LESS MAP HUNTING. MORE UNDERSTANDING.
Not just what’s happening.
What matters to your drive.
A destination forecast misses the journey. Put the important checkpoints on one timeline, then see what changes if you leave later.

A few things worth knowing.
A useful answer should make its limits just as clear as its result.
See every data boundaryDoes this tell me whether a road is open?
No. Weather forecasts and current road restrictions are separate layers. The report identifies its available source data and links to the relevant authorities; missing information is never an all-clear.
Can I enter any starting point and destination?
The checker currently supports ${ROUTES.length} curated corridors in either direction, not arbitrary address-to-address routing. The route directory shows the exact endpoints and selected checkpoints.
Do I need an account, and is my trip saved?
No account is needed. Route presets, reports and trip plans are saved in this browser only when you choose their Save action. These use separate storage keys. A saved report is not automatically refreshed.
Are later departures always better?
No. The same checkpoints are checked for four departure samples. A fair comparison requires the relevant data to be available. A lower weather-concern category is not a safety clearance or an expected reopening time.
MAKE THE NEXT DRIVE A LITTLE CLEARER
Check the road ahead.
Weather context first. Official road instructions always.
