Here, for instance, the local NWS transmitter does not include all alerts for the NWS office's coverage area (24 counties across two states) nor our coverage area (which nearly mimics the NWS office coverage) but only the strong portion of its coverage area (a few counties) -- they expect users in its fringe to be listening to the next transmitter over (yes, there is a decent overlap in both RF and provided-alert coverage).

It clearly doesn't include all of those alerts.  As to why... I don't 
know.  I had sent a query to our local office, but they didn't have a 
clear explanation and I didn't pursue it.  What you say may possibly be 
a factor, but we're in mountain country and their main transmitter is 
@1500 feet above average terrain with some pretty wide coverage.  Due to 
terrain, they have a variety of other high altitude transmitters in our 
region, most fed from the same office.

Plus, they voluntarily provide some overlap coverage with neighboring 
transmitters to better support EAS in our region.  The local office was 
one of the first in the country to carry non-weather EAS alerts and it 
isn't uncommon for broadcasters to have their studio (and EAS receivers) 
located where one NWR transmitter can be received, with audience in 
counties that are not.  And our LPs are well away from the "border" of 
the local NWR transmitter's coverage area, but must serve the needs of 
the broadcast stations and cable companies located farther out.  So, in 
general, I'd say it is more likely that our local NWR transmitter(s) 
over cover rather than under cover.
