A couple hotels in Napa evacuated guests and will be closed for at least a few days. Some roads are buckled but still open, so traffic could be slower than usual. Parts have no electricity. At a press conference earlier today, they said that there were at least sixty water main ruptures, which are expected to take a week to fix. Other problems reported today included gas leaks.

It wasn't clear from news reports whether Sonoma was also affected, although people often travel to Sonoma through Napa, which could be a problem.
