"To: Joe C., Re: Tsunami Warning System"

Hey Joe,
While we don't have an actual warning system in the Atlantic nor the Gulf, CWarn does monitor earthquake events and tsunamis worldwide and send out warnings globally.  You sign up, plug in your lat & long, and phone, they calculate your risk and send you a text message detailing pertinent info. should it be necessary.  Imperfect, you wouldn't have rec'd one about your Christmas adventure, but if the Canaries or the NMF should go, you probably would.
Best of all, it's free.  I think everyone near a coastline should sign up, and if you can, give
a small donation for their work:
