You might try inws the weather service has it out now here is the link http://inws.wrh.noaa.gov/
I have found the iNWS alerts to be slow sometimes to the point of not being of any use and if someone relied upon them for safety, they could be in trouble.
(Note: It has been a dismal severe weather season across Indiana so my review will be of the system from early spring. I know they are working to improve the service but if you try it, be aware of possible limitations.)
I compared the iNWS alerts to those send out over the NOAA radio and to StormNow. I have used StormNow for several years and it is an extremely reliable service with alerts sent to my cell phone as quick as the weather radio triggered. It is excellent!
In general I found alerts from iNWS to be delayed usually five minutes or more. Alerts from StormNow arrived on the same cell phone to the same email address virtually the same time as the NOAA weather went off. The iNWS alerts are really nothing more than a very basic header and then a link to the alert (watch/warning). That can take even more time to get the information. (StormNow can send the entire text (or use an abbreviated version - your choice).)
The one cool thing was you could draw your warning area polygon in iNWS so you could really tailor your alert area. StormNow is by entire counties only but you can very quickly make changes and have multiple profiles you can quickly enable/disable.
My conclusion is StormNow for $2.00 a month is way better than iNWS.
When I had a BlackBerry, I used WeatherTap as well for radar and other info and it worked out great. I plan to keep WeatherTap now that I have my Android phone. A great service.
