Storm-Based Warnings Coming This Fall

Beginning in October, the National Weather Service will begin issuing warnings for tornadoes, severe thunderstorms, flash floods, and marine hazards based on storm size, direction, and location as opposed to their current method of county-based warnings. For example, this means instead of issuing a warning for, say, Allen County Indiana, a warning will be issued for a discrete polygon drawn on a map by an NWS meteorologist. I'm assuming by debuting this in October, they will be using this year's severe weather season as a test for this new method.

There are still quite a few unanswered questions in regard to how this will work. How will the the weather radios with SAME technology, which use FIPS codes that function with the Emergency Alert System on a county-by-county basis, adapt to this new method? How will the television warning graphics adapt? I'm sure this is all worked out already, but I haven't found information on it yet. It will be interesting to see how this works when it comes online in October.

I appreciated your weather report. It's stormy here, too, and still raining. I also enjoyed looking at your photos. Aunt Janet
