Here’s one for the weird and strange category. Somebody playing a joke I guess.

More strangeness, one article said notification was received by email and another article says the notification appeared on Twitter.

The fake message was circulated at 4 p.m. or so on a global telecommunications system used by the World Meteorological Organization :?

Now the FBI has gotten involved.

What I glean from all this and what I find rather concerning, is if it had not been Fabricated.
i.e. who actually received it and who should have.
