WPC Hazard Wallboard

About

Road Hazard Wallboard turns official NOAA forecasts into a clear, at-a-glance
board of the weather hazards that actually matter to high-profile vehicles —
semi-trucks, tractor-trailers, buses, and RVs.
It reads the National Weather Service's Weather Prediction Center discussions and
the live NWS active-alerts feed, then organizes what it finds into 16 U.S.
regions so a dispatcher or driver can scan the whole country in seconds.

WHAT IT SHOWS
• Severe thunderstorms, tornadoes, and large hail
• Flash flooding and heavy rain that can cover roadways
• Heavy snow, ice, and freezing rain
• Blowing snow, blowing dust, and dense fog
• Damaging winds strong enough to push or overturn trailers
• Dangerous heat, sourced from live NWS heat warnings and advisories

BUILT FOR DRIVERS
• Full-tab wallboard with color-coded severity for every region
• Compact toolbar popup for a quick glance
• One-click bulletin export in rich text, plain text, or Markdown — paste
straight into email, dispatch software, or a message
• Driver-specific guidance for each hazard (traction, visibility, trailer
stability, tire and engine strain in extreme heat, and more)
• Auto-refreshes on a schedule you choose

ACCURATE AND TRANSPARENT
• Reads official NOAA/NWS text and alerts — no AI guessing, no invented forecasts
• Every hazard on the board links back to the exact source sentence it came from
• Detects "stale" forecasts and refuses to show out-of-date data as current
• Translates technical forecast jargon into plain driving-impact language

PRIVATE BY DESIGN
• No account, no sign-in, no tracking, no ads
• Nothing you do is collected or sent anywhere except the requests to NOAA and
the NWS that fetch the forecast itself
• All settings stay on your own device

CUSTOMIZE IT
• Choose which heat alert levels appear (advisory / watch / warning)
• Filter to the next 1–2 days or the full outlook
• Tune region grouping, wind threshold, refresh rate, and more
• Hide quiet regions to see only where hazards are active
