The saved route
The recorded route runs through DuPont, Winlock and Ridgefield between Seattle and Portland. Temperatures range from about 0°C to 3°C, with no precipitation in the saved forecast.
Hazards in the example
The analysis flags black-ice risk at all five points. These are forecast-based risk flags; the snapshot does not confirm ice on the road. Wind remains light in the stored weather values.
Along the route
Winlock is the coldest point at −0.35°C. Seattle, DuPont and Ridgefield are close to freezing, while Portland is 2.62°C. The route view makes that small but relevant temperature variation visible.
Departure timing
The saved departure is 1:00 a.m. Pacific time on March 30. This example contains no alternative departure comparison, so it does not establish a safer hour for the ride.
What to plan around
Review the near-freezing forecast points and possible-ice warnings along the ride. Check current road reports before deciding whether to ride or change the plan.
