Rachel and I find that we weren't always as cautious about upcoming storms prior to being parents.  However, after the tornados a couple years ago that hit Murfreesboro pretty hard, we pay more attention now.  Since we're on the road quite a bit, I had been researching what the best mobile alert system was for a smartphone. 

After researching them all, I found the iMap Weather Radio was the right choice for us.  It is one of the few that sends Push Notifications to your phone, so it will alert it whether on standby or being used at the time.  Plus, many just ding...I wanted to be alerted.  Simply a ding, like receiving an email, wouldn't wake us up.  After the initial alarm, a voice comes on and explains the warning.

The app is just $9.99 and more information can be found her:  http://www.wdtinc.com/pages/imapweather_radio

Stay safe tonight!
