As for the communications network - what is being done right now to deal with polygon warnings that cover multiple counties?
So far - nothing. Most SR offices still don't use polygons as they just draw the boxes to match county outlines. It's unfortunate since I do think it's a good idea to implement, but until all of the NWS starts using them next year there's not much for the vendors to do. And as long as no cross-CWA warnings are issued, vendors won't need to do anything different.
