NWS SKARWARN Oprah KD4KVZ, et al. are relaying Warnings
& other info.

ZELLO's Audio Quality is EXCELLENT, even w/ Over 1,200 logins.

Florida-Local volunteers (eg, ex-Police, Paramedic, oil. Fire Fighter
"TampaGirl76", et al.) are BOTH getting Warnings out, Calming &
Sharing tips w/ folks in the path...

Their ZELLO channel is being broadcast on FaceBook & YouTube.

HAMS NEED TO CONSIDER USE OF ZELLO - over EchoLink -
as Applicable.

Create a New ZELLO Channel & decide between Solo (hear 1 ch.)
and Available (hear live messages [from multiple ch's])..

PS Got Twitter? If so, look for @TheEconomist's video (length 1:23)
~ While the No. of Events has Quadrupled,
   the No. of Deaths from these events is FALLING, in each recent year.

   There is now an app called "WiFi-Talkie" which appears to allow direct communications between individual smart phones without a wifi or cellular connection.

From the WiFi Talkie's app page...

"RANGE OF WI-FI SIGNAL:
The range of Wi-Fi signal depends on a hotspot and connected devices. Usually the range is not more than 50 meters (150 feet) indoors and up to 150 meters (450 feet) outdoors."

Note, it requires a hotspot to operate. It doesn't communicate between phones.

Without the commercial phone network, you can still communicate via wireless mesh networking.  Take a look at two apps that are well developed and stable:The Serval Project and Firechat.

Hams have developed some good mesh networking technology too, as the AREDN have shown.  Cell towers?  Hams ought to be able to work through that...

A mesh network is easy to set up if the area is small such as a FD site or a disaster muster area.  If you hope to cover a whole county getting sufficient equipment in the proper areas is going to be problematic unless your ham population in said county already has an extensive mesh network that could be moved quickly into areas needed or perhaps to an adjacent county.
