Weather intelligence for every mile
AI-written route briefings, live weather alert polygons, a truck-driver hazard engine, and a Time-Table departure picker — all tied to the exact minute you expect to be there.
Built for drivers, not for dispatchers
Every feature ties back to one question: what’s the weather going to do on my route, and when?
AI Route Briefing
A 3–5 sentence, plain-English summary of weather along your exact route, generated on demand by Cloudflare Workers AI.
- Llama 3.3 70B FP8 summarizes weather + alerts + derived hazards
- Highlights notable weather changes mid-trip
- Mentions the worst window and calls out what to watch for
- Never invents conditions — grounded on the live forecast we send it
- One tap from the briefing card
Route-Aware Forecasts
Authoritative gridded weather data sampled along your route and time-aligned to the minute you expect to be there.
- 25+ variables per sample: temp, dewpoint, wind, gust, visibility, ceiling, precip, snow, ice
- 8 sample points across the route with the full variable grid
- Each sample resolved at its predicted arrival time, not "now"
- In-memory caching keeps replans instant
Live Alert Overlay
Winter Storm Warnings, High Wind Warnings, Dense Fog Advisories, and the rest — rendered as severity-colored polygons on the map.
- Zone and county geometries resolved from /alerts/active automatically
- Point-in-polygon filtered against the actual route path
- Tap any polygon for the full event, headline, instructions, and expiry
- Inline accordion on the briefing card — no modal required
Truck-Driver Hazard Scoring
Six rig profiles scored against FMCSA-aligned operational thresholds — not generic weather warnings.
- Blow-over thresholds from FMCSA + ATA + WY-DOT I-80 corridor criteria, by rig profile (RV, box, 53' loaded/empty, doubles, triples)
- Crosswind: wind component perpendicular to your heading at the exact ETA per segment
- Black-ice risk: temperature ≤ 33 °F + measurable precip
- Whiteout / blowing snow: snow + wind ≥ 25 mph + visibility
- Hydroplaning, fog, severe weather (SPC outlooks), and active NWS alerts intersected with your route
- Every threshold cited inline in source — auditable, not magic numbers
Time-Table Departure Picker
Sweep the next 12 hours hour-by-hour and pick the calmest window. Rescoring takes a second — forecast data is already cached.
- Each candidate scored with the same hazard engine as the live briefing
- Active alerts intersected against the trip window (effective → expires)
- Recommended window called out at the top
- Tap any row to replan with that departure
Animated Precipitation Radar
Live radar overlay with crossfade playback — so you can see what’s coming and where it’s heading without leaving the map.
- Refreshes automatically as new frames publish
- Past frames with smooth cross-fade playback
- Frame-by-frame scrub control in the corner
- Color-coded reflectivity, tuned opacity
Saved Routes
Pin the runs you drive regularly. One tap to replan with today’s weather.
- Unlimited saved routes on the Premium plan
- 365-day route history for retrospectives

Mobile-First PWA
Installable as a web app on iOS and Android. Safe-area aware, touch-friendly, and no pull-to-refresh footguns.
- Glassmorph UI tuned for in-cab readability
- Respects device safe-area insets (notches, gesture bars)
- Auto-reloads when we ship a new version
- Works offline for the app shell
