According to the news reports, the worst flooding is in Keene (near her town), but her actual town is uphill of it. Sometimes evacs are called on account of lack of emergency services when closed roads cut them off-- not necessarily because an area is going underwater.
Also, in hilly country the danger is not pooled water rising, but runoff-- boulders and trees washing down narrow streams and taking houses and infrastructure out with them. In our area, people get this a lot; those who are in a vulnerable area know it and know how to watch the signs. So again I would bet she's just fine and busy helping other folks or long gone to a safer place.
