Do you have MORE than one way to get alerts?

What will one do to keep up with watches and warnings when technology
is slow to respond?

The Graphic, at the right, shows a Twitter account showing the lag between one weather product retweeted by a number of Twitter accounts. At the bottom of the picture, one will observe the Weather Bot sending an
advisory at 12:45 p.m.

Following that, the WX5EM Twitter account transmitted the information
to its stream at 12:19 p.m., a delay of four minutes.

Following that, two media accounts and one emergency management
accounts transmitted the same information to their streams at 12:23
p.m.

An eight minute delay occurred depending on which stream one was
following. "Back in the Day", eight minutes was the best one could
expect for a tornado warning. Today, that time has increased
significantly due to better technology, the Skywarn program, and
social media. However, 15 to 20 minutes is reduced to seven to 12 minutes when there are delays in the Twitter stream. One could build a case that there is little progress, using social media alone for warning transmission.

However, emergency managers have, for years, advised in having more
than ONE stream of information. Apart from a siren, one emergency
management program identified over 7 ways to get information,
including conventional television, radio, internet, NOAA All-hazards
radio, email, text message, and amateur radio.

Do you have three ways to get your warning? What are they? When the
power goes out, do you have three ways to get your warning? Have you
tested them recently?
