It can you to severe weather conditions in up to five locations and includes a "follow me" mode that tracks you wherever you are.The app works like an emergency weather radio on your iPhone. You will receive critical alerts via voice and push notification regarding major weather events. To learn how to setup your new app: check out our Storm Shield Tutorial. ((See the tutorial.) "Storm Shield to me is the best possible way to warn people about severe weather because not only is it real time, immediate severe weather warnings directly from the National Weather Service, but you can get radar and if you are on the move, if you're traveling, it will find you," said 7NEWS chief meteorologist Mike Nelson. "So, it's the smartest severe weather warning system that has ever been invented."The app can be personalized, so you can decide the type of alerts you want to receive such as tornado warnings, flood watches, fire warnings and winter weather advisories."If the power goes out, you don't know what's going on. But with Storm Shield, you're still going to get your warnings on your smart phone," said Nelson. "And that to me is something that gives people a lot of confidence and peace of mind that they know what's going on when there is severe weather."The app is currently available for iPhone and will be available for Android phones by Sept. 1. The app is $4.99. That's a fraction of the cost of a weather radio and the app does much more.So why should you buy the app?More Precise Alerts - Storm Shield provides more accurate alerts than those offered by typical consumer alerting services. Most services alert you to severe weather if you are in a county covered by a watch or warning, even if you are not actually directly within the watch/warning. Storm Shield ensures you receive an alert only if your device or saved locations fall inside a watch/warning box."Colorado has big counties. You issue a tornado warning for Weld County, you are covering an awful lot of territory when maybe one percent of Weld County that's truly under that warning. With Storm Shield, it will only warn you if you are in danger," said Nelson.Follow Me - The app will alert you if you are in an area when a relevant watch or warning is issued, no matter where you are in the United States."So, if you are driving across country and you happen to be going in Kansas and the sky is looking bad, this will alert you if there is a tornado warning, a flash flood warning in your area," Nelson said.Friends and Family - You can save up to five locations in addition to your current position. This will help you make sure your friends and family in other locations are safe as well.Audio - Storm Shield provides audio alerts in the form of beeps followed by a brief description of the alert type. The audio could wake you in the middle of the night, or give you information you need when you can't stop to look at the phone. Furthermore, you can listen to the alerts and forecasts for your area at any time."I've wanted to see this happen for years, but the technology wasn't there and now we have it with smart phone technology," Nelson said. "The fact that the phone knows where you are with GPS, we can zoom those warnings right down to where you are located."To download the app, search Storm Shield in the App store.
