Before you drive in snow
- Check the chain rules where you are going: chain and traction tire laws by state, and the controls in force now on chain control.
- The mountain passes, live: Donner, Snoqualmie, Eisenhower Tunnel and the rest. Roads closed for the whole winter are on seasonal road closures.
- All weather warnings: National Weather Service alerts.
Questions
- Where can I see which roads are closed by snow right now?
- On this page, state by state, from the DOTs' own feeds, refreshed every minute; and on each state's page. For chain controls on the mountain passes, see the passes and chain control pages.
- What is the difference between a Winter Storm Warning and a Winter Weather Advisory?
- Both come from the National Weather Service. A warning means heavy snow, sleet or ice that makes travel dangerous is expected or happening; an advisory means winter weather that makes travel difficult, but less severe.
- Why is a road I know is snowy not listed?
- A road is listed when its state's feed reports snow, ice or a chain requirement on it. Many states report only closures and chain laws, not every snowy road, and local roads are not in the feeds.
