What you are referring to are predicted environmental conditionsat the
macro level. I'm referring to those events not readily predictable with
any level of precision at the micro or nano level. There is no
contradiction. The widely disseminated predicted environmental
conditions are really a macro level situational awareness message.The
NWS may issues watches for those events...but thewatch criteria varies
by event.
The EAS and associated alerting relay networks are for events in
progress or projected to occur with some specified imminence and higher
confidence over a confined area and timeline requiring call to action
within that environment. Again, no contradiction except where media is
reporting the events in progress.
Like outside sirens are meant for only those outside of buildings, EAS
is only for those who are engaged in media or have a means to be
notified by same through an automated notification system either by Part
11 partners or others within IPAWS.But EAS won't reach everyone...and
I'm not so sure we should seek that.
The term "flash" flood has been so widely abused that much of the
original meaning has been lost. Most flash floods are of flatland
waterways which run out of their banks by some marginal amount within 6
hours of a rain event. The true meaning of "flash flood" is better
applied to valleys and those waterways where literal walls of water
cascadedown from higher ground within minutes of the rain event offering
no or little advance warning. Not hours where there is some amount of
time and situational awareness to at least execute some measures or plan
for water inundation.
Would mudslides fit into that box, sure. But again, on a micro or nano
level basis. Much the same as avalanches. They're confined to a very
prescriptive area.
