Best website for winter travel conditions?
 

Where can I find out how slippery the roads are? 511, state police website, and National Weather Service have nothing. 511 only shows things like construction. NWS link goes to 511.

Woops! My error
 

Sorry, I realized there's a way to show slippery conditions at the 511 website.

The 511 site is at http://newengland511.org/ You can uncheck everything except "driving conditions" to see the map more clearly. I notice now that it hasn't been update for the last 7 hours, so if anyone knows of a more current website I'd appreciate it.
