Also - my wife has been told by her boss that she needs to show up at work tomorrow morning and I fear that the driving condition will be appalling and dangerous, at which point 60 or 80 mph winds will make a difference and possibly a scary one.

This has always been a pet peeve of mine. IF you think your wife's life would be at any type of risk, then by all means she should stay safe. If her boss has a problem with that, tell him to call the local EOC or the Governor's office. No one should ever take any unneccessary risks.
