nwsSeverity (Extreme/Severe->danger etc.), advisoryId (stable short id from
the URN), advisoryIcon, and local effectiveDate/expiresDate for dedup.
- notifications store: cached _nwsAdvisories + refreshAdvisories() (best
effort, cached 5 min, non-US/no-alerts safe). analyze() now merges
advisories via new pure mergeAdvisories(): an advisory that is officially
in force on a date supersedes the derived forecast alert of the same type
on that date, so the official NWS warning replaces the forecast guess. Both
are dismissible independently (nws-* vs forecast-* ids).
- New per-type toggle "advisory" (defaults on) across app/default settings and
SettingsDialog, so official advisories are configurable like every other
alert and the bell shows them with their own severity/icon.
- Wired: App.svelte calls refreshAdvisories() alongside analyze() on forecast
load and changes.
- Tests: 12 advisory tests (classifier, severity, id, normalize, dedup incl.
disable toggle) + 3 store integration tests (overlap dedup, non-overlap kept,
toggle-off). 107 total pass.
- Verified end-to-end in headless Chromium against the live NWS feed for
Rogers County, OK: the current Heat Advisory appears in the bell, and the
derived heat alerts for the days it covers are suppressed while a
non-overlapping day's forecast heat alert remains.
- New src/lib/api/moon.js: fetches daily moon_phase from Open-Meteo
(independent of the NWS/Open-Meteo weather source, since NWS has no moon
data), plus pure helpers: moonName (8 phases), illumination fraction, and
nextMoonPhase, which unwraps the ~29.5-day cycle and interpolates the next
quarter boundary (new/first quarter/full/last quarter), returning its name,
date, and days until it.
- New MoonPhaseCard.svelte: renders an SVG moon (two-circle terminator that
correctly shows crescent/quarter/gibbous shapes), the current phase name,
percent illuminated, and the next phase with date. Caches per-location via
an effect; degrades gracefully when unavailable.
- Wired into WeatherDetail between Sun and UV and Temperature Range.
- 11 unit tests for moonName/illumination/interpolation/nextMoonPhase.
- Verified in headless Chromium: card renders, moon shape correct, no errors.
- manifest.webmanifest + apple/maskable PNG icons; relative paths so the
app works both at dev root and under /weather
- plain-JS service worker (sw.js) with notificationclick/push handlers and
an SW-mediated showNotification() path for native Android notifications
- src/lib/pwa.js bootstraps registration and routes alerts to the SW
- Every alert kind (storm/precip/heat/cold/uv/wind) is now a per-type
preference toggle in Settings; removed the old alertThresholds.thunderstorm
boolean in favor of notificationTypes.storm
- Store dedups native notifications per forecast day and fires best-effort
native notifications for newly-appeared alerts
- inline-assets keeps manifest/sw/icons in dist; deploy.yml uploads + verifies
all PWA files via WebDAV
- New src/lib/router.js: parseHash/ viewToHash for the 5 tab views, with a
default fallback for empty/unknown hashes.
- App.svelte: initialize viewMode from location.hash, setView() updates both
state and the URL hash, and a guarded hashchange listener syncs back/forward
and manual URL edits. All tab onclicks route through setView().
- Tests for parse/viewToHash round-trips and fallback. 76 total pass.
- Lightning layer on PrecipitationRadar: toggleable ⚡ button (persisted via
showLightning setting). When on, fetches recent strikes from the planned CORS
relay and renders them as markers that pan/zoom with the slippy map.
- New src/lib/api/lightning.js: fetchLightningStrikes() reads
https://cors.thecookiejar.me/lightning?lat&lon&radiusKm&limit (relay NOT
deployed yet) with an 8s abort timeout and graceful failure - never blocks or
crashes the map, shows an unavailable banner instead. Exports pure
projectStrikeToLayer() for Mercator tile-layer marker projection.
- showLightning setting added to DEFAULT_SETTINGS + app store; toggle persists.
- Tests: fetch URL/parsing/error handling + layer projection. 71 total pass.
NWS doesn't publish pressure (its pressure series is empty) or a UV index.
When the selected source is NWS, merge current.pressure_msl, current.uv_index
and daily.uv_index_max from Open-Meteo and tag them via data._fallback so the
Current + Details views show a tooltip noting the value came from the
non-selected source (Open-Meteo) instead of showing 0 hPa / --.
NWS text like 'Slight Chance Showers And Thunderstorms' (~17-24%) was mapping
straight to WMO 95 / thunderstorm icon, over-stating a mere chance of storms.
shortForecastToWmo now takes the period's precip probability (plus chance-like
wording) and downgrades low-chance storms to light showers (80) and low-chance
rain to light rain (61), keeping real/severe storms at 95. This also stops the
false thunderstorm alert banner for low-chance days. Today/Monday for Rogers
County now render as showers instead of storms.
- New Settings > Data source toggle (Open-Meteo global / NWS US); NWS
falls back to Open-Meteo when unavailable or outside its coverage.
- src/lib/api/nws.js: /points -> forecast/hourly/grid normalizer producing
the app's shared shape, with realistic air highs (NWS reports 104 for the
day Open-Meteo over-forecasts at 116); heat-index/feels-like falls back to
air temp since NWS returns apparentTemperature as null here.
- NWS requires a User-Agent contact; email is a build-time Vite env
(VITE_NWS_EMAIL), read from gitignored .env.local, never committed.
- Details view now shows which provider served the data.
- Fixes the identical UTC date-parse shift for NWS naive local times.
- Tests (8) + recorded live fixtures for Rogers County, OK.
