For those who may be interested, there is an app for smart phones called "Code Red".
Provides alert information, customized to the individual wants as well as how to be notified.
A similar program is avaialable through the Sumter County Sheriff's web site (I do not know the availability at other sheriff's offices or not).
Go to
Welcome to the Sumter County Sheriff's Office Website
go to left side and scroll down to Code Red and proceded.
I have registered with both.
My weather radio did not function at all last night. Working with nothing but static.....must be time to replace.
