This is the stated purpose of 4WarnMe .
As a layman, it seems 4WarnMe , with many users, asks for the most information to be passed over cellular nets during periods of peak bad weather. 4WarnMe slows noticeably or ceases to update during those times.
Therefore it would seem smart for the developers should actively seeks ways to maintain weather awareness while using minimum bandwidth. How hard would it be to stream text only of the 4Warn TV team? On the TV broadcast, they provide street to street or in the hinterlands, location to location, progress of tornadoes. Cellular coverage is worse in the rural regions. The affiliated radio partber, KTOK, has to lower signal strength at dark so rural users lose that source of the repeated signal. NWS radio gives quarter county resolution of stirm conditions at best.
Simplify the stream, and provide a text stream for peak demand times that can make it to users. Weather awareness is the point of 4WarnMe .
