To protect yourself in the interim, get a new weather radio that supports SAME. The SAME system, combined with the new (as of October 1st) localized "threat based polygon" warnings being used by the National Weather Service will give you alerts for your specific area and not the entire metropolitan area where you reside.

 

This new system will give you better information than TWC 8's since you won't have to be married to TWC continuously to get your alerts.

 

I've not had the Local on the 8's for years and I'm never lacking for my local weather information.  With the flaky nature of power and TV service in severe weather, relying solely on the TV for your weather alerts is careless.
