I left out the 14325 kHz Natl. Hurricane Watch Net, because I did not know whether or not it was still active for Harvey. There's another tropical disturbance off the US East Coast, and if it develops the HWN may activate again.
Frequencies that have already been confirmed active in Harvey are in boldface.

In addition, there is activity on the COTHEN net, though I haven't heard any voice comms here yet. This net was a mainstay in Katrina, and while I realize that's 12 years ago, and that its primary mission remains law enforcement, maybe it will be used again. It's primarily USB ALE, though follow-on voice comm is frequent.
