OZARK, Mo. -- Christian County, Mo. is turning to your smartphone to notify you of dangerous weather. It's called the Swift 911 app.
"Road closures, flooding, basically any kind of notification that you could think of, we're able to notify anybody that's signed up on the system," said Sheriff Cole.
The most recent widespread notifications happened after the April 30 tornadoes near Ozark. The app let the sheriff's office and emergency management share important information about road closings.
"If we have a large scale major incident where we need everybody notified all at one time, as quickly as possible, we can push that information out to our deputies and give them the information on where we need them to respond to and what we need them to do," said Sheriff Cole.
The app has 30,000 users.
