I went through some of this recently.
I'm on a travel contract in Oregon and the entire town I am housed in was evacuated.
I was at work on night shift when the house supervisor came around and asked me where I was living. When I replied she told me that there was an alert for possible evacuation in that area. Fifteen minutes later she came back and told me it had been upgraded to "Leave now.".
I have a friend traveling with me so I had to clock out, drive home, wake her and grab a few things and get out.
Luckily the hospital is in a different town so I was able to get a motel room and avoid staying at a shelter so I could continue working.
Just to top things off, Hurricane Irma was at the same time so my mother and my house were in the path of that. Thanks to cell phones we were able to keep in touch during our mutual evacuations.
