I have Comcast xfinity. Live in VA. Didn't have TV on at that time..

Been trying some keyword searches & not able to find info.

I can tell u that the federal DHS system that takes over broadcast systems has in past caused people cable etc., to Bo locked up afterwards.. This has been a well publicized problem.. Locked screens, unable to get service afterwards..

Those stories I can find & help pages.

Any alert is of importance, & yes what states they chose to bundle together.. As U check to see if includes those in DHS (fema) 10 federal zones..

Wtf r people on here saying tsunami warning.. First off many of those she listed are inland states.. She is west coast, these r east coast & central..

But worth perhaps U doing a Comcast query...
