[EAS] NWS Fun

[Mike McCarthy]

I dunno...

FFW is a very localized, short fused, and highly perishable message. FFW's
are typically followed up by an areal flood warning or a simple flood
warning if there is a larger flood episode. I rarely see a FFW renewed
unless the area has a fresh FFW for a different storm.

The intent of the FFW is get people's attention to the fact a fast
occurring flood is developing or in progress where it may not be evident.
Especially in river basins, dry gulches, and floodways where a wall of
water with no warning can appear from a heavy rain event many miles
upstream.

It carries the same hazard threshold as a tornado or tsunami.
