useStormEvents:
- Extract windSpeed (windtag), expireTime, warningDurationMins, phenomenaCode/Label
- Calculate polygonAreaSqMi via shoelace formula; estimate homes at 1800/sq mi
StormDetailDrawer — new sections:
- Weather Metrics: hail size with damage descriptor, wind speed with severity label
- Impact Zone: warning area sq miles + estimated homes in zone
- Warning Timeline: issued time, expired time, duration, issuing NWS office
- NWS Boundary note: explains the shape is a meteorologist-drawn warning zone
Map tooltip:
- Shows phenomenaLabel, wind speed, area sq mi
- Footer section labeled "NWS Warning Boundary" with shape explanation
- Fix ReferenceError: hailIn was used before declaration in featureToEvent,
causing every SV event to throw and fall back to empty mock data
- Restore IEM fetch window to 36 months so events are available for all range chips
- Radius input now has explicit Go button (Enter key also applies); draft value
shows hint until applied so accidental keystrokes don't retrigger search
- Map always renders (removed blank overlay when no nearby events)
- Pin radius is now user-configurable (default 5 mi, input shown in pin strip)
- Default date range changed to 6 months for faster initial load
- IEM fetch window narrowed to 6 months to match default
- MOCK_STORM_EVENTS cleared (IEM provides real NWS polygon data)
Search: text filter across areaName/type/severity in sidebar
Pin drop (up to 5 pins):
- Crosshair button activates drop mode; next map click places a pin
- 5-mile radius circle drawn on map for each pin
- Sidebar shows only events within 5mi of any pin, sorted by distance
- Distance label (e.g. "1.2 mi") shown on each card
- Individual pin removal + clear all; + Add pin shortcut in pin strip
- Map shows blank + drop-prompt until at least one pin is placed
More event types:
- Hook now fetches WS/BZ/WW/IS (winter storm, blizzard, ice) from IEM
- SV without hailtag maps to wind; SV with hailtag maps to hail
- New icons: CloudHail, CloudSnow, CloudRain per type
- Type filter row added to filter bar: All/Hail/Tornado/Flood/Wind/Snow/Rain
IEM geojson/sbw.geojson has CORS open to all origins so the browser can
fetch it directly. Moves all transformation logic into useStormEvents.js,
eliminating the need for vercel dev or any server-side proxy. Works with
plain pnpm run dev on localhost. Falls back to MOCK_STORM_EVENTS if IEM
is unreachable. api/storm-polygons.js kept as optional edge cache layer.
api/storm-polygons.js — Vercel proxy that fetches historical NWS storm-based
warnings (severe thunderstorm + tornado) from IEM for WFO FWD (Fort Worth),
covering Collin County / Plano TX. Filters to local bounding box, derives
severity from polygon area (area2163 km²), estimates impacted homes from
density, derives area name from centroid. Cached 12h on Vercel edge.
useStormEvents.js — switched to real IEM data (USE_MOCK=false). Fetches full
36-month dataset once on mount; all range/type/severity filtering stays
client-side in useMemo for instant UI response. Falls back to
MOCK_STORM_EVENTS when /api routes are unavailable (local vite dev).
- Alert/warn forecast cards: day label, temp, and rain% now use high-contrast red/orange text instead of muted gray — readable in both light and dark mode
- Alert card background slightly more opaque (bg-red-100/dark:bg-red-500/15) for better definition
- Range chips: 12 Mo / 18 Mo / 24 Mo / 36 Mo replacing old 1m/3m/6m/1y options
- Custom range: CalendarRange chip reveals two date inputs (from/to) with amber focus ring
- useStormEvents: DATE_RANGE_DAYS updated for new keys; custom range filters by customStart/customEnd; allEvents now uses 36m baseline
Adds a new Storm Intel section to the sidebar and routes for ADMIN and OWNER roles.
- StormIntelPage: full-height layout with Leaflet map + storm polygon overlays,
severity-coded color system, horizontal filter bar (date range / severity / sort),
and a scrollable storm event list
- Storm detail drawer slides in from right with hail size, est. homes, days ago,
conversion window indicator (Hot Zone / Warm / Cold / Too Fresh), intel text,
and quick-action buttons (Create Lead, Open in Dispatch, Assign Canvassers stub)
- Clicking a storm card or map polygon zooms the map to that polygon and opens the drawer
- useStormEvents hook with USE_MOCK flag, date-range cutoff filter, type/severity filter,
sort by date or severity, and conversionWindow() helper
- api/storm-events.js: NWS api.weather.gov proxy (free, no auth needed), parses
GeoJSON polygons and hail size from alert descriptions
- MOCK_STORM_EVENTS: 7 realistic Plano TX storm events with accurate polygon coords
- Sidebar: CloudLightning "Storm Intel" entry added for OWNER and ADMIN nav
